Very happy with my air filter and cabin air filter. As always, with every vehicle I own, K&N filters do the job.

Put this in my wifes truck; immediate difference. Truck ran great, more responsive, and I'm happy knowing that I'll only need one (just clean it when it gets dirty). Well worth the money.

I have used K&N high flow air filters in every vehicle I have owned in the last 25 years at least. The fit is always perfect and the result always the same.. improved performance and fuel economy. I very much like the ability to clean and reuse the filter for the entire life of the vehicle.. a one time expense approximately equal to the cost of 2 or 3 regular filters, saves a pile of money over time.. especially if you maintain and keep your vehicles for 10 years or more... worth every penny.
