I thought I may as well post here as it's semi related. I ended up going with this air box from R-factory, Aluminium backing plate, fibreglass outer with a knife edged 'egg ring' with steel mesh screen fitted. It's bewdiful Most important is it will let me run big stacks.
Will the mesh effect air flow into the box, it's similar to flywire only it's stainless steel?
This one is for Alan Fields, what brand airfilter do you use in the 280 airbox? My plan at this stage is to duct it in a similar style to your green 260Z.
Thanks, Gareth.
