A friend of mine (he's a member on here but can't get on the forum at work) has recently bought all the gubbins to hopefully take him up to around 300-ish hp and has only 1 thing (so he tells me heh) left to get, an air filter to go on the end of the of his SIP.
I said that its more likely that he'll be recommended an apexi one by fellow fccuk'ers, but he wanted to know his other options.
I myself run a BMC, but then my car isn't much more than standard tune

So, any advice?
Thanks in advance

Dan
