FITMENT

  • Truck intake manifold EGR and EVAP block off complete kit. For use with all LS truck.

DESCRIPTION

Product Overview

  • Factory GM 5.3L and 6.0L LS engines utilizing stock EGR and EVAP hardware are prone to carbon contamination and heat transfer within the intake manifold. Recirculated exhaust gases and fuel vapors dump abrasive carbon deposits into intake ports, coating throttle passages and degrading overall charge-air density over time.
  • Precision-engineered for engine swaps, aftermarket intake upgrades, and dedicated off-road builds, this LS EGR & EVAP Block Off Plate Kit permanently seals vacant intake and exhaust ports. CNC-machined from high-grade billet aluminum with flat-mating tolerances, it eliminates potential vacuum leaks, cleans up engine bay plumbing, and safeguards the intake tract against power-robbing carbon sludge.

Key Features

  • Crafted from high-strength billet aluminum to withstand extreme engine heat and resist corrosion for long-lasting durability.
  • Engineered to retain your factory intake manifold plates and hardware—no extra parts or custom modifications needed.
  • Features a custom recessed groove with a high-temperature silicone O-ring, delivering a leak-free vacuum seal without messy RTV sealants.
  • Completely caps off the unused intake manifold EGR port to maintain consistent engine pressure and optimal seal integrity.
  • Easily declutters your LS engine compartment by eliminating unnecessary EGR hoses, lines, and bulky hardware.

FAQ

Q: Does this item include the mounting bracket or bolts?

A: No, this is a single block-off plate. It caps only the intake port and is secured using the factory retaining bracket and bolt — no separate mounting bracket is included in the kit.

Q: Do I need gasket maker or silicone sealant during installation?

A: No. The plate ships with a pre-installed high-temperature silicone O-ring set in a precision groove, giving you a reliable vacuum seal without RTV or any liquid sealant.

Q: Where does this intake block-off plate install on my LS engine?

A: It mounts on the factory EGR tube port on the LS truck intake manifold. Remove the OEM EGR tube, press the billet block-off plug into the port, and secure it with the factory retaining bracket and bolt.

Q: Which other plates do I need to completely remove the EGR/EVAP system?

A: For a complete delete in one pass, grab the  EGR & EVAP block-off kit, which covers the intake, exhaust, and EVAP ports together.
