Excellent product that fit. This will save me money many times over, with better fuel economy and not having to change the original filter on a regular basis.

A new K&N air filter and oil filter is ALWAYS the first thing I do with a new vehicle. I replaced the air filter in our new to us 2014 Cadillac SRX and have already noticed a 1.5 mpg increase to our average mileage. Ordering process was extremely easy - enter the year, make and model, pick a product, add to cart and you're done. Delivery was also quick to the west coast.
