Got all the parts as recommended Aircleaner/filter, silicone tube but most important so it would all happen the air filter adaptor. Now it was one of them basic adaptors you grab from supercheap/autobarn a TFI racing product.
The model is a 9007 which is for the mx5 (non specific NA,NB...), even says on the packet. Bolts on no worries but leaves a gap on both the top & bottom larger than the grand canyon (ok maybe not thaaaat big). Now I've left the cork gasket on of course. But shouldn't this area be fully enclosed, I mean otherwise whats the point of the filter.
Now am I missing something here or is this just an example of a crap aftermarket product?
I'll pop a pick up when I can to show what I mean (can't find my cable from cam to pc

Anyone got any ideas/suggestions?
....and no manga_blue I'm not going to run off and buy an SP,SE or change my plug leads
