964 993 Manifold bases for GT3 Intakes

964 993 Manifold bases for GT3 Intakes What are they? These 964 993 Manifold bases for GT3 Intakes have been designed for Porsche 964 and 993s that are upgrading to GT3 intake plenums. They adapt any of the 996, 997.1 and 997.2 GT3 plenums to a 964, 993 and 993 turbo. Why do I need these? The GT3 plenums have been hugely popular for performance builds.   They don’t bolt on to the oem base and require these adapters. When you’re putting together an amazing build, the GT3 intake manifold / plenum is a perfect choice.  The manifold bases allow the GT3 plenums to fit like a factory part. The oem plastic bases are prone to failure, cracking and crushing.   These will last a lifetime! Technical Specifications: Designed for OEM fuel rails or aftermarket rails with OEM bolt patterns. Three bolt OEM bolt pattern to the cylinder head. OEM GT3 style rubber coupler connection at the top with proper recess for the rib allowing for turbo / boosted applications. Factory injector boss design for universal fit. 40.5mm port size. Blue or Black anodized for a tough exterior and beautiful appearance. 5 axis machined out of 6061-T6 billet aluminum How many do I need to order? These are sold individually. For a standard 911 engine you’ll require 6. Where can I find more information? Our YouTube Channel is there to enlighten and entertain!   Be sure to check it out!
