K&N drop in filters

after how many km aprox. should those filters be cleaned with the recharge kit? (driving in normal street conditions)

Like...probably never lol. I cleaned mine 1 time b/c it was so dusty I coudn't tell what it was anymore. I think the box said like 30K or something..I'm probably wrong though.

Once a year I clean everything:

Clean K&N air filter
Replace coolant
Flush engine
Replace brake fluid
Grease everything even the hub bearing / u-joints
Change diff oil
Dump tranmission fluid and put in new fluid
B-12 the trottle body.

Twice a year I replace mobile one oil filter and oil.


I did have one side effect taking care of a car this much.

I got 17 years and 350,000 miles out of a Ford F-150 and it still does not burn oil but my g*d it is ugly looking compare to my new 2000 - 3500.



So it is your call. I keep it clean because I can tell the difference between a clean air filter and a dirty one.

good system you got there gschetter. I'll prob follow some sort of schedule like that for mine. It's good to see people that take car of their vehicle like that.

B-12 the trottle body.


What's B-12?

Throttle Body cleaner.
