K&N for your Duramax

Works great, looks great, very easy to install. Lets the beast breathe through a couple of mountain passes and nearly 2,000 miles while towing a 7,000-pound trailer.

Pros
  • Air Intake
Cons
  • Hard to say

Cheap Performance Upgrade

Bought for my 2004 Silverado 2500HD. The engine breathes much better. Fuel economy increased by 2.5mpg. It pays for itself in about 2 months if diesel fuel does not increase sharply in price, in which case it pays for itself in 1 month. Excellent delivery. For now.

Pros
  • Auto
Cons
  • Vulgarity

04 Duramax fits Filter

Received quickly for a fee Scratches on the chrome and the side of the filter was a bit bent at the end but I didn't want to bother with sending it back and blah blah so I just pushed it a bit more and it got a good seal - to be honest in my 2004 Duramax the only thing I hear more is the turbo - I thought I heard more intake like my N/A machines but overall I'm happy

Pros
  • Filter
Cons
  • Discontinued
