Cold air intake??

Should I look into installing a cold air intake to my x3???? Seriously considering it since I have a 2.5 with 184hp or so just looking to get close to 200...what do you guys think?

Adding a cold air can add a few horses to the M54 engine but if your looking for more power a cold air intake combined with a DME performance flash tune is the best way to get the 184hp closer to 200hp. I have a cold air intake and a flash tune on my e83 and Im quite satisfied by the performance increase.

Interesting suggestion.... Is there a flash tune for the 2lt engine? How much does the cold air intake cost?

Look up Shark Injector. Its a device you plug into the J1962 port (OBDII diagnostics port) and it remaps the fuel injection system and timing along with tightening up the throttle response. Its a nice investment take a look at it.

please keep in mind just about any performance enhancement can only be done to the pre-2007 gen models. Believe me for for almost 4 years I have tried to find anything that was under $3k that would give more than 10bhp. Really not out there sad to say.

Really the only reason I will be looking to upgrade in 9 months or so. My wife's MCS is like a lego. There are so many toys that can be bolted on. She won't let me near it, Lol.

This started years ago when my Dad thinking he was being slick sold me the family station wagon. It had a 350 small block. He realized the error of his ways when he borrowed it one day and left rubber on the asphalt just trying to back out of the driveway.

So no it's not just BMW's I have to change. It's anything. Tim from "Tool Time".

Honestly, if you want to put an intake on, you should just take off the air box an put a filter on the stock intake manifold hose. Get a filter with a clamp on it and it works just the same as a 200 dollar intake but costs 25 bucks. You can here a difference in the motor in between 3 and 4 thousand rpms. I would like to get this comp tune though

First post!!

+1

BMW engineering surely does flow analysis on these and "tunes" them.

Case in point. I have a 98 Maxima. Naturally I am on the maxima.org forums. You can go over there and find lots of evidence of people who have installed cold air intakes and then go back to the factory intake. In this case, a little top end hp was increased, but and a net loss through the rest of the RPM range.

That and it just sounds obnoxious.

I installed a cold air intake, chip and exhaust on my old Z3. Sounded great and made a lot more hp.

Make sure the intake draws cold air. Just putting a filter on in the engine bay will not help much. Cold air is denser and will give a much better boost.

It will work, just not optimal. A cold air charge is much better than hot for power.
