Swap the intake in your GM 6.6L Duramax today with Wehrli Custom Fab WCF100192-SGB 4" Intake Kit W/Air Box Semi-Gloss Blk from GAP. This high-flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts on your diesel for improved engine performance. This design significantly increases airflow to your turbo producing improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the inner fender.

High-quality hardware, silicone boot, seals, and stainless-steel t-bolt clamps ensure optimum durability and ease of installation. The removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with an included hydrophobic pre-filter cover, to help keep your MAF sensor, turbo, and engine airways contaminant-free.

Very disappointing.

love the shirt and they fit well for an overweight man. All the ones I got are consistent in size and you don't see that often.

Excellent style and quality for price
Color: Grey Blue, Size: Medium
Very nice quality and affordable price. Fabric is soft and smooth, very few wrinkles after washing and drying and easy to iron. Seems durable for machine washing and drying. Fits true to size.
