How can one tell by looking if an intercooler is a 12v or 24v model?

 

Anyone know? There has got to be a way to tell the difference by looking at them. I have heard that the 24 version flows better. How about it Gurus.

 

Well, mine is a 12V and it has these numbers on it: 52027562 then below that one,: 83403D and then 2497. One of these must be the P/N. I expect it to be the 52.... Hope this helps a little.<br>Ed<br>

 

Thanks for the numbers. I will have to look to see if mine has the same or similar. I was hoping that there would be a physical difference that would jump out to the eye. Like the number of passes or height or depth measurements.

 

Can anyone substantiate the claim that the 24v version flows better than the 12v version. I have heard that there is some EGT reduction to be had if a 12v'er were to change the intercooler for a 24v version.

 

Update:
According to my local dealer the part numbers are as follows

52027562 94-98 12v
52028482 98 (only) 12v and 24v
52028724AF replacement for 94-02 this part number has changed several times over the last few years. The last character has changed from an A to B to C etc. until we have an F.


So we have cleared up the lineage of the inter-cooler. Does anyone have any experience with changing and earlier 12v cooler to a 24v cooler and noticed reduced EGTs or an increase in performance due to a rumored better flow characteristc in the later coolers.
