Cold Air Intake for Mercedes Benz (1997) E420 4.2L Engine

Wake Up Your W210’s M119 V8 with Increased Airflow & Throttle Response

Who It’s For: Designed specifically for 1997 Mercedes-Benz E420 owners running the legendary M119 engine family.

The Problem: The M119 V8 is a masterpiece of engineering, but the factory airbox was designed primarily for noise suppression and luxury-focused silence. The stock plastic housing is prone to heat soak and uses restrictive, corrugated ducting that creates massive air turbulence. This effectively chokes the 4.2L quad-cam V8, preventing it from reaching its full volumetric efficiency.

The Solution: We engineered this intake to eliminate the bottlenecks in the M119 air path. By replacing the baffled factory box with T304 mandrel-bent aluminum piping and a high-velocity filter, we provide a more direct, laminar flow path to the throttle body. This results in a sharper engine note and a noticeable reduction in lag when you tip into the throttle.

Why This is the Ultimate Upgrade

• Enhanced Power Band: Improves horsepower and torque by up to 10% by reducing pumping losses and allowing the M119 to breathe freely at higher RPMs.
• Premium Construction: Built from T304 lightweight aluminum piping which dissipates heat faster than stock plastics and won’t crack or degrade over time.
• Low Maintenance Performance: Includes a high-flow, washable cotton-media filter that only requires servicing every 50,000 miles, eliminating the need for disposable paper filters.
