Thumbs up H6 Phenolic Thermal Manifold Spacer

Sorry to double post, but anyone be interested in one for their swapped rides? Trying to see if enough interest for a group buy or start production on them. "Thermal spacers lift the intake manifold off the super heated engine to lessen the transfer of heat. Both the intake manifold and engine block are aluminum so the high heat transfers very quickly....well these spacers stop that. The cooler the intake charge the more HP and TQ your engine will make.

In addition to cooling your intake charge, these will also give you larger intake volume similar to that of a throttle body spacer."

I could see this being useful for the EZ30D or EG33 aluminum manifolds, but I don't know about the EZ30R. It already has the plastic manifold, which cuts down on intake temps. Would spacers really help at all?

I think there would be minimal gains, if any at all, using phenolic spacers with a plastic intake manifold. My understanding is that the plastic manifolds aren't much above ambient temp when you touch them after driving, as opposed to a heat-soaked aluminum manifold that is hot to the touch.
