WCFab Stage 2 4in. Cold Air Intake Kit for Select 2020-2025 Chevrolet/GMC (6.6L) - Candy Teal
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2020-2025 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD trucks (6.6L Duramax L5P).
The WCFab Stage 2 4-inch Intake Kit replaces the restrictive factory plastic induction system with a high-flow fabricated aluminum assembly. This kit features a 4-inch diameter intake pipe and an oversized intake horn that is over an inch larger than the OEM diameter, significantly reducing restriction at the turbo inlet. The included 10G aluminum air box and lid are designed to seal against the factory functional hood ram air port and inner fender, ensuring the engine draws in the coolest possible air for improved throttle response, increased horsepower, and lower intake temperatures.
- 4" fabricated aluminum intake pipe with smooth aerodynamic bends
- Oversized 4" intake horn to maximize air velocity at the turbo
- 10G aluminum sheet metal air box and lid
- High-flow dry air filter with Outerwears pre-filter cover
- Heavy-duty silicone boot and stainless steel T-bolt clamps
- Durable Candy Teal powder coat finish
