Hey I got this same Gruppe-M Replica in ebay for $440 shipped ($350 + $90 shipping)

I know this might still be expensive for others, but it was listed for $500 (+ $90 shipping). I shot him an offer for $350, but I wasn't really expecting him to accept it But the next day, lo and behold, I got an e-mail that I won the item

This was totally unexpected and caught me by surprise. I mean I already bought the flat K&N OEM filter replacement for the mean time (which hasn't even arrived yet). Now I have to sell it once I get it :mad:

I'm so psyched because for the longest time, I've been looking for a Gruppe-M Replica that I could afford, but $590 was still too expensive for me. I even asked Felix if he could help us to create one, but I guess I really couldn't wait anymore I even created, in anticipation, a lower bumper grille air ram intake (ala Dinan/Ksfrogman) before knowing when I could get a replica (I just have the hole covered )

I think the seller still have 2-3 listed... Now that the word is out, shoot him an offer for $299 No wait... wait until I get the intake and see if it's any good

Its been about year now with that intake and their great!!

I have A/T and that bring the rpm higher than stock intake.

Also sounds awesome!!!

As long as I have Original K&N filter, there is no huge difference between

real GrouppeM and replica!

All other parts has exactly same looking and dimension!!

anyone here can help me to post some video clip???
Hi zzinco79,

I just got the Gruppe M replica intake from eBay and it does come with an original K&N Filter.

I agree that visually, it almost looks the same as the original one, except for the CF shield. It seems the real one fits better on the side/edge that touches the underhood lines (the part of the CF shield you see when you open the hood). But I don't think it's really noticeable, specially if you haven't seen the original one.

As far as performance, I don't know any difference because I don't have the original to compare against. However comparing with the OEM intake, the car is definitely more responsive at the lower RPMs. The intake is also now audible, but not too much (it's just a nice growl that's not overwhelming/annoying).

I also tried to replicate the stalling issues I heard from other people who had their intake replaced. The only occassion I could make the car stall is when the RPM goes below 500. And the only occassion I could get below 500 RPM is when I'm cruising at speeds more than 55MPH and then shifting to neutral. So cruising in neutral at speeds more than 55MPH drops the RPM below 500 and stalls the car.

However, any speed lower than 55MPH and the RPM doesn't go below 500 (it stays around 700 to be specific - which is the same as idle I believe) and the car doesn't stall. I even tried rolling to a stop in neutral (many many times), but the car won't stall (because the RPM stays above 500).

I guess this is not really an issue for me because I'd never cruise in neutral while going more than 55MPH.

However, I'm just wondering, does anyone know what's possibly causing the RPM to go below 500?

I'm posting on here what I wrote to you in my PM.

The stalling issue occurred a couple of times early on, but hasn't in quite awhile. Either my car has adapted with timing/fuel adaptations, or I have changed the way I drive my car. I don't ever go from 55+ to neutral.

I'm not sure what caused this, but I suspect the increased free flow of air decreases the vacuum pressure more abruptly during quick changes from higher to lower engine rpms, but temporarily, which exerts control over the idle rpm.

Hey thanks for your reply/comments frogman

After you said that the increased free flow air might be exerting control over my idle rpm and stalling my car, I tried to reduce/shorten my lower air ram intake. After doing so, I no longer have any stalling issues The fastest I tried cruising in neutral (without the car stalling) is around 85MPH and the RPM stayed at 700

In the picture below, the white tube is what it used to be and the black tube is what it is now:

I guess before, my ghetto custom lower air ram intake was too close and it's producing too much airflow (which most likely is what causing my car to stall when cruising in neutral at speeds more than 55MPH).

In either case, this is really not an issue because I'd never cruise in neutral at those speeds So this Gruppe M replica is really great y'all Go get yourself one for less than half the price of the original one

Here's a photo of the top side of the replica intake:

Here's how it looks like in the front (I have a kerscher front bumper).

This is the bumper's lower right grille. You can see the lower air ram intake (the round hole in the middle-right side of picture) and the brake cooling air intake (left side of the picture that has some orange/yellow light):
