    Very nice looking intercooler.

    This intercooler comes very well packaged and looks well made. I am using this on a Colt I swapped to a 4g63 and this is tight but works very well for short route piping even with a/c and power steering in place. It also tucks in very well under the stock bumper cover after some pretty serious trimming of the steel support and some foam. Idling, my piping is cold to the touch at the TB so it is working well. I have no doubles it will handle the power level I'm going to be throwing at it. Only thing that was a little annoying was the intercooler was drop shipped from Treadstone which took at extra 3 days to ship out. But pricing was good and no issues with the quality of this part.


    Best price here and core is great quality. I got it for my mazdaspeed 3 and it was a perfect fit. Really recommend this core of you buying everything seperate.

    Different but works

    The one I got was not an off the shelf TR6. It had a TR6 core, but it had hacked up "need to make one now" end tanks on it. They took end tanks from a bigger model, cut them down and welded them back together. Then welded the CNC hose ends on. So it doesn't look pretty and half the "treadstone" label is missing but it works fine. If this was a show car then it wouldn't work, but since it's now in my daily driver it works wonderfully. I gave it a 4/5 only because the seller did not notify the customer that it was going to be a modified TR6

    A quality machined intercooler

    I bought this about a month ago and couldn't be happier with it.

    small and efficient

    The TR6 is perfect for my mazdaspeed 6 with stock turbo. It's small and efficient. Fits right in front of the radiator and under crash bar, no need to cut crash bar. Love it!
