i no nothing about motors, and i just recently got a 91 crx with engine work already done to it. i know that most air intakes have fearly long about 2.5 inch tubes that run to the front of the engine bay. but mine has only about a 3 inch long tube running out of a timed fuel injuction box... is there an advantage or reason to why it would be set up like this? if needed i will try to put a picture on tomorrow showing what im talking about.

 

delete this post and post again tomorrow with the pictures.
