Porsche 718 Cayman & Boxster Water–Methanol Injection Kit – Snow Performance 2.5 Boost Cooler

Charge Cooling & Knock Protection for High-Boost Porsche 718 Builds

Unlock 50–70+ HP with Water-Methanol Injection for Your 718

The Snow Performance 2.5 Boost Cooler Water–Methanol Injection Kit is a proven charge-air cooling solution for the Porsche 718 Cayman & Boxster, designed to reduce intake air temperatures, suppress knock, and increase tuning safety under boost. Built for tuned, high-output, and track-driven 718 builds, it delivers consistent power and added protection where factory cooling reaches its limits.

This is a functional performance system—not a gimmick—used across motorsports to manage heat and detonation in turbocharged applications.

Why This Water–Methanol Injection Kit Exists

As boost pressure increases on the Porsche 718 platform, intake air temperatures rise rapidly. Heat soak leads to power loss, timing pull, and increased knock risk—especially during aggressive street driving or sustained track sessions.

The Snow Performance 2.5 Boost Cooler system was developed to directly address these limitations by injecting a precisely metered water–methanol mixture under boost. This lowers charge temperatures, increases effective octane, and stabilizes combustion, allowing safer and more repeatable performance at higher power levels.

Key Features & Benefits

• ‍Significant Intake Air Temperature Reduction — Improves charge cooling under boost
• ‍Increased Knock Resistance — Raises effective octane for safer high-boost operation
• ‍Boost-Referenced Progressive Injection — Flow scales with engine load
• ‍Improved Power Consistency — Reduces heat soak during repeated pulls or track use
• ‍Stainless Braided Lines & 4AN Fittings — Durable plumbing for long-term reliability
  

Performance-Focused Engineering

Charge Cooling Where It Matters

By injecting a fine mist into the intake tract, the system absorbs heat as it vaporizes, dramatically lowering intake air temperatures. Cooler, denser air supports more stable ignition timing and improved efficiency under sustained boost.

Expanded Tuning Headroom

Methanol increases knock resistance during combustion. When calibrated correctly, this allows tuners to safely optimize boost and ignition strategies—especially beneficial on upgraded turbo or high-load setups.

Who This Is For

Ideal for Porsche 718 Cayman & Boxster owners building:

• Tuned street cars
• Higher-boost turbo setups
• Track-driven or heat-soak-prone cars
• Performance builds requiring added knock protection

This system is best suited for drivers prioritizing safe, consistent power, not inflated dyno numbers.

Installation & Tuning Notes

Professional installation is strongly recommended.
Custom ECU tuning is required to safely integrate water–methanol injection into the engine calibration.

Always consult your tuner prior to installation to confirm injection strategy, fluid ratios, and fail-safe configuration.
