Depending on conditions and usage the water repellent treatment is good for 1 to 2 years.

Warranty Information

K&N O/E Replacement Air Filters and Air Intake Systems purchased from Authorized Dealers are backed by a Million Mile Limited Warranty when used primarily on paved roads and on vehicles for which they were designed. If one of these products ever fails to provide complete satisfaction, K&N will replace it.

K&N Aftermarket Air Filters should be cleaned every 50,000 miles for normal highway use, more often in dusty conditions. Cleaning should be done with K&N cleaner and air filter oil (or comparable air filter cleaner and oil). Use of compressed air, or chemicals not specifically designed to clean and re-oil cotton air filters (i.e. gasoline, transmission fluid, motor oil, lightweight oil, or diesel fuel) will void the warranty. Any damaged, abused or modified K&N Air Filters will not be warranted.

K&N wants to make sure that when you buy a K&N Lifetime Air Filter or Air Intake System, you can be confident your vehicle's warranty will not be impacted. K&N also want you to feel confident that even if you experience difficulties with a dealership repair department, K&N will step-in and resolve the issue, so you won't have to. Therefore, K&N makes the following Pledge: K&N pledges to their customers that they will not be taken advantage of and charged for a repair due to a manufacturer warranty denial blamed on the presence of a K&N product.

Magnuson-Moss Warranty Act:
Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)) Learn More

K&N Drycharger
I bought this as a safety precaution for my cold air intake. It arrived on-time, has great quality and fits perfectly around my K&N filter. Material is fin and tough and should be a great barrier for the filter over the years.

Looks Great!
Wasn't too sure I needed this but, I'm glad I did. I've had several K&N Air Filters and always had problems getting the bugs out of them. This will fix that problem and make the filter last a lot longer.

Easy To Use
Still waiting for my first really wet weather to see how well it works. But with my experience with other k&n products I don't think I will be disappointed.

Wait And See
Purchased based on product description. Glad i did once i installed the K&N air intake as the bottom on the wheel well had a direct open space to the ground, so "if" it does what is says it does will serve a great purpose. Just will not know until I have to deal with a rain storm and see how it works. Did take a little effort to get into place correctly.

Good Addittion to CAI
Worth the money because it adds an extra layer of protection just in case anything happens. Wouldn't hesitate to purchase this in addition with a KN CAI.
