Our customers love our GT3 intake manifold conversion kit suitable for the classic Porsches. True to our namesake, it is available in a range of customised configurations and combinations of parts.
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.
Available with our beautiful CNC machined resonance flap kit. This uses sealed roller bearings for longevity and turbo applications. We recommend to use our resonance flap kit with turbo builds as well, results show on many applications improvements to the mid range. This is highly dependent on each engine and selected components. Some customers prefer the simplicity of our turbo kit, with resonance flap delete for turbo cars.
AMS parts are CNC machined and anodised black.
The kits are available to suit both the earlier 2 bolt cylinder heads (2.7/3.0/3.2) and later 3 bolt cylinder heads (964/993), please select the right option for you. We are happy to help and build custom kits to suit your needs. Please don't hesitate to contact us!
**GT3 manifolds currently on backorder, please contact us prior to ordering kits that include manifolds. Porsche have increased manifold costs 400% in the past year. We are working on our own manifold solutions.
