gruppeM style vs. heatshield style CAI - United Bimmer Community

**Spieluhr** · 06-10-2006, 12:44 PM

alright, I need a little more umph to go with my ride and am looking to go with a CAI and software cause they are necessities that I have put off for far too long.

Now for the cai, Umnitza offers...

GruppeM style, carbon fiber air box cai, for $229.00

AND.

a standard CAI, with regular heat shield, for $249.00
http://www.umnitza.com/product_info....roducts_id=113

now, in your opinion, which has better performance? and do they both fit with ZKW's?

OR, should I spend less money and do the m50 intake manifold...
choices choices choices...

I would like to know these things aswell.

the gruppe M intake doesnt look like it will fit that we// w/ zkw's. i could be totally wrong too :P. i have the conforti intake and its kind of a tight fit w/ the zkws but it works really well. i would recomend the conforti, or the other standard cai. did u ask umnitza about the two and which they recomend?

I say just get the second one. The first one looks great though.

The CAI has no known increase in HP or torque. I will be honest and that I have an intake, but I don't think it made a difference in performance. Dyno your car before and after the intake to see if it makes a difference.

The chip would do more for you, by increasing RPM, removing the limiter and changing the air/fuel ratio. As for the intake manifold, I have heard various rumors that it can help or it may not. I know for my car, to replace the intake manifold with one that increases the airflow is so labor intensive that the HP and torque gains are not worth doing it. I guess to each his own.

it's a fairly easy DIY with the m50 intake mani. on the m52.

and only about 350-400.

I think you should get the cosmos intake, but get the new version 2 instead of the original, which I have.

I think that for an intake paying an extra $100 for those 2 isn't worth it. Of course this is IMHO.

you'll get more out of the manifold if you have an intake though, my opinion would be to go intake, manifold, software

If you are thinking about airflow, intake, manifold, headers, cats, exhaust and then a chip. Ideally everything allows more air into the engine and out.

I'd get the Gruppe M
