I was wondering if anyone with a 99 Civic could tell me what is the largest IC that would be able to fit in the stock bumper. I'm not trying to get the biggest just wanting to know what I have to work with. It's got the d16y8 engine in it.
TIA

 

You should be able to fit a 24x6x3 no problem. But any longer, you'll have to hack the bumper a little because of the piping.

 

Bump...anyone else??
