Treadstone TR8 intercooler in Volvo S60R T6 hybrid k16 turbo

Very efficient intercooler core. Treadstone TR8 intercooler was installed in Volvo S60R T6 hybrid k16 turbo 430hp project. With stock intercooler there was 65C temperature. After installing Treadstone TR8 intercooler temperate drops down to 45C.

Best modification I've done, so far!

I bought this TR8 for my 2013 Audi Allroad. My intial impressions are its awesome! The TR8 arrived, double-boxed with enough foam padding to keep it afloat should the cargo plane go down! #Castaway

The intercooler is really well made, with beautiful welds and it's far more efficient than the cheaply made OE Audi one w/ plastic end caps.

Install is custom, so be handy and use angle / stock from a hardware store - Home Depot had all I needed to mount it. As for the piping, you may need to source tubing specific for your needs.

As for performance, the engine breathes freely, throttle response has improved dramatically and definitely feels more powerful off the line and while in passing others.

Next up is an ECU tune to get the most performance out of it- definitely would recommend this install!

Great intercooler, Happy with Purchase

Very happy with the Treadstone TR8 I ordered. Very well made, super clean welds. Inner fin work is perfect. Bought this to replace a lower class intercooler and this is perfect. Dimensions were exact, packaging was great and came without a flaw on it. I would recommend and would order again if I needed to.

Super quality

The article has an exact description, adequate photos and an impeccable quality in the packaging process. I definitely recommend the page, since they have excellent prices and a super fast service. Thank you

Will be helpful in the summer

The quality is nice, best bang for the buck deal I could have found for such an intercooler. Installed on a 2012 A4 B8, nice fit right behind the crashbar.
