Old man is in Iraq - took a peek under the hood to see what kind of aftermarket stuff he had on his 97 F250 Light Heavy Duty, and I don't think this filter has EVER been cleaned! So I got the kit, but now I'm paranoid about getting all the excess oil off after re-oiling it. I'd really rather fry the sensor and have to blow $300.
What do you guys think? Get a new, better filter? (I've never been a K&N fan, anyway.)
