I’ve had 2 other intakes besides this Perrin one, MAP and Cobb redline carbon fiber. Map was a 90 degree so not good for airflow but it did rout into the fender. It was also super loud. But! The carbon fiber intake was too quiet but was too big for my new setup. The Perrin does a slight curve good for airflow has the air velocity inside the tube it’s all metal great design and super loud when in boost. Great design for my stock turbo setup. I make around 350 wheel with this. Also it comes with the oiled microphone looking intake filter not the paper one pictured but I think oiled is better. Great job subimods great job Perrin.
