Why Choose iFJF
Classic Ford owners know the struggle — a sticky EGR valve causing rough idle and hesitation that's often misdiagnosed as a vacuum leak or bad IAC. iFJF's billet block-off plate eliminates the problem permanently. Whether you're building a Fox Body track car or refreshing an OBS F150, this is the clean solution.
Installation Instructions
-
Locate EGR valve — On the 5.0L, it's on the passenger side of the upper intake plenum near the throttle body. On the 4.9L I6, it's on the intake manifold near cylinder #1.
-
Remove EGR valve — Two bolts and a vacuum line. The EGR tube runs to the passenger-side exhaust manifold — remove this as well.
-
Clean manifold surface — Scrape old gasket residue. Use brake cleaner on a rag — don't spray directly into the open intake port.
-
Install block-off plate — Position gasket, then plate. Insert bolts, hand-tighten, then torque to 15 ft-lbs.
-
Plug the vacuum line — Cap the EGR vacuum source port to avoid a vacuum leak. Reconnect battery.
Frequently Asked Questions
Q: What Ford engines does this EGR delete plate fit?
A: This kit fits the Ford small-block V8 engines: 2.8L V6 (Cologne), 4.9L (300 I6), and 5.0L (302) V8 found in 1979-1995 Mustang, 1980-1996 Bronco, and F-Series trucks.
Q: Is this compatible with the 5.0L HO engine in the Fox Body Mustang?
A: Yes. The EGR mounting pattern is the same for the standard 5.0L and the High Output (HO) version used in 1987-1993 Mustang GT and LX 5.0.
Q: What's included in the kit?
A: Block-off plate for the intake manifold EGR port, high-temperature gasket, and mounting hardware. For the exhaust side, the EGR tube must be plugged or removed separately.
Q: Will I lose power by deleting EGR on my 5.0?
A: No — the EGR system only operates at part-throttle cruise. At wide-open throttle, EGR is already closed by the ECU. Deleting it primarily improves idle quality and reduces intake carbon buildup.
Q: Is this for off-road use only?
A: Yes. EGR system removal is not EPA-compliant for on-road vehicles. This product is intended for off-road, racing, and competition applications only.
