PLM Mercedes Benz 5.5L AMG Heat Exchanger for E55 CLS55 SL55 is now 25% bigger in our XL Extra Large version.

Like our standard sized version, it still mounts in stock position. Supercharged Mercedes AMG's tend to overheat under hot weather or extreme driving conditions. If you increase boost or horsepower, expect your intake charge temp to rise even further. The solution is to add the upgraded PLM Private Label Mfg. Power Driven heat exchanger. This heat exchanger will significantly reduce intake charge temps allowing you to keep power when needed. The PLM Power Driven heat exchangers use non-epoxied furnace brazed cores resulting in better heat dissipation and are welded with CNC precision machined aluminum necks. It has a 2.25 liter fluid capacity and 4000 square inches of fin area to help battle heat soak issues!

Installation requires basic hand tools and is the only heat exchanger on the market that's affordable & does not require any cutting or modifications to vehicle to install. Get it today and lower the temperature!

25% Bigger in this "XL" Extra Large version.

This cooling kit includes:

PLM Mercedes Benz 5.5L AMG Heat Exchanger "XL" Extra Large Version
Johnson Pump CM30 with wire harness
Redline Water Wetter (Coolant Additives)

Installation Note:

The side brackets on our heat exchangers are made to bolt-on to E55. If you have a CLS55 or SL55, you will need to make 2 new holes on our brackets. There is no modification to your car as the installation is still bolt-on.
On the SL55, because one of the hose connection is on the driver side, you will need a longer hose. We are happy to provide the hose at no extra cost if you have a SL55, just let us know when you place the order in the notes.
