SNYFT 3-Port Boost Control Solenoid Valve - MAC 35A Direct Replacement, High-Flow PWM, IP67

The SNYFT 3 Port Boost Control Solenoid Valve is a direct, high-flow replacement for MAC 35A-series valves that restores precise electronic boost control and fast response for turbocharged engines.

If your turbo system has been hamstrung by a failing boost solenoid or you need a dependable upgrade that fits MAC-style installations, this SNYFT unit delivers an OEM-style fit with performance improvements. Designed for 12V systems and built to handle demanding under-hood conditions, it replaces MAC Valve 35A models without modification and brings faster spool response, higher flow capacity, and rugged weatherproofing.

How does this solenoid improve throttle response?

The SNYFT valve uses pulse-width modulation (PWM) and a high-flow internal path to change actuator pressure quickly and accurately. The result is a substantially faster spool-up and reduced lag compared with many stock solenoids.

• 5 ms electrical response time for near-instant actuation
• High-flow internal design to move pressure faster to the wastegate
• PW modulation for precise, repeatable boost steps at varying engine loads

Will it fit my MAC 35A-series plumbing and wiring?

Yes — the SNYFT valve is engineered as a direct replacement for MAC 35A-series units, matching port size, mounting footprint, and electrical connector style so you can swap it in with minimal effort. Included flying leads and standardized 1/8" BSPP ports make installation straightforward.

• 1/8" BSPP ports compatible with common MAC lines and fittings
• 18" flying leads for flexible wiring during swap or retrofit
• Mounting footprint and spring set designed to match the MAC 35A geometry

How durable is the valve in harsh environments?

This solenoid is built for under-hood service where heat, moisture, and vibration are routine. It combines stainless-steel internals with an IP67-rated sealed housing to resist moisture ingress and maintain reliable operation across wide temperature ranges.

• IP67-rated enclosure for dust and temporary immersion resistance
• Operating range from -0°F to 250°F and pressure tolerance up to 120 PSI
• Stainless steel internal components for corrosion resistance

What comes in the box and what support is provided?

The SNYFT kit includes everything needed to perform a clean replacement or upgrade: the solenoid valve, matched springs, and a screwdriver for basic adjustments. The product is manufactured under ISO 9001 processes and backed by a multi-year warranty for added confidence.

• Complete package: valve, springs, screwdriver included
• ISO 9001 manufacturing and 3-year limited warranty
• Compatibility notes for Garrett, BorgWarner, and other turbo systems

Who is this for: Technicians, tuners, and enthusiasts who need a reliable, drop-in replacement for MAC 35A-series boost solenoids or want to improve boost stability and spool response without reworking plumbing or controllers. If you maintain or modify turbocharged vehicles — from daily drivers to track cars — and require a robust, fast-acting boost control solution that installs easily, the SNYFT 3 Port Boost Control Solenoid Valve is designed for your needs.
