Description
Product Overview
The iFJF EGR Delete Block Off Plate Kit is engineered for 1983-1997 Ford F-Series trucks and Broncos with the 5.0L (302) or 5.8L (351W) V8 engines. CNC-machined from 6061-T6 billet aluminum, these plates permanently seal the EGR ports on both the intake and exhaust manifolds. ⚠️ For off-road and competition use only — not street legal in emissions-controlled areas.
Key Features
-
CNC-Machined Billet Aluminum — Precision-cut 6061-T6 aluminum plates with a smooth sealing surface. Won't warp or crack like stamped steel alternatives.
-
Complete Kit — Includes intake manifold block-off plate, exhaust manifold block-off plate, high-temperature graphite gaskets, and Grade 8 hardware.
-
Eliminates Carbon Buildup — Removing the EGR system stops exhaust soot from entering your intake manifold, keeping intake ports and valves clean.
-
Improved Throttle Response — Cleaner intake air charge = crisper throttle and more consistent idle quality.
-
Corrosion-Resistant — Natural aluminum finish with protective clear anodizing. Won't rust like steel plates.

Why Choose iFJF
Generic EGR block-off kits often use thin stamped steel that warps and leaks. Our CNC-machined billet aluminum plates maintain a true flat surface for a leak-free seal. Every kit includes high-temperature graphite gaskets — not cheap paper gaskets that burn through after a few heat cycles. Designed by enthusiasts, for enthusiasts.
Installation Instructions
-
Disconnect the battery and allow the engine to cool completely.
-
Locate the EGR valve — mounted on or near the intake manifold on the passenger side of the engine.
-
Remove the EGR valve — disconnect vacuum line, unbolt from the intake manifold. Remove the EGR tube running to the exhaust manifold.
-
Clean the mounting surfaces — use a gasket scraper and brake cleaner to remove old gasket material and carbon deposits.
-
Install block-off plates — place the graphite gasket between the plate and manifold surface. Hand-tighten bolts, then torque to 15-18 ft-lbs in a cross pattern.
-
Cap vacuum lines — plug any open vacuum ports left by the EGR system removal.
Frequently Asked Questions
Q: What is an EGR delete and why would I do it?
A: EGR (Exhaust Gas Recirculation) routes exhaust back into the intake to reduce emissions. Over time, carbon buildup clogs the EGR valve and intake passages, causing rough idle, poor performance, and reduced fuel economy. Deleting it cleans up the intake path for improved throttle response — for off-road and competition use only.
Q: Does this kit include everything I need?
A: Yes. The kit includes aluminum block-off plates for both the intake manifold port and exhaust manifold port, plus high-temperature gaskets and Grade 8 hardware. Everything needed for a complete installation.
Q: Will this trigger a check engine light?
A: On OBD-I vehicles (pre-1996), typically no. On 1996-1997 OBD-II vehicles, removing the EGR system may trigger a P0401 code. This kit is intended for off-road use where emissions compliance is not required.
Q: Does this fit the 5.0L and 5.8L?
A: Yes. The plate pattern fits both the 5.0L (302) and 5.8L (351W) Windsor V8 engines found in 1983-1997 Ford trucks and Broncos. Always verify your EGR valve mounting pattern before ordering.
Q: Is this for diesel or gas engines?
A: This kit is for the GASOLINE 5.0L/5.8L V8 engines. Not for diesel applications. For 6.4L Powerstroke diesel EGR delete, see our separate diesel kit.
