Product Description

The Snow Performance 102mm LS Throttle Body Injection Plate is the ideal solution for adding water-methanol injection to high-performance LS engine builds without permanently modifying your intake manifold. Designed to mount between the throttle body and intake manifold, this billet aluminum injection plate provides an even distribution of water-methanol across all cylinders, helping reduce intake air temperatures, suppress detonation, and support increased horsepower on naturally aspirated, supercharged, and turbocharged applications.

Unlike single-nozzle charge pipe installations, the throttle body injection plate introduces the water-methanol mixture directly into the intake stream for improved atomization and cylinder-to-cylinder distribution. This results in more consistent cooling, improved combustion efficiency, and the ability to safely run more ignition timing or boost when paired with the proper tuning. Whether you're building a street-driven Corvette, Camaro, or a dedicated race car, the Snow Performance injection plate is a clean, reliable solution for maximizing engine performance.

Manufactured from CNC-machined billet aluminum, this plate installs easily between your existing 102mm throttle body and intake manifold, making it an excellent upgrade for high-horsepower LS platforms.

Product Features

  • Simple Water-Methanol Integration – Adds methanol injection without drilling or modifying the intake manifold.
  • Lower Intake Air Temperatures – Helps reduce heat soak and improve power consistency under boost.
  • Supports Higher Power Levels – Allows for more aggressive ignition timing and increased boost when properly tuned.
  • Precision Billet Construction – CNC-machined from high-quality aluminum for exceptional durability and sealing.
  • Excellent Atomization – Injection point promotes even distribution across the intake tract.
  • Direct Bolt-On Installation – Fits between the throttle body and intake manifold with minimal installation effort.

Why Upgrade?

As horsepower and boost increase, intake air temperatures become one of the biggest obstacles to making safe, repeatable power. Water-methanol injection is one of the most effective ways to combat heat soak while improving knock resistance, and the Snow Performance 102mm Injection Plate provides a clean, professional installation that doesn't require permanent modifications to your intake manifold.
