Complete EGR Valve & Cooler Delete Kit for 2006-2007 GM Duramax LBZ 6.6L Diesel This comprehensive EGR delete kit completely removes the failure-prone EGR valve and EGR cooler assembly from your 2006-2007 Chevrolet Silverado or GMC Sierra equipped with the legendary 6.6L Duramax LBZ diesel engine. The LBZ's EGR system is a known weak point — cooler failures can lead to catastrophic coolant loss, hydrolock, and engine damage. This kit eliminates that risk permanently while improving airflow, reducing intake temperatures, and simplifying the engine bay. ⚠️ OFF-ROAD USE ONLY: This product is intended solely for off-road, racing, and competition vehicles not operated on public highways. Removing or tampering with emissions control equipment is prohibited by federal law for on-highway vehicles. Verify local regulations before purchasing. Key Features Complete System Removal: Includes blocker plate, coolant bypass fittings, intake manifold block-off, and all required hardware — removes both EGR valve and cooler Billet Aluminum Up-Pipe Block-Off: CNC-machined 6061-T6 aluminum block-off replaces EGR feed from passenger side up-pipe — zero exhaust gas reaches the intake Coolant Reroute Kit: Includes brass hose barb and high-temperature silicone cap to properly bypass EGR cooler coolant circuit without restricting heater core flow Prevents Catastrophic Engine Failure: LBZ EGR coolers are known to rupture internally, dumping coolant directly into the intake — this kit eliminates that failure mode entirely Improved Throttle Response: Removing EGR reduces intake air temperature by up to 100°F, increasing air density and improving combustion efficiency Compatibility Year Make Model Engine 2006-2007 Chevrolet Silverado 2500HD/3500HD (Classic) 6.6L Duramax LBZ (RPO: LLY/LBZ) 2006-2007 GMC Sierra 2500HD/3500HD (Classic) 6.6L Duramax LBZ (RPO: LLY/LBZ) Technical Specifications Component Material Detail EGR Blocker Plate 304 Stainless Steel 3mm thick, laser-cut to port Up-Pipe Block-Off 6061-T6 Billet Aluminum CNC-machined with O-ring groove Coolant Bypass Fitting Brass 3/4 inch hose barb Silicone Cap High-Temp Silicone Rated 400°F continuous Intake Block-Off 304 Stainless Steel Precision-fit with gasket Why Delete the LBZ EGR System? The Duramax LBZ is widely considered the best pre-emissions Duramax engine — but the EGR system is its weak link. When the EGR cooler fails internally (common on high-mileage LBZs), coolant is drawn directly into the intake manifold. Best case: white smoke and coolant loss. Worst case: hydrolock bends a connecting rod. This kit permanently removes that failure mode. Your LBZ will run cleaner, cooler, and more reliably for the long haul. Frequently Asked Questions Q: Does this require an ECU tune to prevent check engine light?A: Yes. Removing EGR triggers DTCs P0401-P0406. A custom ECU tune disabling EGR-related DTCs is required to prevent CEL and limp mode. EFILive and HP Tuners support this modification. Q: Will this affect my cooling system?A: No. The kit includes a coolant bypass fitting maintaining proper flow through the heater core circuit. EGR cooler is isolated without restricting flow to other components. Q: How long does installation take?A: Plan 4-6 hours for first-time DIY. Hardest part is accessing EGR cooler bolts on passenger side. Professional shops typically complete in 3-4 hours. Q: Does this fit the LLY (2004.5-2005) Duramax?A: No, this kit is specific to 2006-2007 LBZ. The 2004.5-2005 LLY uses a different EGR cooler design and up-pipe configuration. Verify engine RPO code before ordering. Q: What tools do I need?A: Metric socket set (8mm-15mm), extensions and swivel adapters, torque wrench, flathead screwdriver, hose clamp pliers, coolant catch pan. 📚 Related Guides & Articles Chevy/GMC Exhaust Header Buyer's Guide SBC vs LS Engine: Header Upgrade Guide Dodge Ram Exhaust Header Installation Guide Mopar 5.2L 5.9L V8 Header Upgrade

1478 Electric Choke Conversion Kit for Edelbrock 1405/1406 Carburetors The iFJF 1478 Electric Choke Kit converts your manual-choke Edelbrock 1405 (or replaces a worn electric choke on the 1406) to automatic 12V electric choke operation. No more fishing a choke cable through the firewall — just pump the gas once, turn the key, and the thermostatic choke element handles cold-start enrichment automatically. Key Features Direct Fit — Bolt-on replacement for Edelbrock 1405 and 1406 Performer Series carburetors 12V Electric Operation — Connect to any ignition-switched 12V source for automatic choke function Thermostatic Element — Bimetallic spring opens the choke plate progressively as the engine warms up Includes All Hardware — Choke housing, thermostatic element, fast idle cam, linkage, screws, and gasket Adjustable — Rotate the housing to fine-tune choke opening rate for your climate and engine setup Vacuum Pull-Off Compatible — Works with the existing internal vacuum piston on your 1405/1406 Compatibility Carburetor Model Application 1405 Performer (Manual Choke) Converts manual to electric choke 1406 Performer (Electric Choke) Replacement for worn/failed electric choke Installation Overview Remove the manual choke housing (3 screws) from the passenger side of the carburetor Install the new choke housing with the provided gasket Connect the fast idle linkage to the choke shaft Route the 12V wire to an ignition-switched