In wet, muddy, or dusty conditions, some extra filter protection can help provide peace of mind, and can also help increase time between filter cleanings. K&N® filter wraps and pre-filters help keep water and particles away from your filter—so you can enjoy the benefits of your high-performance K&N® air filter even under rigorous conditions.

It all began with motorcycles back in 1969, when Ken Johnson and Norm McDonald created the original oiled High-Flow Air Filter™ for their off-road bikes. Since that time, K&N® has continued to develop cutting-edge performance products for motorcycles, and offers intake systems for dozens of Harley-Davidson motorcycle models and years including newer Fat Boy, Softail, Road Glide, Street Glide, Road King, and Electra Glide models.

K&N has brand new intakes hot off the production line for 2019-2021 RAM 2500/3500 diesels, as well as multiple options for previous model years. If you have a 2500 or 3500, this is one performance upgrade that might be hard to pass up—and we think your right foot will thank you.

K&N offers performance oil filters designed for automotive, motorcycle, marine, and heavy-duty applications. Read on to learn about our precision-engineered filters, and to find the best K&N oil filter for you. Let us help take the guesswork out of your next oil change.
