Perfect fit. Works as advertised.

I would give it 6 stars if it were an option. I have been using KN Filters in my vehicles for over 20 years. There isn't a better air filter in the world that competes with this one. It will increase your air intake and make your car run better. Easy to install and I swear it feels like I have increased my HP.

My expectations were very high given my previous experience with other K&N filters installed in my other vehicles. Excellent product that lives up to its promise of increased acceleration & overall improvement in power. Very fast delivery of item too. I received much sooner than expected in double box. Installed in a new 2015 Toyota 4Runner Trail making an excellent vehicle even better if that's even possible Hats off to the folks @ K&N
