The Mercedes-AMG M156 6.2L V8 is one of the most iconic naturally aspirated engines of all time. With its massive displacement, high-revving character, and raw mechanical sound, it powers some of AMG's most respected models — from the W204 C63 AMG to the SLS AMG. This collection includes every M156 upgrade we offer, with real performance benefits backed by tested fitment across the full AMG lineup.
Every M156 Part We Offer – All In One Place
Whether you're building for track use, street performance, or long-term reliability, our M156 parts catalog includes high-quality bolt-ons and proven tuning support for popular builds like the C63 AMG, E63 AMG, CLS63 AMG, and SL63 AMG. If you're searching for headers for C63 AMG M156 or M156 intake upgrades, you're in the right place.
Here's a full breakdown of the M156 upgrades we carry — tuned for maximum gains on both street and track:
-
M156 Long Tube Headers (with and without midpipes): free up the top end where the 6.2L V8 is most restricted. Gains come from improved exhaust scavenging and reduced backpressure, especially above 5,000 RPM. Expect more high-RPM pull and a cleaner, more aggressive exhaust note — one of the most sought-after M156 performance upgrades.
-
M156 K&N and aFe Power Dry Filters: drop-in high-flow filters that improve intake airflow without drawing hot air from the engine bay. Unlike cone setups, they keep OEM fitment and avoid heat soak — a go-to for anyone comparing C63 AMG intake mods.
-
ROW Airboxes with MAF Sensors: a rare factory upgrade from Euro-spec AMG models. These airboxes flow better than stock while keeping a clean OEM look — great for subtle power gains without going aftermarket.
-
82mm Throttle Body + Adapter Plate: increases airflow past the factory throttle body limit for quicker response and stronger high-RPM pull. Ideal paired with headers or flex fuel.
-
Intake Spacer Kit: adds plenum volume to improve airflow distribution and throttle response, especially at higher RPM. Helps tuning flexibility on builds running headers, cams, or E85.
-
E85 Flex Fuel Conversion Kit: safely run E85 with full sensor feedback and adaptive tuning. Boosts torque and octane tolerance — perfect for high-compression M156 builds.
-
Wavetrac Limited-Slip Differential: consistent traction under load without the harshness of clutch-type diffs. Ideal for drag racing, roll racing, or high-horsepower street builds.
-
Oil Catch Can Kit: captures oil vapors before they re-enter the intake, reducing carbon buildup on valves — a known M156 issue — and helping under high G-forces at the track.
-
3.5L Trunk-Mount Ice Tank: for builds running water-to-air intercooler setups. Adds thermal capacity and allows ice-packing at the track for lower intake temps and repeatable performance.
-
63 AMG 5-Piece Pulley Set: lightweight aluminum pulleys reduce rotating mass for improved throttle response and accessory efficiency — a solid upgrade for high-revving M156 builds.
-
Stainless Steel Brake Lines (W211 E63): improve pedal feel, reduce flex under pressure, and resist fade during repeated hard braking. With added power comes greater stopping demand.
