Haysuz here in for a FLUIDYNE Heat Exchanger install on his beautiful Renaissance Red A90 Supra. While this modification is well hidden, it not only helps keep intake air temps down, it also increases fluid capacity by 40%. As most A90 owners know once these cars are tuned they are prone to heat soak or even entering limp mode very fast. For example Haysuz having a catless downpipe and being on a E50 Tune by F80 Paul he would experience heat soak after about 2 or 3 solid pulls, with a noticeable power loss due to temps. The heat exchanger upgrade itself utilizes CNC fittings designed to connect to your factory system. It also comes with mounts for your OEM transmission cooler so you can keep the stock lines in place making it a complete oem drop in replacement. This is definitely on our list for most recommended modification guaranteed.
