Yep. I notice it only shows 16 bolts, but I've found this to be a common type of error in the catalog.

From the illustrated parts list:

Bolts: AN3C-4A
Washers: AN960-10L
Nuts: MS21043-3

It'll be tricky modifying any of those those pipes. They are only solidly mounted at the cylinder heads and are just sort of rammed against the seals where the airflow transitions from the engine sump to the pipes. This is a location where air leaks can develop.

It's hard to be sure from the pictures but the chrome intake pipes seem to me to have a different shape than stock. The no. 1 pipe looks to start the bend toward the rear slightly further from the cylinder head and not completing quite as many degrees of bend. Could these pipes be 3rd party parts? Y...

The engine was overhauled 50 hours ago by a big shop in Florida (previous owner). At the overhaul it got the Hartzell prop via the STC. Logs are at the plane to see if it got new intakes at the same time. No side loads...it's an honest "barely" touching...just at the slip joint. Steve, yo...

Spark plug routing is also not original and of course it's not the original prop. There is definitely some tinkering evident.

If they're touching that's not good, as they might be more than just touching but actually placing lateral loads on each other. There does seem to be some aftermarket stuff here. Are those intake manifold chrome plated? It looks like both those and the valve covers are, which would not be stock.

A big deal in Dynon marketing (Robert Hamilton) is my former partner in N40XE. Maybe you could shame him into moving this along

I can second Florence. Nice sleepy town. No instrument approach, though.

I was watching "The Last Samurai" yesterday, in which the leader of the Samurai has said they refuse to lower themselves to use firearms.Into my head popped a picture of an off screen rant by Ken Watanabe saying "With a sword you never run out of ammunition!"
