Hi, does anyone have a picture of an 'unmolested' airbox?
Mine has large holes (45mm dia) on the top surface, directly above the intake rubbers, together with two 25mm holes on the edge of each filter side which have been blocked again. I presume I need to block the two on top to return to standard - or is it a recognised mod?
Cheers.

Holes in the top will simply bypass the filter elements.

Repair all the holes. The airbox will not restrict performance on a 350 engine much below full race spec.

Cheers Paul. As I thought.
