I have stated earlier that I would write a full review (with pics and sound clips) of the GruppeM Ram Charger....

This is for the GruppeM Ram Charger (Carbon Fiber) for a STOCK E46 323Ci:

I purchased the GruppeM from Renn-Sport. Great service and very speedy! (thanks sam!) though it was the longest wait ever, UPS ground, 7 days! I got the Carbon Fiber instead of the Carbon Kevlar for two reasons: 1) the kevlar would have taken an additional 4-6 weeks for delivery and 2) the kevlar has yellow and green in it; though the weaves look outstanding, the green and yellow doesn't fit my engine's motif.

Mr. UPS came at the end of the day! Opened the box and my first reaction was "wow, sooo soo beautiful" The carbon fiber sparkles under the light. Soon the wrapping was opened and once you feel it, you will notice its build quality: perfection.

Scrambling upstairs to my room where my computer is, i pull up the installation instructions from renn-sport. Install instructions Quite simply the easiest thing ive done for a long time. In a matter of minutes, the assembly was done, ready to go on the car.

My friend/roomate wanted to help install the baby. So we went out and opened the hood. Again following renn-sport's instructions: two 10mm bolts off, unclip the MAF, disconnect the kidney air conduit and voila, the OEM airbox was out.

One problem I had was the location and removal of the headlight vent. Since the instructions were for the 330, I presumed the vent did not come in the 323 since I could not find it. So I continued on.

Popped the GruppeM in, connect the MAF, tightened a few screws, done! The mounting bracket was not used here since 1) the instructions says it was not needed and 2) once you install it, you can see its very secured without the bracket.

There was a short period after the install, where we just admired the engine bay. Ok on to the engine start!! YAY

Started the car; very normal. No difference. Friend told me to rev, so I did. Our faces smiled. The sound is amazing! Theres no words to describe it. ROAR with a hint of HISSING (from the intake sucking so much air). The intake has changed my car's image, to an average sounding car to a roaring beast. You just cant get enough of the sound (atleast I cant get enough of it).

The sound is generally normal under 3000RPMs, at this range, all you hear is a very very faint hissing sound. Almost non-existant. Pass 3000RPMs, the thing screams.

Performance wise: you can actually feel the difference, it may be different for other models, say the 330, but in the 323, you can really feel the difference. I believe it's the throttle response time; the response time has shortened.

I've heard the design on the intake is second to none. The specially designed shape of the intake forces air into the chamber where air is focused to one point which enters the engine. The kidney air inlet channel (which used to be the source of the air for the stock airbox) is now a cooler for the heat shield; the opening of the kidney air conduit is directly next to the GruppeM intake. Excellent design IMO

Retail for the GruppeM intake is somewhere around $700. Renn-Sport had a special for these little babies.

I would definatly recommend this to anyone who wants the best of the best. I must say for an intake, it is pricey, but to me, just the phenomenal sound this thing produces is worth every penny, not forgetting the :pimpin: look and on par if not superior performance.

Photos and sound clip comparisons will be up tomorrow!

Just put mine in as well.

My 330 felt a bit sluggish and the GruppeM definitely cleared that up right away.

No problems with install, went in about 20 minutes. Drove out and put in a fresh tank of 93 octane and...happy trails.

btw, Renn-Sport is the best.

i dont get why someone would pay more than double the price for a gruppe m when a benfer 1 piece cai has about the same gains and sound. is it just mostly looks? or does the gruppe m sound better or yield more gains?

i had the benfer 3 piece before switching to gruppe m...and i gotta tell u ... the gruppe m does sound a lot better, esp with our golf-cart sounding 323s. I mean it just screams after 3k. It even sounds better along with an after market exhaust!!!
even though it's hella expensive, it's worth the fun though.
as far as power gains, i think it's all in our heads...
