Mercedes-Benz SL Intercooler Replacement Parts

Only certain SL variants have an intercooler — specifically those fitted with turbocharged or supercharged engines, such as the SL55 AMG (supercharged V8), SL63 AMG, and the turbocharged six-cylinder and eight-cylinder engines found in later generations like the R231 (2012–2022); naturally aspirated SL variants such as the earlier SL500 or SL600 V12 do not use an intercooler at all. If you are unsure whether your SL is turbocharged or supercharged, the quickest check is your engine code, which appears on your V5C or via a VIN check. Searching for an intercooler on the wrong variant will draw a blank, so confirm your engine code before requesting quotes from a breaker.

The Mercedes-Benz SL R231 ran from 2012 to 2022 and received a significant facelift in 2016, which brought engine and ancillary updates to several variants. Whether an intercooler from a 2012–2015 R231 crosses cleanly to a 2016-on R231 depends on whether the engine code changed across that facelift boundary — where the engine code is identical, fitment is far more likely. However, ancillary and mounting changes mid-production mean you should confirm compatibility with the breaker against your exact registration rather than assuming year-range alone is sufficient.

Trim level as a badge (SL400, SL500, SL63 AMG, and so on) broadly reflects the engine fitted, and it is the engine code — not the badge name — that determines intercooler fitment. An SL400 and an SL500 from the same generation carry different engines with different specifications, so their intercoolers are not interchangeable; conversely, two cars wearing the same badge with the same engine code are far more likely to share the part. Always supply your engine code to the breaker rather than just the trim badge, as badge names have sometimes been reused across generations on different engines.

The R230 SL (2001–2012) and R231 SL (2012–2022) are entirely different generations with different bodyshells and engine architectures, and the supercharged V8 in the R230 SL55 AMG is a distinct unit from the turbocharged engines used in R231 AMG variants. Intercoolers are engine-specific in their dimensions, pipework routing, and mounting points, so a direct swap between generations is very unlikely to be compatible. Stick to sourcing an intercooler matched to your exact engine code, and confirm the part number with the breaker against your registration.

Naturally aspirated engines do not use forced induction, so they have no turbocharger or supercharger to generate the compressed, heat-affected air that an intercooler is designed to cool — the part simply does not exist on those variants. Earlier SL models such as the R129 and many R230 and R231 naturally aspirated versions fall into this category. If you are chasing a cooling-related problem on a naturally aspirated SL, the part you may actually need is a radiator, oil cooler, or coolant expansion tank rather than an intercooler.
