Guest jwcanfield Posted September 30, 2002 Share Posted September 30, 2002 Background: I've got a N/A '83 280ZX which is currently almost all stock. Last week I replaced the catalytic converter (it was 75% clogged) and installed a new magnaflow muffler and got pretty good results (sounds and accelerates much better) I'd love to modify my car further but the emmissions laws here in Albuquerque, New Mexico are pretty draconian. I'm pretty much limited to low level mods until I get a pre '73 vehicle (read 240Z ). Because of that, I'm looking at changing out the throttle body and possibly adding a K&N Cold Air Intake. Finally the ?s: Are K&N Cold Air Intakes much noisier? Do they really make a difference on mostly stock cars? Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted September 30, 2002 Share Posted September 30, 2002 There is a noticeable good sounding low sucking noise that comes along with a clean K&N. It just sounds like a healthy engine sound. Its most noticeable when you punch it. It's not a noise that is anoying. You will notice better throttle response and a little bit of gain in horse power. Just keep cleaning it and oiling and it will last a very long time. Quote Link to comment Share on other sites More sharing options...
