MWR Velocity Stacks - Kawasaki Ninja ZX-4R 2023 /+

To replace the original trumpets, MWR has produced Velocity Stacks in two parts, with an upper part (the trumpet) and a lower part, a ring to be screwed against the airbox for 100% sealing. A unique solution to protect the engine from impurities entering the airbox.

Each kit includes two double-cone trumpets, two rings and a “key” for tightening the rings to secure them and prevent them from coming loose again.

Our tip: make sure that when you remove the original chimneys, any kit or glue has been removed, so that you have a good seal with your new MWR Velocity chimneys.

No further modifications required
