While that certainly would help, on my new 1997 Cougar Sport (V8), I installed a new, out of the box, stright from K&N replacement filter. It contaminated/damaged air intake sensors- twice in 60 days...documented by Ford engineers & Dealer...they put it in writing on the OASIS report. I pulled the filter in front of the tech & service writer with the install of the 3rd intake sensor....still own the car, not a single failure. K&N would not honor their warranty either stating "They must be wrong".
