Street High Performance Velocity Stacks Kawasaki Ninja ZX-4RR (2023-2025)

To replace the stock bells, MWR has created a two piece velocity stack, with a top piece (the trumpet) and a bottom piece, a washer to bolt everything to the air box for a 100% seal. Each set includes four bells, four washers, and a "key" to tighten the washers to secure them before they come loose.

We recommend using this set for street bikes, this set has two high and two low velocity stacks for a little more torque which provides a finer handling on the road.

Please note: When removing the original stacks, make sure to remove any caulk or adhesive so you have a good seal with your new MWR Velocity stacks.

Fits the following models:
