I use K & N air filters in all my cars because I dont want to spend the money to buy and have a cold air system installed for hundreds of dollars and take the chance of getting a ticket for modified other than factory to my car by the police,my car runs better than new from the showroom with the K & N and I can simply take out the crappy paper filter and just replace it with the K & N and no more wasting money on the air restricting crappy paper filters every other oil change! I simply use thw K &N cleaning kit and put thw permanent K & N back in the car.I definitely recommend getting a K & N reusable permanent air filter for your car and then you will really enjoy your car much better! Also rest assured that it is 100% legal and no need to worry about getting a fix it ticket from a smart ass cop that feels like taking out his frustration on you! Yes it is worth every penny, and probably will cost you around the same as if you went out to eat dinner at your favorite spot.I am not getting paid for thi review, I am a happy satisfied customer with the K & N filter.
