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.

  1. Jim

    I’ve been into performance parts for decades. In my opinion this the absolutely the best air filter I’ve ever seen.

    On my Riva stage 3 Yamaha FXSVHO I gained 110 rpm and almost 1 mph with this filter over the one in the stage 3 kit.

    I’m sure it would be much more over the stock intake

    Easy install and opens up the engine compartment. I can highly recommend it

    With this intake on a 2016 FX SVHO with a free flow exhaust it made such a difference it put me up to the Revlimiter before I put this air filter on I never hit the rev limiter now I bounce off of it amazing

    Best setup ever!! Was topping out at 68mph on a 2014 svho.. Now 72.74mph with macsboost filter duck redirect and ribbon delete. The slurping sound of the supercharger alone is worth the $140. You guy’s killed it. You squeeze the throttle and hear the suction that ball breaking power of the 1.8 svho with no air resistance. Great job!!!
