No Cut High Flow Velocity Stack
No Cut High Flow Velocity Stack

From our partners at 550 Performance, this velocity stack features a tuned length and diameter that increases power across the rev range. The stock intake funnel is absurdly long (to help quell noise) and chokes the engine above 7,000 rpm. Previously, the velocity stack from Honda's own CBR300R was a hot mod, but installing the part was a pain due to fitment and orientation. This part offers the performance benefits without the hassle.

Trust me if your interested in changing velocity stacks this is the one to get. No cutting the airbox and no alignment issues. Pop it in some warm water and wiggle it in. Seal with some RTV and good to ride.
The install took a hot pot of water a big screw driver and channel locks. It is a tight fit. Good thing it's made out of strong material. But once installed it's obvious it's better than stock.
