If you can see straight through it.
I would label it a hi flow core.
It should cool better then you had if the old was a hi flow core as well.
This one is much larger then your old one.
Looking for your results.

 

Mishimoto makes really nice products and you can't beat their warranty

 

What was the temp outside when you saw 125-141 IAT?

 

80 maybe. Normal southern California day.

 

You can definitely see Straight through the ebay one.
(Pay no mind to the blue bottle in the background.

 

That's the worst (but highest flowing, lol) eBay cooler I've ever seen!!

 

It was tight but I got it in there. I'll post some screen shots of the IAT differences tomorrow.

 

Wow no kidding, its more like a air straightner than intercooler lol
Probably would of been almost better off without it..

Should see a good difference out of this good choice.

 

This is the old ebay cooler. After crusing on the highway for a bit and the doing 4th gear pull.



New mishimoto cooler. This was the second pull, i did back to back pulls to try and heat soak it. First pull was 110. Both coolers were tested at 80deg OAT.

 

Amazing how much room those trucks have up front.

Looks like it is working well!
