K&N Performance Plus Universal Air Filter Cleaner, Jug, 1 gal, 99-0635

Cleans dirty filters with ease. This container is good if you have multiple vehicles with washable air filters. It strips away grease, grime, and dirt no problem. The included pump sprayer is nice but either remove it or pull the hose completely out after use or it will siphon out the cleaning solution. I wasn't thinking and left the tube in and it peeled up the garage floor epoxy. I would also definitely wear protective gloves when using this cleaner. It is highly alkaline and will strip your hands dry very quickly.

easy to use, helpful to have

K & n cleaner works great getting the filter clean the first try.

Works better than other cleaners on gauze filters. Price is on par with others also.

Works great and is easy to use. Make sure you oil the filter after cleaning it and use grease to seal the joint when you put it back on - failure to do so will result in fine dust in your engine! -m-2014 POLARIS RANGER RZR XP 1000--

This stuff works exactly as designed it cleans out all the old gunk from K&N and other foam type filters. -m-2002 YAMAHA Road Star Silverado XV1600AT--

This stuff works awesome on pleated filters but I also use it on foam filters and anywhere else I need to cut oil, such as the air box. -m-2008 KTM 525 XC--

This is hands down the best filter cleaner for the money. It works great on all of our foam and paper filters.

Pretty easy to use, removes the old oil nicely. One bottle should last a long time.

Great product best stuff yo use for cleaning your filter -m-2015 HONDA CRF450R--
