Drilling the airbox!
I'm having a discussion on another forum and am being told that drilling the airbox won't improve things.
I know Performance Ford did testing on this a while back and did find improvements but I need a techy answer as this guys being a bit of a plum

I had a K&N cone filter on my series 2.Just changed it for this.

Looks alot neater in the engine bay aswell.
Iv,e just had it set up at JAMSPORT where the test for all these induction kits in the mag took place and they recomended the driled airbox.

I drilled the airbox in the micra yesterday and hasnt really made any difference to performance apart from change the noise when the butterfly is open about more than half way. Just going to run a front air feed to it and leave it as it is.
At least it has gotten rid of that stupid whining noise that engine makes at high rpms

ok .. get the airbox .. take the top cover off..
totally remove the front part of the top cover ( bit with the hole in it).. job sorted not drilling required ......
had mine like that and it worked perfectly running at 22psi on the track
much neater and stops loads of hot air entering the air filter
had an act guage in the air flow from the metering head and the temps were alot lower with the box than the cone
