Cosworth's High Flow Intake Systems feature increased surface area of the element, large smooth radius bent aluminum inlet tubes for superior air flow management coupled with a high flow air filter for maximum air flow and performance.

Each kit includes an integrated heat shield designed to isolate the air intake from engine heat - delivering cold air into the engine for superior power conversion. The filter element is large, conical in shape and engineered to dramatically reduce intake restriction resulting in additional power and torque.

Costly, but worth it

Easy install, took just under an hour. Instructions are proper. Amazing noise, installed with Perrin turbo inlet tube, mates up nicely. Everything about this product feels solid. And as a side note, for those of you worried about water intake, the Injen 1034 Hydro-Shield fits perfectly over Cosworth's supplied filter.

Ive had this in my car for about five months now, and im still loving it. love the sound, the extra power; not a ton, but definitely noticeable. supper easy to install, but if your from CA and time for a smog just remember to keep your stock CAI because this item wont pass smog. highly recommend anyone whos shopping for a CAI to pick up a cosworth.

This is a well built product and went on perfect. In the factory picture it shows the filter going inside the fender.. I would say 1/2 of the filter is in the fender if that and is visable from the engine bay.. vs the aem completely in the fender. It is a good mix of the SF and cold air..

I received the CAI and install took less than an hour, the hardest part was trying to slide the silicone boot over the turbo inlet, it's a tight fit and when the air box is tightened down it doesn't line up flush with the inlet tube. Had to loosen the air box to get wiggle room and some elbow grease to slide it on enough. Should also add on the 11-13 wrx there is only one bolt on the frame for the bracket to secure to but I haven't had any issues yet with it wiggling around. This product sounds amazing, looks awesome and I can feel a little more responsiveness from the throttle. I kinda regret spending over $250 on a bov when I should have gotten this. Overall I'm very satisfied with this product

    I just bought this intake for my 2014 wrx and it has a great sound to it but it feels like i lost power in the mid range between 3-5rpm. i swear it feels like my car is slower now. i installed it and re installed it to check and make sure i had no loose fittings. Any ideas what is wrong?

    • A: A proper tune would be recommended, although tuning is not required for intakes there is always more benefits to having a vehicle tuned for it.
