GFB blow-off valve accessories Universal T9107 [5925]

GFB blow-off valve accessories with supplier part number 5925.

MACH 2 Atmosphere Upgrade Kit – Convert from Recirculating to Atmosphere Venting Includes: Trumpet for enhanced sound Firmer spring (6115) for optimal performance 25mm hose plug to block the recirc hose The 5925 Atmosphere Conversion Kit allows you to vent the Mach 2 to atmosphere by ensuring the piston stays closed at idle and plugging the recirc hose. This kit includes a 25mm hose plug , a trumpet to replace the hose outlet (amplifying the sound), and a firmer spring (6115) for proper operation. The Mach 2 comes standard with a softer 6116 spring , ideal for recirculating setups or cars with an idle vacuum of 18inHg or less . If the piston remains closed with the stock spring, no change is needed. However, if it hovers open at idle—even with maxed-out pre-load—the firmer 6115 spring should be installed to prevent stalling or backfiring. Compatible with: T9107, T9125
