Are they worth the big $ read that they pull in more air but really what benefits do they give.
one I like is open top
Replacing you stock air filter with a high flow aftermarket filter is a good idea if you want better mileage and performance. But k&n isnt the best out there. They use oil to catch the dust, and if over oiled(sometimes they come this way) the excess oil can mess up your mass air flow sensor and line the throttle body with oil. They do make dry high flow filters that are far better to use…brute force is one brand I can think of right off hand.
