The power of durability, mile after mile


Unlike disposable filters which must be frequently replaced, E-0646 K&N® High-Flow Air Filters™ are washable, reusable, and engineered to last for the life of your vehicle. Feel confident in your purchase with a "No-Hassle" Lifetime Limited Warranty.
Originally designed for high-performance on the racetrack, now custom-designed for your vehicle make and model. E-0646 K&N® air filters are tested on a SuperFlow flow bench to ensure increased airflow over a stock filter. View testing data for many K&N filters on individual product pages.


K&N’s state-of-the-art filter features thousands of microscopic cotton fibers, and an innovative design of layered, oiled cotton media helps to capture dirt and shield your engine from contaminants. Each E-0646 filter design is tested in an ISO 5011 laboratory to ensure excellent filtration efficiency for outstanding engine protection.
Over 100 million disposable air filters and their packaging waste end up in landfills each year. Choosing a washable, reusable product that lasts for the lifespan of your vehicle helps to reduce unnecessary waste.

Customer reviews and star ratings help our customers learn more about a product and decide whether it is worth buying. A complex algorithm is used to calculate the star rating, taking into consideration how long ago the review was made, whether the item was actually purchased in the AUTODOC online shop, and whether it was returned or not.
The tag "verified purchase" allows you to find reviews from customers who have actually purchased the item in question from the AUTODOC online shop. The "verified purchase" label applies to reviews of items purchased from the same account the reviews were submitted from. We still consider reviews without the "verified purchase" tag to be important, but we can't guarantee that the items described in such reviews were purchased in the AUTODOC online shop.
