how big were the holes? i drilled about 40 10mm holes and removed the clip on bit on the wing side.

i found my induction kit was only quicker in the cold, whereas airbox was better all year round. i have now however put my induction kit bk on but its alot closer too the turbo so its better than anything was before as it bypasses over a meter of heating up pipe work.

drilled about 6 holes in the bottom and another 6 on the side and it picked up a bit quicker the induction kit had the same effect but now i got a grizzly bear under the lid as well.

it does a bit but tbh that only cars that have bigger engines that produce lots of heat
indution kit is eaiser to do take bout 20mins to do drilling airbox to many and u lose pressure and it fooks it up plus uve gotta sand each hole to make sure no bits of plastic end up where they shouldnt

could you explain to me why? wy does it work better?

panel and drilled airbox.

Which one??

Drilled air box with sports filter or induction kit??
