Description

WCFab 4" Intake Kit with Air Box for 2004.5-2005 LLY 6.6L Duramax equipped Chevrolet Silverado or GMC Sierra 2500 / 3500 HD truck.

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. All new design significantly increases air flow to your turbo producing improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the inner fender. All aluminum construction features large diameter 4" piping with smooth aerodynamic bends to improve intake air velocity, volume, and provide more aggressive engine and turbo sound during acceleration. High quality hardware, silicone boot, seals, and stainless steel t-bolt clamps ensure optimum durability and ease of installation.

Removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with included hydrophobic pre-filter cover, to help keep your MAF sensor, turbo, and engine airways contaminant free.

Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck.

Replaces the following GM part numbers: 19201277, 25345138, 21993711, 15076901

Great product
These are excellent. They work very well and help ensure a good night's sleep without a dry mouth. Ans the taste is good, unlike Berry Smoothie which is absolutely disgusting.

good deal
they work very well - for most of the night. However, cause throat congestion late in the night.

Helps with dry mouth
Scent Name: Berry, Size: 40 Count (Pack of 1)
I purchased this because I’ve noticed as I get older that my mouth produces less saliva. I have been experiencing dry mouth more and more often, especially at night. I started mouth taping and using xylitol melts and I’ve seen a huge improvement in my overall oral health. They are easy to use, taste good and were comfortable overnight. Highly recommend.
