Good tips! I wouldn't want to run anything over the pleats though for fear of damaging the screen/cotton. Save yourself the time and only oil the unfiltered air side. The cotton will wick the oil up to saturate the whole filter. Oiling the clean air side opens an opportunity to have excess oil come off and gum up the air sensor. It just takes a little longer to wait for the oil to migrate over the entire filter.

spray cleaner on dirty side, wait 10 mins, rinse with water flowing from clean side through to dirty side to flush out dirt and cleaner put air filter oil on the "dirty side" along each pleat and it soaks in. essentially avoid touching the "clean side" if you can help it

Great video, I bought a spare filter for my VCM OTR, so I always have a clean filter to slap in at service time

great tutorial and walk through

Don’t u need to wait 10 min before rinsing

I've been using compressed air for years, just be smart about it - ~50psi with a vented nozzle and follow-up drying in the sun. For those that don't know, Metho = Denatured/99% Isopropyl alcohol in the states. Also, don't waste that much degreaser - coat it on both sides and flush after 5min. Simple Green and Formula 409 are much more cost-effective alternatives to the K&N brand cleaner, and they clean as well...if not better/faster.

I recently bought my K&N filter and installed it straight outta the box as it says pre oiled. Do I need to add more oil at all or just change/clean it every 15k miles?

[@OEMDeniedPerformance]

pre oiled straight out the box so just clean and re oil next service or when it starts to look dirty

Nice video Mate but unfortunately the K&N filter does nothing to save me any fuel or make a difference in my 2014 F-150 truck performance. I can't wait to finish the cleaning and oil product so I can put the filter in the garbage.

At no point do I say that a K&N air filter will save any fuel or alter performance. Its an instructional video on cleaning. The benefit of a K&N filter is it can be cleaned and reused instead of being thrown into bin.

It says not to do both sides in the instructions. Shit is stressing me out lol

@@taylorpelletier89 1/4 down K&N website "If oiling a K&N air filter using the air filter oil aerosol spray, the process is similar to using the squeeze bottle kit. Spray the oil evenly along the crown of each pleat, holding the spray nozzle about 3" away from the filter. Allow the oil to wick for approximately 20 minutes. Touch up any light areas on either side of the filter until there is a uniform red color in all areas" So dont stress :) www.knfilters.com/blog/ask-the-experts-at-kn-how-to-use-kn-air-filter-oil-how-much-oil-do-i-use/

@@taylorpelletier89this is my problem, K&n really doesn’t specify clearly on the instructions which side to oil, but I’ve seen videos that show either the air in side or both.
