Aluminium Turbo Blow Off Valve, Recirculating Diverter Dump Valve 25mm/32mm

Upgrade your turbo setup with the Aluminium Turbo Blow Off Valve, a high-performance recirculating diverter valve designed to sharpen throttle response and protect your turbocharger. Crafted from durable aluminium and finished in chrome, this valve channels excess boost back into the intake, reducing lag and keeping your engine’s ECU happy without triggering fault codes. Its universal 32mm inlet connection makes it a versatile addition for a wide range of turbo applications, including Mitsubishi EVO models.

Unlike atmospheric valves, this recirculating design delivers a precise, controlled release with a crisp, metallic lift-off sound that’s noticeable yet refined. It’s engineered for performance and efficiency, helping your turbo recover quickly after shifts and delivering smoother, more responsive power on demand.

The kit includes three tuning springs to fine-tune your boost response across a wide range—from street-friendly to aggressive setups. It’s rated for up to 40 psi, with pressure ranges spanning 5-15 psi, 15-23 psi (installed), and 23-40 psi, so you can tailor the valve to your driving style and modification level. This is the best balance of performance, reliability, and daily drivability for turbocharged engines requiring quiet, consistent boost control.

Benefits & Tips

• Reduce turbo lag and improve throttle response by recirculating excess boost back into the intake.
