Performance Air Spacer Kit for Mercedes Benz (2007-2011) M156 6.2L Engine E63 SL63 CLS63 S63 AMG

Boost your M156 6.2L AMG's performance with this precision-engineered air spacer kit. Proven dyno-tested gains of 23-25 HP at the rear wheels through improved airflow—all while keeping your engine bay looking factory-fresh.

More Air In, More Power Out—Without the Intake Clutter

The M156 6.2L naturally aspirated V8 is already a masterpiece—Mercedes-AMG's hand-built tribute to raw, unfiltered power. Found in the W211 E63, R230 SL63, C219 CLS63, and W221 S63 from 2007-2011, this engine delivered something special: 518 HP of naturally aspirated fury with a soundtrack that still gives goosebumps. But there's a catch. The factory airbox design chokes airflow by positioning filters directly over restrictive inlets, limiting flow to just 55% of potential capacity.

This Performance Air Spacer Kit fixes that engineering oversight with German precision. By lifting the filters away from the restrictive inlet area and opening up the underside by 50%, you're giving your M156 what it's been begging for—over 30% more airflow. The result? Dyno-verified gains of 23-25 rear-wheel horsepower on stock-tuned motors, with even higher numbers on tuned setups.

Key Features at a Glance

• Increased Airflow: Over 30% improvement in air delivery to your M156 engine
• Proven Power Gains: Dyno-tested 23-25 HP increase at the rear wheels on stock motors
• OEM Integration: Blood red anodized aluminum spacers with German-made stainless hardware
• Filter Flexibility: Works with factory filters or high-flow aftermarket options for maximum gains

Installation & Fitment

This is a straightforward bolt-on upgrade that takes the mystery out of intake modifications. Unlike messy open-element intakes that expose your engine to heat soak and dirt, this kit maintains the factory airbox configuration while dramatically improving performance. All aluminum brackets, spacers, and stainless steel German hardware are included. Your engine covers mount back exactly as Mercedes intended—just with serious power underneath.

Why Aluminum and Precision Hardware Matter

High-quality anodized aluminum resists heat and corrosion in the demanding environment of an AMG engine bay. The blood red finish isn't just for looks—it's a durable, hard-anodized coating that handles temperature extremes. German-made stainless steel hardware ensures proper torque specs and longevity, because a performance part is only as good as what holds it together.
