HEAT EXCHANGER GROUP BUY - E55, SL55, CLS55

Before installing it my IATs hovered around 25-30 degrees above ambient, afterwards I see 15-20 above ambient. These are crusing on the freeway numbers in 85-95 degree heat running an 80mm FSP. The only change was installing this HE. Also recovery times are drastically improved but I did not log any of that so I don't have any numbers tho throw out.

I'll add for reference: Engine temp is 190-195f. and transmission sits at 175-180f.
0-80 pull at nearly full throttle sends my IAT up to 102-105, and in 30 seconds its back into 95~f range, and then a minute later 90~f (coming off STAR monitoring).

IAT shouldn't ever be above 100f except after a pull.

There's something wrong with your car then. With stock setup on my CLS55, I'm running IAT of 10f over ambient (85f) in high Florida humidity mid-summer with the newer Bosch 010 pump installed.

I bought one from Shardul a few months ago. Very easy to install. There are some great instructions by bbirdwell and I added a couple of pointers as well from my experience but not having to drill anything or worry about the oil cooler definitely makes this a great choice.
