1997 Z3 Cold Air Intake?

Hi,
I have a 97 Z3 2.8l six cyl, 5 speed manual roadster that runs great!
Is it worth putting a cold air intake into it and if so, which do you suggest?

The Z already has a "Cold Air" intake. the air is brought in to the engine via a hose that collects air near the front grill. That is channeled into the Air Box that is then piped into the intake. The bulk of the after market kits sold and installed are not "Cold Air" intakes and are just less constrictive pipes with more open filters. Often they do breathe better but most often are pulling in hot engine air.
you might first look to see if you can improve your air box. The 4 cylinder car owners often do the "fogg" modification. do a search and find the how to on that. There are some good kits that do actually collect cold air but they are not cheap kits available at the auto store.

I have a Conforti, but mostly for looks and sound. It doesn't really add much performance for your money. If you want to stay NA and tend to rev the engine to higher ranges (over 5K rpm), you get better returns by doing an M50 manifold swap

There are not a lot of gains and 1996 and later cars if you stick with external mods. You really need to change the cams to get any serious power gains.

I'd recommend for you to check out the aFe P Stage-1 intake. The Stage 1 cold air intake system produces 4 max horsepower, 5lbs. x ft. torque. Includes a durable 16 gauge, powder-coated heat shield; this air intake system features a washable/reusable conical air filter. It'll give the car a little extra kick and will definitely sound nice!

fogg box FTW! A friend of mine helped me install one on my '97 Z3 many years ago; and it worked like a charm. It's probably the best bang for the buck in terms of upgrades for your Z...
