Hello = again

I was reading about a company that makes = plenum's for the TSIO550 (for the Lancair 4p). Does anybody have any = experience with this?

I could imagine if you = have a better grip on the temps that this would increase longevity and = would also allow to climb faster if needed.

(I = had a plenum on my TSIO in the Velocity and even a small leak in the = plenum was noticeable, the temps would shot up = high).
