Cast Aluminum Plenum upgrade for Porsche 911 997.1 TURBO/GT2

SPA Performance has developed a must have for 911 Turbo (997.1) builders

The stock plenum is made out of plastic, which may work well for the stock engine, but when it comes to getting more out of this engine, this may be a limiting factor.

With that in mind, SPA Performance has developed a plenum 100% made of cast aluminum, with 5mm wall thickness, which will allow builders to work further on this engine, with no worries regarding the plenum's integrity.

The plenum was designed to work with an 82mm throttle body (not included in the product), standard on the Porsche 911 997 GT3, which ensures greater flow for the set.

Stock hoses and clamps (not included) must be used to fix the manifolds and plenum.

 Application: Porsche 911 Generation 997.1 Turbo and GT2 (3.8)

Material: cast aluminum 

Contents: 1 plenum.

Plenum ports: 1/8" NPT.
