Weistec WMI Kit Mercedes-Benz A45 AMG S | A45 AMG 2019-2024
$1600.00
Water/Methanol Injection was originally used to reduce knock while increasing power and performance in aircraft engines and eventually came to be used in the motorsport industry where it was found to have substantial benefits on turbocharged engines. The Weistec Water-Methanol Injection System provides substantial cooling and knock-prevention benefits for the M139 engine helping improve consistency and performance. The combination of the cooling effects of methanol and the knock resistance of water results in significant gains (through improved cooling and octane) in horsepower and torque.

Weistec has engineered and manufactured many of the components of this system to ensure a simple and straightforward installation that a universal kit simply lacks. This system is a complete bolt-on system that can be installed without any guesswork or custom fabrication. The gains in performance paired with its consistency, makes this an essential upgrade for the M139 engine.



Features:
  • Reduced Intake Air Temperatures
  • Increased Knock/Detonation Resistance
  • 20-80 HP Gain
  • 60-61 Aluminum charge pipe with intergraded injector ports

What Is Weistec Engineering?

Based out of Orange County, California, Weistec Engineering is an industry leader in research, development, and design. While the company was only established in late 2010, founder Michael Weiss and his partner Steve Atneyel both have an impressive track record of working with some of the fastest and most powerful vehicles in the world. The duo were both engineers for major American OEM and aftermarket performance companies; Michael was involved with advanced engineering, while Steve specialized in computer calibration.

Michael Weiss and Steve Atneyel decided to branch out on their own and combine their expertise and experience.
