This direct OEM replacement is precision-machined from aircraft-grade T6061 billet aluminium and fully compatible with OEM electronics. Designed for reliability up to 600 HP (with uprated spring kit), it features a fully serviceable piston with heat-stabilised Viton O-rings and all internal and external components manufactured in the UK. Lubricated with high-temperature Mobil1 grease, the unit is rebuildable in minutes and produces no check engine lights (EML). Performance benefits include improved dynamic throttle response, consistent turbo boost, and reduced turbo lag. Backed by a lifetime warranty, this component offers long-term durability and serviceability.

A full replacement atmospheric blow-off valve (i.e. noisy) that integrates seamlessly with the OEM electronics and results in no detriment in performance, and absolutely NO fault codes or check engine lights.

The valve increases the throttle response during gear changes by reducing turbo lag. It has been designed to help the turbocharger maintain its rotational speed ready for when you accelerate, whilst also taking the strain away from the impeller. Without removing this stress from your turbo, it could cause premature failure, especially on tuned engines and modified vehicles.

It has a very short overall installed height, which enables fitment of this atmospheric valve into the tight space between the turbo and the inlet hose from the airfilter, older larger valves and sandwich plates will not fit this engine.
