FITMENT
-
Truck intake manifold EGR and EVAP block off complete kit. For use with all LS truck.
DESCRIPTION
Product Overview
- Factory EGR and EVAP systems on GM 5.3L and 6.0L LS engines are known to recirculate hot exhaust gases and oil contaminants back into your intake manifold. Over time, this causes heavy carbon buildup, chokes airflow, and drags down engine efficiency.
- The LS EGR & EVAP Block Off Plate Kit is the ultimate solution for intake swaps, custom engine builds, and off-road builds. Precision CNC-machined from high-strength billet aluminum, these plates permanently seal unused EGR and EVAP ports—preventing vacuum leaks and delivering a clean.
Key Features
- Precision CNC-machined from high-grade aluminum to easily withstand extreme engine temperatures, heavy vibration, and harsh under-hood environments.
- Safely seals redundant EGR and EVAP passages—making it an essential upgrade for engine swaps, aftermarket intake upgrades, and off-road builds.
- Equipped with heat-resistant gaskets and heavy-duty hardware to deliver a rock-solid, airtight fit that prevents frustrating vacuum or exhaust leaks.
- Engineered to fit stock GM LS truck intake and exhaust manifolds equipped with EGR/EVAP ports, as well as a wide range of compatible aftermarket intakes.
FAQ
Q: Why is an EGR & EVAP delete kit necessary for an LS engine swap or build?
A: When performing an LS swap or installing an aftermarket intake, stock EGR tubes and EVAP purge valves are typically removed. This complete kit caps off all open intake and exhaust ports, ensuring a leak-free seal and giving your engine bay a clean, uncluttered look.
Q: Do I need to remove the intake manifold to install this block-off kit?
A: In most setups, full intake removal isn't required. However, depending on your engine bay clearance and surrounding accessories, removing a few nearby components may make accessing the ports much easier during installation.
Q: What should I do with the remaining EGR/EVAP wiring harnesses after installation?
A: You can neatly tuck away or cap off the factory connectors. Please note that if you are running a stock GM PCM, an ECU tune (or recalibration using software like HP Tuners) will be required to disable the related Diagnostic Trouble Codes (DTCs) and check engine lights.
Q: How will installing this block-off kit affect my engine’s performance?
A: While the kit itself doesn't directly add horsepower, it protects your engine by preventing dangerous vacuum and exhaust leaks. It maintains stable intake pressure, stops hot exhaust gas recirculation, and ensures your LS runs cleanly and reliably.
