Wow, thats an eye opener !

 

For warranty purposes I would stick with the stock air filter. Also.....changing the airflow changes fueling which can create soot. Oil/gauze filters can coat sensors causing issues down the road too.

 

You really don't even need the tests to see there's a problem. Just take one of the K&N's off a regular gasser and hold it up to the light.

You'll see tons of tiny holes in the filter ...... and once you see that, it will cure your desire to use a K&N filter.

What is your goal? If it's simply a good filter you want to kep the truck alive, then a stock replacement from Baldwin or AC Delco is your best choice.

But if you're looking for more power or better mileage, you're wasting your money.

 

Save your money. The OEM filter is all you will ever need up to 500 HP. You will gain nothing in MPG or power.
