I was just installing my spearco intercooler when i notest one side is smaller in diamiter than the other and im not sure witch of the big and small end is in and out? Im sure there is a reason for this so i just didnt want to throw it on..

 

im guessing the side going to the throttle boddie will be the larger side and the smaller side will go towards the turbo.

 

ok. thanks, ill try it that way...
