Cylinders in Lycoming engines usually last quite a long time. My
rebuilder says that he almost never sees a failed Lycoming cylinder
from a 320, 360 or 540. This is true regardless of the brand of
cylinder. I have had excellent results from Lycoming branded cylinders.
Unfortunately, ECI just had a bad mandatory replacement (not covered by
their warranty) on their Lycoming engine cylinders (ouch!).

If it were me, I'd use the same cylinder that the engine has on its
other cylinders. Nothing wrong with Lycoming cylinders. Some of the
coated cylinders are better if you live where its wet and dont fly
often as they are less suceptable to corrosion. I don't think its a
huge issue. Any of the new cylinders are going to be pretty good.
