MTech supply Green cotton-gauze filters with their conversion kits, but they're just rubber neck universal filters so really are at the worst end of all induction kits.
You'd be better off buying some nasty Max Power filter off ebay - basically anything with a nice fully-radiused inlet on the base to get airflow smoothly into your inlet manifold.

The rubber necks will be full of right-angles.

Wank.

The restriction of the original airbox is in the top pipe:lol:
that's the reason you should fit a cone filter inside the original airbox and then run some additional 80mm pipe to the airbox!
or buy a cheap sealed unit for 35£ from E-Bay, because it improve the power slightly over 5500 rpm till 7200 rpm:)
I have an AP22 from race technology so I can prove what I'm saying:)

^^^exactly what happened to me with piperx filter i got off mate so swapped for a K&N and i have no probs (1.6tho)

Im running a Green filter on my valver and all seems good... Its a pretty cheap cotton gause one but seems fine. TBH I cant see the point in spending £70+ on these 'amazing' 5bhp + filters. I stuck a Pipercross on my 1.2 16V engine and it did nowt but cause flat spots and make a noise.
