I recently installed a K&N drop in air filter on my 93 explorer and its still not as powerful as i'd like Dead Link Removed so i was interested in getting a new induction system, like the KKM that was reviewed in this website. This may be a dumb question, but i was wondering if having both of these devices installed at the same time is bad. Also, on a lighter note, the same car celebrated its 75,000th mile today, without any major problems!
