SNYFT 3-Port Boost Control Solenoid Valve Replacement for MAC 35A-Series — High-Flow, IP67 Waterproof Stainless Internals

SNYFT's 3-port boost control solenoid valve is a direct, high-flow replacement for MAC 35A-series valves designed to restore precise turbo boost control with a 5ms electronic response.

Engineers and tuners designed this valve to match the fit, form and function of MAC 35A-series units while improving flow and durability for modern turbocharged engines. It uses pulse-width modulation (PWM) and stainless internals in an IP67-rated housing to deliver fast, repeatable boost control in harsh under-hood environments. The unit is wire-ready with 18" flying leads and standardized 1/8" BSPP ports to simplify retrofit or service work.

How does this valve replace a MAC 35A-series unit without modification?

The SNYFT valve mirrors the mounting, electrical and porting layout needed for direct swap-in replacements of MAC 35A-style valves. That minimizes downtime and avoids custom fittings or harness changes.

• Standard 1/8" BSPP ports match MAC plumbing threads
• 18" flying leads for straightforward electrical connection
• Form and mounting points aligned for bolt-in replacement

What performance improvements can I expect on spool-up and boost control?

With a high-flow internal path and PWM control tuned for a 5ms actuation, the valve reduces lag in boost transitions and holds pressure more consistently under load. This yields crisper throttle response and cleaner boost curves during aggressive driving or tuning.

• 5ms response helps faster compressor spool-up compared to slower solenoids
• High-flow design reduces pressure drop at the control port
• Stable PWM control for repeatable boost setpoints during transients

Will this valve survive under-hood heat, dirt and moisture?

Yes. The SNYFT valve is built with stainless steel internal components and an IP67-rated sealed enclosure to withstand water exposure and particulates. It’s specified for wide temperature ranges and elevated pressure environments found in performance applications.

• IP67 waterproof rating protects electronics from wet conditions
• Operating range designed for extremes common under the hood
• Stainless internals resist corrosion for long service life

What comes in the box and what certifications support this product?

The valve ships with the hardware needed to get it running out of the box and is produced under quality-controlled processes. A multi-year warranty covers manufacturing defects, giving technicians and owners confidence in installation and longevity.

• Includes valve, springs and a screwdriver for adjustments
• Manufactured under ISO 9001-aligned processes
• Backed by a 3-year limited warranty for peace of mind

Who is this for: The SNYFT 3-port boost control solenoid is aimed at professional mechanics, tuners and performance-minded vehicle owners who need a reliable MAC-compatible replacement or an upgrade for turbo and supercharger boost management. It fits anyone seeking faster actuator response, robust environmental protection and a straightforward bolt-in installation for Garrett, BorgWarner and similar systems.
