BULLDOG Posted November 10, 2014 Share Posted November 10, 2014 HI, Can anyone give any advise on an induction kit for a 2.5 Sti. Are they any good? What is the best one? Do they increase performance? Where do I find one? Quote Link to comment Share on other sites More sharing options...
stants Posted November 10, 2014 Share Posted November 10, 2014 Personal preference really, have you looked into just changing the paper filter for a more free flowing one like a cosworth or similar? Check out scooby world or scoobyparts.co.uk for various options Quote Link to comment Share on other sites More sharing options...
Jay762 Posted November 11, 2014 Share Posted November 11, 2014 echo Stants statement - it appears to be a personal thing - looking at a 330 type option for yourself could be good - hi flow panel filter eg Cosworth just as long as its oil free that is fine, fuel pump RCM's are getting better feedback currently than Walbro, intake pipe samco, zero sports prodrive etc, rear silencer and remap here is an example of prodrive option http://www.subarupartsstore.co.uk/product/Impreza_WRX_STI_2.5_2008_-_onwards_Performance_Pack_SACC2811 1 Quote Link to comment Share on other sites More sharing options...
ChrisD Posted December 19, 2014 Share Posted December 19, 2014 Agree with the above, but from what i have heard, People seem to get better results with say a K&N flat panel filter with higher air flow, over the expensive K&N Induction Cone Filter ? Pretty cheap upgrade for one of these and easy to fit! Quote Link to comment Share on other sites More sharing options...
stants Posted December 19, 2014 Share Posted December 19, 2014 Not as much heat soak and if you leave it dry no oil to mess with the maff [emoji16] Quote Link to comment Share on other sites More sharing options...
