Vehicle: 2000 911 Carrera 4: Based off some of the other high priced kits out there and its CA smog legal, I would say its worth the money. Install instructions were fairly straight forward but a bit confusing in some areas and I'm very good at this stuff. If you have any Q's, look on Youtube as there as a few videos that explain the install. The only issue I ran into was the plastic air tube intake (from K&N to the outside intake "wing") did not line up. Had to place an extra screw into the K&N plastic intake tube so it would align correctly. The sound is very nice and a noticeable difference over stock. Power increase..... well hard to say. There wasn't a "wow" moment when I tested/drove it so maybe a few extra horses (5-8 "ish"). Overall I'm satisfied and would recommend.

Changer mon filtre à air sur Porsche 996..

Excellent product, looks, sounds and performs better. Perfect fit for my car:)

Très beau bruit. La voiture "respire"incontestablement mieux.Assez long à monter sur une 996 tiptronic, prévoir 2h à deux. Quelques adaptations à faire pour que l'entrée du kit s'intègre parfaitement sur l'entrée d'air dans le capot. Prévoir de fixer l'entrée du kit sur un élément de carrosserie, sinon l'enesemble bouge trop.Attention car à chaque grosse révision, il faudra tout démonter....

Wow this air filter was amazing on my 911 !!!!
