FITMENT

  • 1985–1988 Chevrolet Corvette C4 (5.7L 350 TPI).
  • 1985–1988 Chevrolet Camaro IROC-Z / Z28 (5.0L 305 TPI & 5.7L 350 TPI).

DESCRIPTION

Product Overview

  • Sticking EGR valves and brittle gaskets cause persistent vacuum leaks, rough idles, and erratic performance on 1980s 305 and 350 TPI Corvettes, Camaros, and Firebirds. Decades of exhaust heat create carbon buildup that bakes factory valves open, drawing hot exhaust gases and unmetered air straight into your intake manifold.
  • Clean up your engine bay and restore proper manifold vacuum with this 305/350 TPI EGR Block-Off Plate Package. Designed to bolt directly onto the stock TPI intake manifold, this heavy-duty plate caps open EGR ports, prevents power-robbing vacuum leaks, and helps keep your classic Small Block Chevy running clean and smooth.

Key Features

  • Cut from high-strength billet aluminum with a durable flange that takes engine-bay heat and vibration in stride.
  • Keeps dirty exhaust gases and oily sludge from coating the TPI intake runners and valves, preserving clean airflow.
  • Seals the open runner/base EGR ports to stop vacuum leaks, rough idle, and surging at part throttle.
  • Tidies the engine bay by letting you remove the aging vacuum lines and emissions valves for a cleaner, simpler setup.

FAQ

Q: Is this a full EGR delete or just a partial runner plate kit? 

A: It’s the runner plate portion only — these plates seal the runner-level EGR ports. Depending on your manifold, extra block-off components may be needed for a complete EGR removal.

Q: Where do these plates mount on the TPI intake? 

A: They go onto the factory TPI intake runner/base EGR openings after the original EGR passages are removed or disabled, sealing the now-unused ports.

Q: Can I install this without swapping the intake manifold? 

A: Yes. The plates are made for compatible TPI intake configurations, though access depends on the layout and condition of your specific setup.

Q: Does this kit affect emissions legality? 

A: It’s intended for off-road, competition, or restoration use where EGR removal is permitted. Check local rules before pulling factory emissions hardware from a street-driven car.
