Here's a free mod for the 93-97 Intrepid / LHS crowd with the 3.5 liter V-6. Take the intake hose off of the air cleaner box (the one between the box and intake plenum) and pull the air silencer horn out of the hose. It's about mid way up the hose and can be a bitch to get out, but it's worth it. this horn is supposed to keep things quiet in the passenger cabin, but the increased noise level is minimal. You will notice the hole in the horn is about half the size of the hose. I did this mod myself on the 96 Intrepid I used to own and could tell a difference in both performance and highway fuel economy (provided you can keep your foot off the floorboard! lol). You will definately notice it when you kick it in passing gear! I never did the K&N filter swap, but it would seem that would help out even more. Hope this helps!
