GMC Sierra 2500 Performance Air Intake – Wehrli 4in Intake Kit – Sparkle Copper '06–'07. A high-flow fabricated aluminum intake and air box engineered for the 2006–2007 6.6L Duramax LBZ, finished in a striking Sparkle Copper powder coat.

This system replaces restrictive factory plastic components, significantly increasing airflow to the turbo for improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the inner fender. The all-aluminum 4" piping uses smooth bends to enhance air velocity and volume, and delivers a more assertive engine and turbo note under acceleration. Includes a dry air filter and air box with a removable lid for easy inspection and maintenance, plus a hydrophobic pre-filter cover to help keep the MAF, turbo, and intake tract clean. High-quality hardware, silicone boot, and stainless T-bolt clamps are included. Bolt-on installation with basic hand tools; no tuning required. Made in the USA.
