I have a 99 civic si that will soon have a inline pro manifold and precision sc34 turbo, i am wondering if a filter will fit?
can you post up pics of your intake setup?

 

You might have clearance issues with a stock radiator fan. I suggest running a slim fan there.

 

u can run a cai and put a filter on the end, kinda like a drag 3 kit.

 

should that clear with the stock fan?

 

bad comes to worse - you can get a filter for next to nothing and zilch restriction in flow by using a stocking doubled or trippled over it self then held on with a 'worm-gear' (can't recall the other name for em). Less aluminum (highest thermal-transfer properties of conventional metals) piping to heat soak as well. Since they're nylon based - they don't melt or catch fire from anything but a direct flame - and if you've got open flames near your turbo...you've got bigger problems than "what air filter to use". **** not even a commercial air-filter woudl survive that.

Yeah - you won't get the stunna points, but if it's good enough for open-element dragsters - it's definitely good enough for you.
