⚡ At a Glance
- • Adjustment Precision: Adjustable three-way valve gives fine increments of boost control for tuning
- • Best for: Home tuners and performance enthusiasts working on turbocharged petrol engines
- • Not ideal for: Owners of naturally aspirated cars or those wanting ECU-managed automatic control
Billet aluminium three-way valve enables manual, cabin-mounted boost adjustment with a reliable braking-style control. Universal-fit intent targets most turbocharged petrol engines, while the hard anodised finish resists heat and corrosion.
Precise boost control, thanks to an adjustable three-way valve
The three-way valve uses a calibrated braking-style mechanism to alter boost pressure, allowing the wastegate or actuator to be adjusted manually. Mechanical linkage and a fine adjustment screw deliver predictable changes to turbine pressure.
Fine increments of boost can be dialled in for sharper throttle response and smoother power delivery, especially useful during tuning sessions or spirited driving.
Durable construction, with billet aluminium and hard anodised finish
Machined from billet aluminium and finished with a hard anodise, the housing resists high temperatures and slows oxidation and corrosion under heat stress. The metal construction keeps tolerances stable under repeated adjustments.
Long-lasting hardware means fewer replacements and reliable operation in engine bays or cabin locations that experience elevated temperatures.
Easy access for live adjustments, with cabin mounting design
Designed for inside-cabin installation, the unit places the control within easy reach while driving or testing, rather than under the bonnet. The universal mounting approach and simple fittings streamline DIY installation.
Quick access to boost settings makes on-the-fly tuning practical, and straightforward fitting suits home mechanics and enthusiast installers.
