This part does not affect the base vehicle warranty.
The mountune uprated turbo re-circulating valve (TRV) is a direct replacement for the OE component.
Machined from solid aluminium with a piston-type design (compared to the OE diaphragm) the more robust design and material are suitable for vehicles in advanced state of tune.
A diaphragm-design recirculation valve could function less effectively when the pressure differential across the turbocharger compressor housing is increased above the original operating conditions. This can cause the valve to open prematurely, leading to possible turbocharger damage due to increased turbo shaft speed.
During development, with increased boost pressure, compressor-out temperatures were seen to exceed the safe operating limit of the OE valve. The mountune Mk3 Focus RS TRV is engineered to withstand much greater temperatures whilst maintaining performance, making it an essential upgrade for cars running increased boost pressure.
A Quality,Product,a must have purchase for any rs owner.would highly,recommend.
The Valve is really good quality, fits perfect. The install took me about 20 minutes. Would recommend!
Bought from the online store. No issues at all in purchasing, was able to pay using paypal which I liked. Dispatched quickly aswell given the amount of orders these guys must process. The valve its self was my first purchase from their store. Compliments the induction filter I have fitted. I'm almost certain the valve alters the noise but it sounds awesome to me. A million miles better quality than the standard valve anyway. Well worth it in my opinion
