I know TCD has an intake for the E28 M30B34, but not for mine. As far as I know, no company manufactures a bolt-in cold air intake for these engines.

I was wondering, if my information is false and a company does produce this, or if perhaps some of you 535i guys have rigged up a nice DIY setup. Keep in mind I'd rather keep the stock then have a system that looks like it came out of the garden.

Thanks in advance!

When you say "intake", what are you talking about? Are you asking for an *intake manifold?* If so, Dinan makes one, but it might cost more than your car is worth:

If you're talking about improving air flow, maybe there's a reason why nobody has made a "bolt-in cold air intake." IT DOESN'T MAKE A DIFFERENCE!!!

Do you think some after-market company, even one with resources like Dinan haven't considered it? One thing to consider, BMW spends millions tuning their cars.

The key here is COLD air flow. The stock system does this very well. IF you really think you need something "extra," put in a K&N filter. You'll spend $50 and feel better....
