CCV Reroute Kit

The Spelab CCV Reroute/Delete Kit is engineered to enhance the reliability of the L5P 6.6L Duramax engine's crankcase ventilation system. The factory CCV system is prone to cracking over time and can allow hot charge air from the turbo to enter the intake air horn. This kit addresses these issues by rerouting or deleting the system, leading to improved engine performance and reduced oil contamination. This kit is specifically designed for 2017-2024 L5P 6.6L Duramax Diesel GMC Sierra 2500HD/3500HD and Chevrolet Silverado 2500HD/3500HD models. It is compatible with Crew Cab short bed and Crew Cab long bed configurations. However, it explicitly will not fit the 3500/4500/5500 Cab&Chassis commercial style trucks. The kit features durable materials and is designed for easy installation, typically taking 1-2 hours with standard automotive tools. No ECU tuning is required, and the factory intake configuration remains unaffected. Benefits include reduced oil contamination, improved engine performance, and potentially better fuel economy due to increased engine efficiency. A 12-month warranty is included. While the installation is straightforward, customer feedback suggests specific security screws may require a T40 bit and hammering to remove. Some users also noted that the included elbow fitting might kink the hose, recommending alternatives for a smoother flow path. It is important to note that installing this kit may affect certain aspects of your vehicle's warranty.
