We have been manufacturing our V2 version of our CSL airbox since 2017. This version is a huge improvement over it’s predecessor, incorporating CNC machined flanges where the snorkel bolts to the centre section, carbon fibre intake trumpets and turned aluminium ports for the breather hoses. There is really no comparison.
