This is no ordinary intake. Our Velocity stack Intake is completely custom molded. The radical performance increase is no accident. It was specifically engineered for the HKS Supercharger on your 1.8 engine. This air filter is the only elliptic curve velocity stack intake you can buy and is and perfectly matched and scientifically proven to feed the most air possible into your supercharger. We leveraged our years of experience at the highest levels of motorsport to engineer this game changing product.
Back to back testing on a stock class race boat yielded a 200 rpm gain over a competitor’s high performance air intake. 9100RPM->9300RPM. More radically modified engines could see even better results. Obviously, your results may vary. Non speed restricted tunes are recommended for best results.
Also recommended is the Uni Breather Filter when removing the stock air box.
