2004.5-2005 LLY Duramax 4" Cold Air Intake Kit with Air Box
Description
More air for the LLY
This Wehrli kit replaces the restrictive plastic factory intake tube and air box on the 2004.5-2005 LLY with a fabricated 14 ga aluminum tube, a 10 ga aluminum air box and a dry filter.
It pulls cooler air in through the inner fender, and the 4 in. tube with smooth bends raises intake air speed and volume. Wehrli says that means more horsepower and torque, quicker throttle response, cooler intake temperatures and a stronger turbo sound.
The air box lid comes off for an easy look at the filter, and the water-shedding pre-filter helps keep dirt away from the MAF sensor, turbo and engine.
It replaces GM part numbers 19201277, 25345138, 21993711 and 15076901.
Who it's for
LLY owners who want a bolt-on intake upgrade.
