2 piece – double cone- MWR High Performance Velocity Stacks for Kawasaki Ninja 250/400 & Z250/400

To replace the original gummy trumpets we have to make a two piece velocity stacks , with a upper part ( the trumpet) and a lower part , a ring to screw all together against the airbox for 100% sealing. In our opinion to only solution to protect the engine for dirt coming into the airbox

Each set includes two double cone trumpets , two rings and a “key” to tighten the rings to secure for coming loose again.

Our advise : make sure when you have taken out the original stacks all kit or glue will be removed so you will have a proper sealing with your new MWR Velocity stacks

No further modifications needed

These Velocity Stacks needs some real tune adjustment for max. performance

For maximum performance you can use the filters MC-040-20HE or MC-040-20R in combination with these Velocity Stacks
