are the s4 and s5 top mount intercoolers the same??

 

nope, the s5 is a bit better.

 

Serious? are they interchangable?

 

hmmmm...i also would like to know if there interchangeable..

 

i had a s5 tm on my last s4.

 

How exactly is the S5 TMI any better?

 

Biger = betor. I thought they were the same.

 

i thought they were the same too.... never seen any info about it here OR elsewhere

 

The S5 IC has slightly bigger tubes and a slightly bigger inlet connection. It flows ~5% better than the S4 IC based on pressure drop measurements. It is not directly interchangable with the S4 one because the S5 UIM (which supports the TMIC) is higher that the S4's, so the mounting brackets are different.

 

The Kouki S5 IC has a 2.0" (or 50mm for our metric bretheren ) inlet.
The Zenki S4 IC has a 1.75" inlet.
That makes it NOT swappable, unless you change out the hose...
