Hayabusa gen1 airbox which was made by Cosmick for my Westfield Megabusa, (they don't make these) this helped me lower my engine dB for
trackdays.
the airbox has been trimmed down and resealed to fit under a Westfield V8 bonnet, but sure this will fit under other bonnet. A much better alternative
to the sausage filter.
Comes with a K&N filter inside.
Will post at your cost.
Offers?
I thought I recognised that airbox. Well worth buying if you are concerned about noise levels at Track days. This will reduce the intake noise substantially.
