Mercedes M156 Performance Parts – C63, E63, S63, CLS63 AMG

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 all available M156 parts we offer — tuned for maximum gains on both street and track:

• M156 Long Tube Headers (with and without midpipes): 
  These 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. This is one of the most sought-after M156 performance upgrades. 🔧 View Product
• M156 K&N and aFe Power Dry Filters: These drop-in high-flow filters improve intake airflow without drawing hot air from the engine bay. Unlike cone setups, they maintain OEM fitment and avoid heat soak. A go-to upgrade for anyone comparing C63 AMG intake mods or searching best air filter for M156. 🔧 View Product
• 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. A top choice for those searching ROW airbox C63 AMG or OEM+ M156 intake upgrade. 🔧 View Product

• 82mm Throttle Body + Adapter Plate: Increases airflow past the factory throttle body limit for quicker throttle response and stronger high-RPM pull. Ideal when paired with headers or flex fuel. Commonly searched as M156 82mm throttle body upgrade or C63 AMG big throttle body. 🔧 View Product
• Intake Spacer Kit: Adds plenum volume to improve airflow distribution and throttle response, especially in higher RPM ranges. Helps with tuning flexibility on builds running headers, cams, or E85. Often searched as M156 intake manifold spacer or C63 AMG plenum upgrade. 🔧 View Product
• E85 Flex Fuel Conversion Kit: Lets you safely run E85 with full sensor feedback and adaptive tuning. Boosts torque and octane tolerance — perfect for high-compression M156 builds. Searched often as M156 E85 tune, C63 AMG flex fuel kit, or AMG 6.2 ethanol conversion. 🔧 View Product
• Wavetrac Limited-Slip Differential: Delivers consistent traction under load without the harshness of clutch-type diffs. Whether you're building a 10-second C63, pushing the limits on track, or just want better street grip, Wavetrac keeps both wheels putting down power. Ideal for drag racing, roll racing, or high-horsepower street builds. Frequently searched as C63 AMG LSD upgrade, M156 drag differential, or AMG 6.2 rear end upgrade. 🔧 View Product
• Oil Catch Can Kit: Captures oil vapors before they re-enter the intake, reducing carbon buildup on valves — a known issue on the M156. Also helps under high G-forces at the track or drag strip by preventing excess crankcase pressure and oil mist from contaminating the intake system. Common search terms: best oil catch can for M156, C63 AMG PCV solution, AMG 6.2 track prep. 🔧 View Product
• 3.5L Trunk-Mount Ice Tank: Designed for builds running water-to-air intercooler setups — especially supercharged or high heat-load configurations. Adds thermal capacity and allows ice-packing at the track for lower intake temps and repeatable performance. Commonly used on drag builds and roll racing setups. Search terms include M156 ice tank, C63 AMG trunk water tank, and supercharged AMG cooling upgrade. 🔧 View Product
• 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 looking to free up power without affecting reliability. Frequently searched as C63 AMG lightweight pulley kit or M156 underdrive pulley upgrade. 🔧 View Product
• Stainless Steel Brake Lines (W211 E63): With added power comes greater stopping demand. These lines improve pedal feel, reduce flex under pressure, and resist fade during repeated hard braking — A go-to upgrade for anyone searching E63 AMG brake line upgrade or W211 stainless steel braided lines. 🔧 View Product
