Performance Upgrades

I own a 2004 BMW 325Ci with sport package. I've added a Remus exhaust, aFe CAI, and will be upgrading plugs & ignition coils soon. Any other DIY performance upgrades out there that would be worth doing beside maybe a Shark chip?

To answer the question no. The only real way to get noticeable performance is F/I

Headers and a software tune, but nothing besides FI will make a huge difference in power. I say work on looks and handling.

Whats your budget buddy?

For butt dyno results get a lower geared diff, like mentioned and headers. There you have it, you just spent $350 and you can ACTUALLY feel the difference.

The E46 has no available modifications at all and nobody has ever done what you are trying to do before.
