Our AMS GT3 intake manifold conversion kit 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 runner diameters than other available factory parts. 49mm, compared to the standard 964 manifold 43mm, or smaller 39mm 3.2 manifolds.
In addition to the standard kit, the turbo version eliminates the factory plastic resonance flap assembly and instead comes with our beautiful CNC machined resonance flap delete kit. This increases reliability, reduces boost leaks and simplifies the whole system. We generally recommend to include the resonance flap, as it can improve power in the mid range on many engines. Many customers chose the resonance flap delete turbo version for the simplicity.
AMS parts are CNC machined and anodised in 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.
