I use 7B's. Have always got them off ebay actually (best price) and they've been fine.

im in nottingham mate

Yeah. I won a set of brand new boxed 7B's on eBay, delivered, for £23! Mars bar in the fridge (cool) :thumb:

nice one got yourself a bargin there

well after putting some new spark plugs 7bs in & still no joy today i took all the air box out again cleaned everything out & noticed on the resonater chamber the bottom pipe which attaches to the bottom of the boost solenoid didnt seem to be on propperly, should there be a fixed mold on the resonater chamber as mine has like a brass tube which you can take out which the hose slots over? i fixed it best i could & took it out for a drive at high boost 5kit doesnt seem to be hesitating as bad or popping anymore could this be down to that pipe not being fixed propperly or is this pure luck it seems ok now?
