Cold Air intake - United Bimmer Community

**justinostman** · 08-10-2009, 10:07 AM

Hey everyone,
I just got my first bimmer-1992 325i 2.5.
I am wondering if anyone has any input on installing a cold air intake kit. Is it worth the money for the gains?
thanks

I'm sure some folks will disagree but NO it's not worth it. These cars came with cold air intakes with calibrated MAF's from the factory. Changing that can and often does screw up the air/fuel mix, and more often than not reduces power and efficiency. Depending on the style can lead to hydrolocking in heavy rain/puddles (BAD juju). It can also change the way air flows into the engine (not in a good way either) and that's what screws up the MAF reads and AF mix. One other thing if its the style that picks up air right below the bumper, that's NOT cold air. Right behind the headlight or replacing the headlight is the best......but that's where it ALREADY gets its cold air from AND its factory tuned to do it the most efficiently. Unless you're going super huge mod, big turbo/supercharger, head, valves, custom computer, exhaust as a whole package by someone who actually does that for a living. Keep your money in your pocket.
