Alta 'Stiffy' Blow-Off Valve Spring (Gen 2)

SKU
AMP-TAC-100
£20.00 £16.67

The Alta Blow-Off Valve (BOV) upgraded spring is a brilliant way of allowing your MINI to hold more boost between gear changes. The stiffer spring works as the OEM item does at gentle throttle however under hard acceleration it will retain more pressure in the boost hoses when you are changing gear leading to a more responsive car and less turbo lag.

Alta have tested their spring up to 40psi (more boost than you could ever need) without any signs of fatigue or failure and state that the Custom Made Heat treated 17-7 Stainless Steel can survive over 7 million cycles.

The spring is stiffer than the JCW item and thus is geared towards owners that are running higher boost pressures than standard. Easy installation makes this not only cost effective but also brilliant value for money.
