Selling a new-in-box, never-installed Cold Air Intake kit for 1999-2006 BMW 323i, 325i, and 328i. My wife bought the kit as a gift not realizing it didn't fit my M3, but my loss can be your gain to the tune of about a 5hp bump and some sweet sweet inline-6 intake noise.

Hey guys, I am pretty new to CAI mods even though in some situations it is considered a pretty standard/beginner mod. Anyway my question is what would be a nice budget friendly cold air intake. I know it doesn't really show any exponential values of performance, but I do love the throatier sound...

Okay friends I recently found DIY's for both a heat shield and a cold air intake and I plan to do both. However, I have a question. I drive a 325 so my MAF is 2.5" diameter. Would reducing UP from the 2.5" MAF to 3" intake tube cause me much trouble? too much air flow? Wobbling? damage to the...

Searched around on the forum and couldn't find any info on this... I'm thinking about making my own custom CAI through bits and pieces I can buy at the local auto store and I can't decide on which air filter to go with. I want to stick with the non-oiled filters because of the horror stories of...
