  • what is a recharged k&n ai filter?do you have to reoil the k&n air filter if so what do you use!what happens if you dont

  • @mossow71 most autoparts stores sell the K&N Recharge kit.the kit comes with the cleaning solution and special oil for K&N filters.the oil that is put on filters is what catches the small dirt particles.

  • im running the stock filter. K&N lets in too much dirt. theres where the "more air flow" comes in...........

  • @Matt06yfz alone the K7N will block the same amount of dirt as a stock filter if it is properly oiled.i myself added the K&N filter lid for added filtration and to get the air box lid removed effect without the risk of added dirt getting into my box.

  • I finally got my K&N air filter today. I may do an unbox and install vid. The instructions didn't say anything about oiling it. Did yours come pre-oiled? It looks and smells like it could be already lubed up.

  • @jarreau2001 if the filter is a red color that means it is already oiled.usually all K&N filters come preoiled.

  • I would use fuel customs. Its a 8 ply filter way better keeping mud and water out. I also use the prefilter. I also run the fuel customs intake. What a huge difference in power.

  • What style/size does the 04 yfz 450 use, and how do I rejet when I do install it?

  • Just fitted a k & n panel filter to my wifes small 1.6 automatic Nissan Note. Cost £42, priced up air filter with Nissan £20. The difference is huge, old filter was grubby so any filter would have made a big difference. Seems much more smooth through the gears & not tested long enough but im almost certain that the increased mpg will pay for itself. Also will not need to clean for long time. No increase in performance/bhp but was not bought for that, just for economy.

  • i have a k&n airfilter and a slip on pipe..its jetted right without the airbox lid...now if i buy the ai filter lid to i have to rejet again?

  • @Tooextrememx see u r doing it the smart way, added filtration and always oiled. Most people probably do neither. my local dealership told me to get rid of the K&N for a stock filter. i might switch to a UNI, no air box lid and an HMF Comp series slip on. i mostly ride on a dry field and lakes (in the winter of corse). hopefully ill get some good gains from that!

  • @Tooextrememx

    Yeah it's red. Thanx!
