Why you change your air filters

rarwz · 03-20-2011, 10:56 AM

25,000 miles in, I switched out my stock filters (30k life) for K&N.

Just wanted to post a few pictures of the old filters and dirty they were. Its quite interesting to see what made it up the intakes into the filters.

Interesting to see where most of the airflow goes.

Somehow a pebble got stuck in the filter. A pebble made it all the way to there. Wow.

Lots of seeds and other misc stuff stuck in there.

Compared to my last car (corolla) this is crazyness, as there was never anything more than a 'helicopter' seed or two in there in 100k+ miles.

Your Corolla didn't need nearly the volume of air that a 3.7 liter, 332hp engine needs. The vacuum that pulls through the intakes is pretty intense.

That's a lot of crap up in the filters.

Wonder whatdamage a pebble could have done to the engine.

That's why the filters are there

I noticed better mileage from adding the K&N man, mileage went up to 16.2mpg in just a few days

Doing this next man? Intake Tubes
