ZZP LSJ S3 Cobalt Heat Exchanger


ZZP is proud to bring to you another manufactured in house aluminum heat exchanger(radiator) for your LSJ car. The LSJ engine uses a M62 supercharger to add boost and the LSJ lower intake has a laminova style intercooler system built into it. The car comes from the factory with a Bosch intercooler pump which cycles water from the heat exchanger through the laminova cores and back. This will cool the outlet air from the supercharger. The factory exchanger is small and doesn't hold very much coolant, the ZZP unit is larger and holds more coolant and in turn will keep your boost temps down resulting in more power.

This unit is made to work with your factory intercooler although it could be used to replace the factory one. It is not affected by the installation of a dual pass kit and works with or without dual pass. The unit installs by removing one hose from the factory cooler and going into this one. Then you go out of this cooler, into the factory cooler on the fitting where you removed the hose.

It now comes with our new ZZP logo in black.

Front Mount HE

Bought my front mount second hand from a friend. Got it installed on my car without having to drill any holes. I used the two holes on the bottom of the crash bar to mount then had to flex the side mounts on it to get it to mount up properly. Took me a little time but it looks great in the front of my car.

Item is as described

Installation was unique b/c I bought this for my DF Goblin; however, the H.E. was as described with nice clean welds and packaging that allowed it to get here without denting of the fins.
