Is there a induction kit available for a non turbo?

 

yes there is, a k&n Gen2

eBay.com.my: K&N Gen 2 Induction Kit Subaru Impreza 57i-4000 (item 200277456966 end time Nov 14, 2009 00:44:28 MYT)

never liked it tho when fitted to my sport yrs back,too much at 5k but everyones different

 

Thanks for the link, what do you mean by too much at 5k?

 

it offers a deep intake growl,but when hard accelerating it sounds good upto 5k then it suddenly sounds like its missing an intake system,very loud and just seemed odd,nothing for 4000 rpm then this sudden huge growl

some like it,i didnt but you might,its a well made ssytem and fitted as it should no problems.
