This is a much worse problem with oiled foam filters than oiled gauze. Foam can hold much more oil and it can seep out for weeks or months. A properly oiled K&N filter has never harmed any sensors or caused any problems according to K&N. Manufacturers cannot void your warranty for using a K&N filter. The only possible problem comes when a K&N filter is over oiled. Some of the excess oil can get in the air stream and contaminate the MAF sensor or other sensors downstream. What about manufacturer’s claims that the warranty is void? I recommend to my customers that they clean and re-oil at least once a year, or check it every 30,000 miles. If you drive on a lot of dirt roads, or race on dirt, then you may be cleaning your filter much more often. In that case, consider a K&N “Precharger” filter wrap to keep out the biggest dirt chunks and cut down on how often you have to clean. The old drop light held behind the filter is NOT a very good test, but for sure, if you can’t see light through your filter, it should be cleaned. But without this, you can pretty much see if the filter is getting plugged up. The best way is to use an air restriction gauge like most bigger diesel trucks have. If you divide 1,000,000 by 40,000, you get 25….works out pretty nice doesn’t it! How do I know when to clean my filter? They also says that you should not clean your filter more than 25 times or the cotton filter media can become to worn to filter effectively. K&N says their filter will go up to 40,000 or more miles before needing cleaning. K&N has a “ Million Mile Warranty” or basically for the life of your vehicle. Step 3: Reinstall the air filter back into your car.Ĭheck Price at Amazon FAQs How long will the K&N filter last?

Again, take extra care to never wipe on or pull at the cotton filter material. Some drops of oil can stay on the wire mesh, and you don’t really need this oil to be there. I like to take a lint-free cloth or one of those Scott blue shop towel (paper towels) and lightly pat the filter and wipe off the seal area. Step 2: Wait at least 10 minutes and touch up any spots that are still white.The entire filter should have a light red color.ĭO NOT OIL THE ENTIRE FILTER TWICE! Only touch up white spots. NOTE that the spray oil comes out in a sputtering stream rather than a fan spray, like paint. Step 1: Hold the can two -three inches from the filter and spray across the top of one pleat onto the side of the next pleat and put one quick line of oil on each pleat. Put one thin line of oil on each pleat, only on one side please. Remember you are oiling the OUTSIDE of the filter, the way air goes into the filter. K&N oil comes two ways, a squeeze bottle of oil or a spray can. I clean my filters either in the evening so they can dry overnight, or when I start a day-long detail session. When the next day dawns or the detail is over, the filter is ready to oil.ĭO NOT use compressed air or heating elements to speed the drying process. Step 5: Shake the filter to remove excess water and set aside to dry naturally. Most hoses for car washing have way too much pressure, turn down the pressure to a gentle stream. NEVER use high pressure AIR or WATER. I use the kitchen sink most of the time. Step 4: Then use a gentle stream of water from the back side (opposite of air flow) to rinse it out. Step 3: After soaking the element, let it sit for about 10 minutes. I like that K&N makes their cleaning/re-oiling kits very affordable, they don’t try to make these products a profit center. It is cheap enough that there is no excuse for using anything else. It is very inexpensive and the only product guaranteed to properly clean your K&N filter and not damage the cotton fibers. Step 2: Spray both side of the filter with K&N cleaner. Step 1: Carefully remove the air filter from the stock air box or from the end of the intake system.
