Tek here,
Ive purchased a K&N Filter some time ago and dont remember when your suppossed to clean those things. I know they go alot longer than the regular air filters. Could someone help me out?? Also, where I can get the cleaning kit for a good price. Thanks in advance!
1997 Ford F150 XLT 4.2L V6

 

K&N recommends cleaning performed every 50,000mi. i found that mine had to be cleaned at around 30,000mi. a good price for these? they are all $10 where i look. so its not really worth the time to search for a "good price.

 

I clean mine around 25,000 due to driving in dusty conditions. 50,000 is the recomended cleaning just as jdcfromnyc

most of the time depending on where u live but its good to clean the the filter about every other oil change and clean you MAS and TB every 50K miles

 

Cleaning kits from K&N can be purchased usually from anyone that sells the filters, I purchased mine from Advanced Auto for about $12. I usually clean mine after every oil change, what can it hurt? I would recommend that you make sure the filter is good and dry before applying the filter oil.
