Description

SPELAB carefully designed and manufactured EGR delete kit features a material upgrade, using solid carbon steel instead of the previous aluminum alloy.

This change has increased the maximum temperature resistance from 600 degrees Celsius to 1,500 degrees Celsius, a 2.5-fold increase in high-temperature strength. This unit effectively prevents soot buildup and EGR valve clogging, allowing fresh, dense clean air to circulate instead of reintroducing hot exhaust gases.

Improved exhaust flow enables the turbocharger to start faster, resulting in quicker throttle response. High-quality components include billet aluminum construction, nickel-plated steel flanges, a stainless steel dipstick tube bracket, high-temperature silicone hoses, zinc-plated hardware, and precision-fit O-rings.

This kit mounts to the exhaust port and flows coolant through a rubber hose for better oil resistance.
The L5P Duramax EGR Delete Kit is an essential upgrade for your Duramax engine. This kit helps improve your truck's reliability by removing the EGR valve and cooler. By doing so, you prevent soot buildup and improve your engine's efficiency.
