So, if you're rocking a Mercedes-Benz SL55 AMG from 2003 to 2008, you might want to check out this PLM 5.5L AMG Heat Exchanger. It’s a solid upgrade that’s been built off our best-selling designs, and trust me, it shows. We’ve made it 25% bigger with our XL version, so you know it’s ready to take on some serious heat.

Now, if you’ve ever pushed your supercharged AMG hard under the sun or during a spirited drive, you know how quickly things can heat up. That’s where this bad boy comes in. By swapping in the upgraded PLM Power Driven heat exchanger, you’re not just playing it safe; you’re keeping your intake charge temperatures in check. This means you can keep that power on tap when you need it most.

What’s really neat about this heat exchanger is its construction. We’ve gone with non-epoxied furnace brazed cores, which means better heat dissipation. Plus, we’ve CNC-welded the aluminum necks for that extra touch of quality. With a fluid capacity of 2.25 liters and a whopping 4000 square inches of fin area, it’s designed to tackle heat soak like a champ.

Installation? Don’t sweat it. You’ll only need some basic hand tools, and the best part is, it mounts right in the stock position. No cutting or modifications necessary. Just a straightforward swap that’ll have you lowering those intake air temps (IAT) in no time. And while you’re at it, since you’ll be removing the bumper, you might as well consider our complete cooling package. For just an extra $100, you get the Johnson pump and Redline water wetter—definitely worth it if you’re serious about keeping your engine cool.

Here are the dimensions if you’re curious:

  • Overall length: 35.5"
  • Core (with end tanks): 28.5"
  • Height: 5.5"
  • Core Thickness: 3" on the XL version
  • Core Thickness: 2.5" on the Standard version

In short, if you want to keep your SL55 running cool and performing at its best, this heat exchanger is a no-brainer. Grab yours today and get ready to hit the road with confidence!

Notes:

  • 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 select SL55 when you place the order.
