Amazing filter. Installed into vehicle and noticed increase in performance immediately. I have been purchasing K&N filters for over 20 years installing in all my vehicles. Will continue to do so and recommend to others. Great product.

Best and only air filter for all my autos and motorcycles. Gives my vehicles more air, power and stressless engine running. I will keep replacing OEM paper filters with K&N always. Thank you.

After installing the new K&N filter. I immediately noticed a difference in acceleration. We had a long road trip planned and the mpg increased on my vehicle. Highly recommend this filter.
