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 !
