L5P Duramax EGR Valve Cooler Delete Kit Overview 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. Key Features of This L5P EGR Delete Kit High-Quality Materials and Design: Made from durable materials, this kit ensures long-lasting performance. The design is tailored specifically for the L5P Duramax engine, ensuring a perfect fit. Performance Enhancements: By removing the EGR system, this kit helps your engine run more efficiently, leading to improved power and torque. Ease of Installation: Designed with the DIY mechanic in mind, this kit comes with clear instructions, making installation straightforward. Eliminating the EGR system will prevent soot from building up and clogging the EGR valve. Instead of hot exhaust gas being re-routed into the intake, fresh dense clean air can now circulate. Improved exhaust flow allows the turbocharger to spool up faster which results in quicker throttle response. This EGR delete is engineered and designed to recirculate engine coolant faster and more efficiently then the stock EGR system. High quality components consist of billet aluminum construction, nickel plated steel flanges, stainless steel dipstick tube bracket, high temp silicone hoses, zinc coated hardware & precision fit o-rings. Everything needed for a complete install is included. Installation takes approx. 2hrs with basic hand tools. When installing an EGR delete: a DPF delete...