power source Adjust the choke housing index to set the correct opening rate Frequently Asked Questions Q: Will this fit my 1405 carburetor? A: Yes — the 1478 kit is specifically designed as a direct bolt-on conversion for the Edelbrock 1405 manual choke carburetor. It also fits the 1406 as a replacement electric choke unit. Q: Where should I connect the 12V wire? A: Connect to a key-on 12V source such as the ignition coil positive terminal, the IGN terminal on the fuse box, or a switched 12V circuit. Do not connect to constant 12V — the choke element will drain the battery when the engine is off. Q: How do I adjust the choke? A: The choke housing has index marks. Rotate clockwise (richer) for colder climates or engines that need more warm-up enrichment. Rotate counter-clockwise (leaner) for warm climates. The factory setting (center mark) works well for most applications in temperate regions. Q: Do I need to re-jet after installing the electric choke? A: No. The choke only affects cold-start and warm-up enrichment. Once the engine reaches operating temperature, the choke is fully open and has zero effect on the main fuel circuit. Q: Can I install this without removing the carburetor? A: Yes — the choke housing is accessible on the passenger side of the carburetor and can be swapped with the carburetor installed on the engine. The job typically takes 15-30 minutes. 🔗 Related Products from iFJF 1405 Performer 600 CFM Carburetor 1406 Performer 600 CFM Carburetor 📚 Helpful Installation Guides 📖 How To Rebuild Edelbrock 1406 and 1405 Carburetors | Rebuild Kit Links 📖 iFJF 1403 Performer 500 CFM 4-Barrel Carburetor Installation Guide 📖 Related Guide Installing a Performer-pattern 4-barrel?

This choke automatically enriches the fuel mixture during cold starts using a 12V electric heating element — eliminating the need for manual choke cables or operator intervention. Replaces OEM 70125A-1 and Sierra Marine 18-7665. Key Features Automatic Electric Operation: 12V heating element progressively opens the choke plate as the engine warms up — no cables, no manual adjustment. Direct OEM Replacement: Precision-fit for Mercruiser 2-barrel Mercarb carburetors. Replaces OEM 70125A-1 and Sierra 18-7665. Improved Cold Starts: Provides the correct cold-start fuel enrichment for instant starting and smooth warm-up, even after extended storage. Corrosion-Resistant Construction: Designed for the harsh marine engine compartment environment — resists salt air corrosion and humidity damage. Plug-and-Play Installation: Connects to the existing 12V ignition-switched power source. Uses the same mounting pattern as the original choke. Compatibility Engine Carburetor Application Mercruiser 3.0L (181 ci) 2-Barrel Mercarb Sterndrive, 4-cylinder, various years Mercruiser 3.0LX 2-Barrel Mercarb Sterndrive, 4-cylinder Mercruiser 3.0L MPI (Verify) N/A — Fuel Injected ❌ Not Compatible — MPI models don't use carburetors Cross-Reference Brand Part Number Sierra Marine 18-7665 Mercruiser OEM 70125A-1 Signs of a Failing Electric Choke Hard cold starting: Choke doesn't close fully — engine cranks excessively before firing. Engine stalls when cold: Choke opens too quickly, leaning out the mixture before the engine is warm. Black smoke / rich running when warm: Choke stays partially closed — heating element has failed. Rough idle after cold start: Choke opening inconsistently due to intermittent electrical connection. High idle persists too long: Heating element weak — choke takes excessive time to fully open. Installation Overview Disconnect battery negative terminal (safety first in marine environments). Remove the flame arrestor / air cleaner assembly. Disconnect the old choke electrical connector. Remove the old choke assembly (typically 2-3 screws on the carburetor housing). Install the new iFJF 18-7665 choke, ensuring the choke plate linkage engages correctly. Connect the electrical lead to 12V ignition-switched power. Verify choke operation: cold engine → choke plate should be nearly closed. Apply 12V → plate should slowly open over 2-5 minutes. Frequently Asked Questions Q: Does this fit all Mercruiser 3.0L engines?A: This choke fits Mercruiser 3.0L engines with the 2-barrel Mercarb carburetor. It does NOT fit 3.0L MPI (multi-port fuel injection) models, which don't use a carburetor or choke. Verify your engine has a carburetor before ordering. Q: How do I test my existing choke?A: With a cold engine, remove the flame arrestor. The choke plate should be nearly closed. Start the engine and observe — the plate should slowly open over 2-5 minutes. If it stays closed after 5+ minutes, the heating element is dead. If it snaps open immediately, the bimetal spring is broken. Q: Does this require 12V constant or switched power?A: Connect to ignition-switched 12V (only powered when the key is ON). Connecting to constant 12V will keep the choke heating element energized and drain your battery. Q: Can I adjust the choke opening speed?A: The opening speed is determined by the heating element and bimetal spring — not user-adjustable. However, you can adjust the initial choke plate gap via the choke housing rotation. Mark the original position before removal. Q: Is the gasket included?A: If the kit includes a mounting gasket, it will be in the package. If your original gasket is in good condition, it can be reused.

