Wagner Tuning Performance Intercooler Kit — F80/F82/F87 M2/M3/M4 S55

The aluminum end tanks aren't just upsized stock parts — they were designed from scratch in CAD and refined through CFD simulation to ensure the internal airflow path is as clean and unrestricted as possible. The result is a unit that pulls heat out of your charge air aggressively without introducing meaningful back pressure. Wagner Tuning finishes every intercooler core with a thermally conductive anti-corrosion coating, which serves double duty: it protects the core against the elements and keeps thermal transfer properties consistent over thousands of miles, not just on day one.

On track or on a long back road pull, heat soak is what turns a great car into an inconsistent one. This intercooler directly addresses that, keeping charge air temperatures stable under repeated hard runs so your S55 delivers the same power on lap five as it did on lap one. It's equally effective on a street-driven M4 running pump gas or a tuned M2 Competition on E85 — the core has the capacity to handle whatever you're throwing at it.

Installation is fully plug-and-play with no cutting, fabrication, or custom plumbing needed. The kit includes detailed instructions, making it a realistic home-garage install for anyone comfortable with basic hand tools. The machined WT logo on the end tank is a nice finishing touch that signals you didn't just bolt on any intercooler — you went straight to one of Europe's foremost forced-induction specialists.
