Product Review:
The Gruppe-M cold air intake looks fantastic, but doesn't really seal in the engine bay. The "seal" is made by screwing the molded air filter housing against the body of the car. A rubber seam in the filter housing mates with the body molding to make the seal. It doesn't seal nearly as nice as the factory unit, but makes up for it in the looks department. The Gruppe-M CAI it is fitted with a nice K&N air filter,
which probably flows much better than the stock unit. In my opinion,
it's the K&N air filter that accounts for any performance gains -- not the
unit design itself.
