Description
Product Overview
The EGR Delete Kit & Exhaust Cap for 1996-2004 Ford Mustang is purpose-built for the Modular V8 platform that defined the SN95 and New Edge eras. Compatible with 4.6L 2V GT, 4.6L 4V SVT Cobra, and 5.4L GT500 engines, this kit eliminates the Exhaust Gas Recirculation system that introduces hot exhaust gases and carbon deposits into your intake — robbing power, fouling the throttle body, and increasing intake air temperatures. For off-road/competition use only.
Key Features
-
Complete EGR Block-Off Solution: Seals the EGR valve port on the intake manifold, the EGR tube port on the exhaust manifold, and the EGR vacuum port on the throttle body — three-point seal for a clean delete.
-
CNC Billet 6061-T6 Aluminum Plates: Precision-machined block-off plates with laser-cut gaskets — no warping, no exhaust leaks.
-
Steel Exhaust Cap: High-temperature steel cap for the exhaust manifold EGR tube port. Won't crack or leak under sustained exhaust gas temperatures (1,200°F+).
-
Cleaner Intake System: No more exhaust soot and oily carbon deposits coating your throttle body, IAC valve, and intake manifold. Better idle quality and throttle response.
-
Reduced Intake Air Temps: Stopping 500°F+ exhaust gases from entering the intake manifold lowers IATs — critical for supercharged and nitrous applications.

Installation Notes
-
⚠️ Tuning Required: ECU reflash necessary to disable EGR DTCs. SCT X4, DiabloSport, or HP Tuners compatible.
-
⚠️ Off-Road Only: Not emissions-legal for on-road use in the United States.
- Installation time: 2-3 hours with basic hand tools. EGR tube removal on the exhaust manifold requires penetrating oil — these bolts are often seized after 20+ years.
Frequently Asked Questions
Q: Does this require a tune?
A: Yes. Removing the EGR system on 1996-2004 Mustang Modular V8 engines will trigger a check engine light (P0401/P0402). You will need an SCT, DiabloSport, or custom tune to disable EGR-related DTCs. This kit includes hardware only.
Q: Will this fit my 2003 Mustang GT 4.6L?
A: Yes. This kit fits all 1996-2004 Mustang GT (2V), SVT Cobra (4V), and GT500 models with the 4.6L and 5.4L Modular V8 engines. Covers both SN95 (1996-1998) and New Edge (1999-2004) platforms.
Q: What's included in the kit?
A: Includes: EGR valve block-off plate (billet 6061-T6 aluminum), EGR tube exhaust manifold cap (steel), throttle body EGR port cap, all gaskets, and mounting hardware. Complete bolt-on kit.
Q: Is this legal for street use?
A: No. This EGR delete kit is for OFF-ROAD / COMPETITION USE ONLY. Removing emissions equipment from on-road vehicles is prohibited under EPA and CARB regulations. Check local laws before purchasing.
