Hi all,

I have an 05 model WRX STi Type UK. Standard at present. What induction kit should I get to give me the biggest bhp gains. Can anyone quote reliable bhp figures for some common ones? I was thinking about the HKS Racing Suction Kit..

Looking to buy one tomorrow, so any good quick advice appreciated!

 

Don't bother, just go for a decent panel filter (green or STi)

 

Thanks for the advice, think I might stick with what I have!
