Collection: M157 Performance Parts for Mercedes E63 AMG / E63S / CLS63 / CLS63S

Unlock serious gains from your W212 E63 / E63S or W218 CLS63 / CLS63S AMG with upgrades built for the M157 5.5L BiTurbo V8.

This platform responds hard to the right bolt-ons — customers routinely see +100 HP and +140 lb-ft with catless downpipes and a proper ECU tune, along with sharper spool and a deeper AMG exhaust note. These parts have been daily-driven, track-tested, and proven on real M157 cars.

Every component in this collection is selected to support higher boost targets, lower IATs, faster throttle response, and consistent drivability — without compromising reliability.

• 🔥 TIG-welded catless downpipes for unrestricted flow and authentic AMG bark
• 🧠 Custom ECU tuning with refined boost/shift strategies and CEL management
• 🧊 Cooling upgrades (heat exchangers, coolant mods) to keep temps controlled
• 💨 High-flow filters & intake spacers to reduce restriction and stabilize IATs

Whether you’re dialing in a street-savvy E63 or pushing a CLS63S for roll-racing, this collection delivers real, repeatable results backed by data — not hype.
