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- Plugs the unused emissions ports to clean up vacuum routing, retire outdated parts, and leave a tidier engine bay.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: What plates are included in this complete Toyota EGR & Smog block-off kit?
A: The kit contains all plates required to seal your engine ports, typically including 2 x Exhaust Manifold Plates, 1 x Rear Cylinder Head/EGR Plate, and 1 x Intake Plenum / EFI Plate.
Q: Do I need to use gasket sealant when installing these block-off plates?
A: While you can reuse factory gaskets if they are in good condition, applying a thin, even layer of Ultra-Gray or High-Temp RTV silicone gasket maker to all mating surfaces is recommended for an airtight, leak-free seal.
Q: What should I do with the remaining vacuum lines after removing the EGR valve and air pump?
A: Trace and cap off all open vacuum ports on the intake manifold and carburetor using rubber vacuum caps. Leaving vacuum ports open will cause a lean air-fuel mixture, high idle, and severe engine misfires.
Q: How do I prevent the Check Engine Light on fuel-injected 22RE / 22RET engines?
A: EFI 22RE and 22RET engines equipped with a factory EGR Temperature Sensor will trigger a fault code if the sensor is unplugged. Inserting a 10k Ohm (or 5.6k Ohm) 1/4-watt resistor into the factory sensor wiring harness pigtail bypasses the sensor signal and keeps the CEL off.
