Alta OEM BOV Spring Upgrade Mini Cooper S R56 07+

The ALTA BOV Spring Upgrade is a better alternative to the more expensive complete replacement BOVs other competitors sell. ALTA took this a step further and created this simpler, better performing spring upgrade that is an upgrade for both JCW and MCS models! The ALTA BOV Spring Upgrade for your stock Blow Off Valve (BOV) is a very effective way to make your turbocharged Mini hold more boost between shifts reducing turbo lag.

This stiffer spring allows the BOV to function normally during normal operations, but, but keeps more pressure in the boost tubes making it feel much faster shifting. Anyone with proper tools can install this part in under 30 minutes. Simply remove a couple OEM parts, remove the electrionic BOV and replace spring with the ALTA spring and your done!
