I've had two sets of complete intake system laying around for a couple of years and never really paid attention. But now that I want to sell them, I see there are some major differences between the two UIM's.

My question is: Does one flow better than the other?

 

Care to post pics? The JDM UIM has the AWS solenoid and pipe deleted, but otherwise I wasn't aware of any difference amongst UIMs.

 

I will post as soon as I take pics

 

Do they look the same? Maybe you have a UIM from a different 13B? Most likely, as Rich said, one is JDM and one is USDM. Either way, pics tell all
