IMPORTANT NOTES:
• Please thoroughly read and understand these instructions before commencing this installation.
• The thread on the cap for the vacuum source is AN#3. The standard swivel nipple can be changed to an AN#3 fitting if desired.
• The Nissan GTR series requires 2 Dual Port BOV kits to replace the 2 standard Bypass valves. Each BOV kit is sold

RECOMMENDATIONS
• Turbosmart recommends that your Blow off valve (BOV) is fitted and adjusted by an appropriately qualified technician
