So, you already have a beautiful and expensive individual throttle body kit, but, you would like to add a set of 996 GT3 intake plenums and resonance flap to the engine package! We have you covered.

Introducing our ITB GT3 kit. The kits are based around the 996 GT3 large volume intake manifolds, with much larger port diameters than other available factory parts. 49mm, compared to the standard 964 manifold 43mm, or smaller 39mm 3.2 manifolds.

We work with you to design and manufacture adapters for your ITBs to direct mount the intake manifolds. Lead time is generally 6 weeks for production of the parts.

Available with with our beautiful CNC machined resonance flap kit (photos not shown yet). This uses sealed roller bearings for longevity.

AMS parts are CNC machined and anodised black.
