It fit really well in my engine bay. It’s more rigid than my last filter and seems like good quality. Fit on a Gt3076R turbo. Flowed 390whp.

I used it for my supercharger intake house, low profile which helps on the fitting, you can clean it and re oil it again using the K&N filter charger cleaning kit. Non restrictive airflow means more horsepower. I have a V8 383 Supercharged Stroker Engine and works as intended.

I've had this installed for about 5 years now on a 2 rotor RX7 FD with a GT35R. Dynoed around 475 with the filter on but didn't check without, so it can definitely make a little steam. I may replace with a larger one as after this much time I feel like the filter is getting clogged to the point where cleaning it with the recommended kit isn't helping anymore. Great little filter though!

Perfect item for many applications, I used as a cheap alternative for a golf mk4 which had previously had the air box removed.
