  • GFB Respons BOV NZ

    GFB Respons Blow Off Valve

    $435.00 – $825.00

    On the surface, the GFB Respons BOV look like just another dual-port blow-off valve, but the GFB Respons is actually much more than that. Featuring GFB’s patented venting bias adjustment system, the GFB Respons allows you to precisely control how much air vents from each of the two outlets.

  • GFB Whistling Trumpet

    GFB Whistling Trumpet

    $54.90

    GFB Whistling Trumpet

    GFB have released the Whistling Trumpets (part # 5701), which emitted a piercing screech when driving aggressively. Unfortunately for a number of GFB owners, the 5701 trumpet only worked with some valve types.

    For the owners of all other types of GFB valves, GFB have now released the 5702 – a modified version of the Whistling Trumpet that is designed to work on low boost applications where the 5701 doesn’t cut it.

  • Subaru Lightweight Pulley Kit

    Lightweight Pulley Kits

    $119.00 – $479.00

    GFB lightweight pulley kits are made from aircraft-grade 6061-T6 aluminium and offer faster acceleration through significant weight reduction on the crankshaft. The effect is similar to a lighter flywheel, and the car feels more lively and willing to rev.

    Most of our kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses. It should be noted that our underdrive pulley kits do NOT adversely affect the operation of the accessories. If they did, we would not sell them!
