NEVER put a K&N on your truck...... Anything else is fine, but really your good to go with the stock one.

Airaid makes a air filter replacement for your truck.....I just got one myself..

6.0...best filter at any price is the stock one period.

The stock filter actually filters better than the K&N in our trucks. Remember your turbo is right behind the air filter. Do you really want to dust your turbo? I didn't think so...

How do you know when it is time to replace your stock filter with a new $76 stock filter? I have 58,000 miles on my stock filter.
