Product Overview
The Snow Performance Stage 3 Boost Cooler delivers true 2D-mapped water-methanol injection for modern direct-injected and forced-induction engines. By referencing both boost pressure and fuel pressure, the system creates a dynamic injection map that delivers the precise amount of water-methanol exactly when the engine needs it.
Using fuel pressure as a second input allows the injection curve to extend beyond fixed boost points, providing greater control and a broader operating range for high-performance applications.
The non-invasive Stage 3 controller mounts directly to the steering column or dash, eliminating the need for additional gauge pods while combining multiple functions into a single compact unit. The controller operates as a boost gauge, progressive water-methanol controller, and fuel system monitor, giving you real-time visibility and control.
The Stage 3 Boost Cooler is proven to reduce intake air temperatures by up to 100°F and increase effective octane by up to 25 points, allowing for greater power, improved detonation resistance, and more consistent performance under boost.
Each kit includes the adjustable Stage 3 controller, 4AN fittings, and stainless braided line for engine-bay pump and tank mounting.
For trunk-mount configurations, see Part #SNO-40014-BRD or #SNO-40012-BRD.
