TruckTok 5.3L 6.0L LSX Silverado LS Truck LQ4 LQ9 EGR Tube Plug Intake Block-off Plate

FITMENT

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

DESCRIPTION

Product Overview

• GM LS-series engines (5.3L and 6.0L) equipped with factory EGR and EVAP systems can recirculate hot exhaust gases and contaminants into the intake. Over time, this can contribute to carbon buildup, reduced airflow, and decreased engine efficiency.
  
• The LS EGR & EVAP Block Off Plate Kit provides a clean solution for intake swaps, engine conversions, and off-road builds. Made from precision-machined billet aluminum, these plates seal unused EGR and EVAP ports to simplify the engine bay and prevent unwanted leaks.
  

Key Features

• Precision CNC Billet Aluminum: Machined from high-strength billet aluminum for durability against engine bay heat and corrosion.
• Uses Factory Mounting Hardware: Designed to work with OEM intake manifold retaining plates and bolts for a simple installation.
  
• Pre-Installed High-Temp: Features a recessed groove with a heat-resistant silicone O-ring for a reliable vacuum seal without RTV or liquid sealants.
  
• Prevents Vacuum Leaks: Seals the intake manifold EGR port to eliminate unused openings and maintain proper intake sealing.
  
• Clean Engine Bay Design: Removes unused EGR tubes and vacuum lines for a cleaner, simplified LS engine compartment.

FAQ

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

A: This plate caps only the intake port. To fully seal your system, you also need plates for the exhaust manifold and EVAP solenoid. check out LS EGR & EVAP Baffle Kit.

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

A:  No. The plate includes a pre-installed high-temperature silicone O-ring in a precision groove for a reliable vacuum seal without RTV or liquid sealants.

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

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