Description
EGR Simulator & Block Off Plate for 1986-1995 Ford
Complete EGR elimination solution for 1986-1995 Ford F-150, F-250, Bronco, and Mustang with 2.8L, 4.9L (300 I6), or 5.0L (302) engines. This kit includes a CNC-machined billet aluminum block off plate to physically seal the EGR port, plus an EGR simulator that plugs into the factory wiring harness to prevent the check engine light while keeping the CEL functional for other diagnostic codes. Intended for off-road and competition use only.
Key Features
-
CNC Billet 6061-T6 Aluminum Plate — Precision machined from aircraft-grade aluminum. Won't warp or deform like thinner stamped steel delete plates.
-
Factory-Locking Connector EGR Simulator — Plugs directly into the stock EGR wiring harness. Provides the ECU with a closed EGR status, preventing the check engine light for EGR codes — while leaving the CEL fully functional for all other diagnostic trouble codes.
-
Not an EGR Defeat Device — The simulator reports a valid EGR position to the ECU. The check engine light remains active and will illuminate for any non-EGR fault.
-
Complete Kit — Includes billet aluminum block off plate, EGR simulator module, gasket, and mounting hardware.
-
Cleaner Intake — Eliminates carbon buildup from exhaust gas recirculation in the intake manifold and throttle body.

Why Choose iFJF?
The factory EGR system routes hot exhaust gas back into your intake — clogging the manifold with carbon, reducing throttle response, and adding complexity unnecessary for off-road and competition use. Our block off plate physically seals the port while the simulator keeps your ECU happy and your CEL useful for real problems. CNC machined from 6061-T6 billet. For off-road / competition use only.
Just Need the Simulator?
If your engine is a 5.8L/351W or 7.5L/460 (not covered by this plate kit), or you only need the electronic EGR bypass, check out our standalone EGR Delete Simulator — same plug-and-play install, covers all 2.8L-7.5L engines.
Frequently Asked Questions
Q: Will this trigger a check engine light?
A: No — the included EGR simulator plugs into the factory harness and reports a closed EGR valve status to the ECU. The CEL remains fully functional for all other diagnostic trouble codes.
Q: Is EGR delete legal for street use?
A: This product is for OFF-ROAD / COMPETITION USE ONLY. Removing emissions equipment on public roads is prohibited under EPA regulations. Check your local laws.
Q: What's the difference from a plain block off plate?
A: A plain block off plate alone triggers a persistent check engine light. Our kit includes a simulator that keeps the CEL off while maintaining full diagnostic capability.
Q: Do I need a tune after installing?
A: No ECU tuning required for 1986-1995 OBD-I Ford vehicles. The simulator handles the EGR signal. Some owners report smoother idle and improved throttle response.
Q: Will this fit 5.8L/351W engines?
A: No. This kit is for 2.8L V6, 4.9L I6, and 5.0L V8. Contact us for 5.8L/351W fitment.
Q: How difficult is installation?
A: Moderate. Remove EGR valve (2 bolts), clean surface, install plate with gasket, plug in simulator. Basic hand tools. 30-60 minutes.
