FITMENT
- Toyota 20R, 22R (Carb), 22RE (EFI) & 22RET (Turbo) 2.4L L4 engine.
DESCRIPTION
Product Overview
-
Decades of heat and vibration cause original EGR valves, air-injection reed valves, and brittle vacuum lines on classic Toyota 2.4L 22R (carbureted) and 22RE (EFI) engines to fail. Warped air-injection manifolds and leaking EGR seats draw unmetered air into intake runners—triggering lean misfires, erratic surging idles, and severe power drop-off under load.
- Engineered for full vacuum and exhaust circuit isolation, this Toyota 22R/22RE EGR & Smog Block-Off Plate Set permanently caps off all factory emissions ports. Machined to seal flat against the cylinder head and intake manifold, it eliminates unmetered vacuum leak points, prevents exhaust back-feeding into the intake, and streamlines your classic engine bay for effortless maintenance.
Key Features
- High-strength aluminum alloy stands up to engine heat, vibration, and years of use.
- Plugs the unused emissions ports to clean up vacuum routing, retire outdated parts, and leave a tidier engine bay.
- Goes on with a simple bolt-on, precision-fit design that’s easy to fit and just as easy to remove when servicing.
- Made for classic Toyota 20R, 22R, 22RE, and 22RET engines in pickups, 4Runners, and Celicas.
FAQ
Q: EGR delete vs. Smog/Air Injection delete — what’s the difference?
A: The EGR side feeds exhaust gas back into the intake; the Smog/Air Injection side sends fresh air into the exhaust manifold. Two different systems, two different ports.
Q: Should I plug the leftover vacuum lines after installing?
A: Yes — plug every unused vacuum port after pulling the EGR or smog parts, or you’ll chase leaks and the engine won’t run right.
Q: Where on the engine do these block-off plates actually mount?
A: It depends on how your engine is configured. The plates are made to seal the factory EGR and air injection ports on the matching intake, exhaust, and cylinder head pieces.
Q: Does deleting the EGR change how the engine runs?
A: The kit’s real purpose is sealing unused emissions ports and tidying up the engine bay. If a worn EGR system was behind leaks or drivability problems, getting a proper seal can help bring normal running back.
