Pete in PA Posted July 31, 2005 Share Posted July 31, 2005 Has anybody seen the display at Advance Auto? It's for cars, but shows how much more air the K@N flows then a Fram fliter. Convinced me. Flows the same as with no filter in place. I'm just wondering what happens with my 99 Monte Carlo if I get one. Will the FI inject more gas in closed loop mode, and can it compensate enough? Will this give more power AND mileage or not? Or will It just set my check engine light and put a code in my computer? Quote Link to comment Share on other sites More sharing options...
blackhawkxx Posted July 31, 2005 Share Posted July 31, 2005 Or will It just set my check engine light and put a code in my computer? I have one in my truck as do many many people with no lights or codes or trouble. Quote Link to comment Share on other sites More sharing options...
Mikey Posted July 31, 2005 Share Posted July 31, 2005 My question is how much does it filter? Quote Link to comment Share on other sites More sharing options...
Pete in PA Posted July 31, 2005 Author Share Posted July 31, 2005 Notice any improvement? Power, fuel economy? Quote Link to comment Share on other sites More sharing options...
Furbird Posted August 1, 2005 Share Posted August 1, 2005 K&N's definitely worked. I had one in my old copcar and it picked up a tenth at the dragstrip just with a filter change. I've had one in my Firebird Formula since I bought it from the previous owner, and have since had to clean it. I bought a paper filter so I could clean the K&N and still drive the car. The one day I had that paper filter in was the only day I had that paper filter in. It makes a big difference on my car, but my car makes 450 HP on the gas so it sucks a LOT of air in. The more HP you have, the more difference it makes in drivability. Can't help you on the gas mileage question. Formulas are not anywhere in the neighborhood of "pocketbook friendly" in the fuel mileage department! Quote Link to comment Share on other sites More sharing options...
Pete in PA Posted August 1, 2005 Author Share Posted August 1, 2005 What year Formula Firebird? Just want to know OBD I or OBD II. Quote Link to comment Share on other sites More sharing options...
Furbird Posted August 1, 2005 Share Posted August 1, 2005 1996, OBDII, but it really doesn't matter anymore cause it's missing a couple of items commonly known as a household pet, or in my case, target practice for the .40 and retrieval training for my pitbull Quote Link to comment Share on other sites More sharing options...
