Fitment is great and very simple to fit with instruction. Nice finish
Happy with product, hassle free and quick delivery
I highly recommend this product for the N52 engine 3.0 si. It's difficult to find quality aftermarket parts for the Z4. This is def one. It completely transformed the growl of my engine. I haven't dyno tested it but it def feels faster. My experience is coupled with an RPI Ram Air Scoop, and Super sprint X-pipe and power loop exhaust. It sounds amazing!
Great communication, and super fast delivery..
Very happy with product..
Excellent outlook
Great performance
Nice sound
It's the first time I use GruppeM's products, and the effect is great. I thought that the Ram Air system needs a higher speed gain to amplify, but I was wrong, just starting in first gear, already feeling fn2 very wild, same as I used to Using a poorly modified intake system in first gear, it is obviously compared with the sky, an incredible product that really gains any RPM
Fit, finish and install are all excellent. Comes with everything you need and with clear instructions. Looks amazing, intake growl is superb. Throttle response and power felt much improved. Makes driving the car more engaging!
I am super satisfied with both the quality of the intake, and it's sound ! Looks very nice on the engine bay. I already had a conical cold air intake with a boot connected to the front bumber's hole, so the reactivity of the gas pedal was already impoved compared to the stock intake, but it has been improved even better with the GruppeM. On high RPMs you can hear the engine screaming through the intake, with the carbon fiber airbox making it resonate even louder in a beautifull way. It is, with no doubt, the best ram air intake you can get for your E46.
Ordered on November 24, delivered home on December 19. Shipment took only 4 days from Japan to France.
Also a big thank to the client support that I contacted on Instagram, very reactive and a pleasant person to deal with !
It’s a really nice looking intake and sounds great on my cl9, brings a smile everytime I drive the daily
