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). 

Thanks -- Ronald