Product Overview Address two of the most common 6.7L Cummins reliability issues in one comprehensive kit with the iFJF CCV Reroute & EGR Valve Delete Kit. Engineered for 2007.5-2018 Dodge Ram 2500 and 3500 trucks, this combination kit eliminates the problematic EGR (Exhaust Gas Recirculation) valve that introduces hot, soot-laden exhaust into your intake — while simultaneously rerouting crankcase oil vapors away from the turbocharger inlet. The result: a cleaner, cooler-running engine with improved throttle response and long-term reliability. ⚠️ OFF-ROAD / COMPETITION USE ONLY: This product is intended for off-road, racing, and competition vehicles only. Removing emissions equipment is prohibited for on-highway vehicles under the Clean Air Act. Check local, state, and federal regulations. Key Features Dual Protection System: Combines CCV reroute (prevents oil mist in intake) with EGR valve delete (prevents soot/carbon buildup) for complete intake system protection. CNC-Machined Components: Both the CCV housing and EGR delete plate are precision-machined from 6061-T6 billet aluminum with black anodized finish for maximum durability. Eliminates Carbon Packing: Prevents the notorious carbon/sludge mixture that forms when EGR soot combines with CCV oil mist inside the intake manifold. Lower EGTs: Blocking exhaust gas recirculation reduces intake air temperatures and lowers exhaust gas temperatures during towing and heavy load conditions. Complete Installation Kit: Includes CCV housing, EGR valve delete plate, gaskets, O-rings, Grade 8 hardware, and vent hose — everything needed in one box. Comprehensive Coverage: Fits all 2007.5-2018 Ram 2500/3500 with the 6.7L Cummins turbo diesel engine. Compatibility Year Make Model Engine 2007.5-2018 Dodge / Ram Ram 2500 / 3500 / 4500 / 5500 6.7L Cummins Turbo Diesel Specifications Specification Detail CCV Housing Material 6061-T6 Billet Aluminum, Black Anodized EGR Plate Material 6061-T6 Billet Aluminum, CNC-Machined O-Ring Type Viton (high-temperature rated) Hardware Grade 8.8 / Grade 8 bolts Fitment 2007.5-2018 Ram 2500/3500/4500/5500 6.7L Cummins Installation Bolt-on, professional install recommended Why Choose iFJF iFJF Direct's combination CCV + EGR kits provide the most cost-effective path to protecting your 6.7L Cummins intake system. Rather than buying two separate kits and hoping they work together, our engineers designed these components as a unified system. The CCV housing and EGR plate share the same material spec, finish, and quality standards — giving you a consistent, professional-grade installation. Frequently Asked Questions Q: Will this fit my 2013 Ram 3500 6.7L?A: Yes. This combination kit is designed for all 2007.5-2018 Ram 2500, 3500, 4500, and 5500 models with the 6.7L Cummins diesel, including 2013 model year trucks. Q: Do I need a tuner for this kit?A: The CCV reroute portion typically does not require tuning. However, removing the EGR valve will trigger a Check Engine Light without appropriate ECM tuning. A compatible tuner is recommended. Q: Can I install just the CCV or just the EGR delete?A: Yes, the components can be installed independently. However, installing both together provides maximum intake system protection and is more cost-effective than purchasing separately. Q: Will this improve fuel economy?A: The EGR delete component, when combined with tuning, can improve fuel economy by 1-2 MPG as the engine no longer ingests hot, oxygen-depleted exhaust gas. Q: Is this kit CARB-compliant?A: No. This kit is not CARB-compliant and cannot be sold or used in California or other states adopting CARB standards. For OFF-ROAD / COMPETITION USE ONLY.
