SPA Turbo exhaust manifolds are precision CNC machined from high quality ASTM 536 60-40-18 cast iron.Â
These are ductile spheroidal (aka Nodular iron) castings, where the graphite components are spheroidal in shape and essentially free of other forms of graphite.Â
Specifically designed for pressurized components and high operating temperatures.
In other words, the ideal material for turbo exhaust manifolds; - also used for high quality cylinder liners.
Manufactured exclusively by SPA Turbo and not available anywhere else.Â
In addition, SPA Turbo offers custom machining services and we welcome proprietary product development orders.
We would like to think that we offer outstanding customer service, but recognize there's always room for improvement. We appreciate your input and questions.
SPA Turbo has one of the widest selections of turbo manifolds in the world, including hard to find applications. From log style to top mount equal runners manifolds, we make them and keep them in stock. We have been providing quality performance components since 1990.
