Angier,
What I used is just some flexible baffling material between the cowling and the airbox. Remember, 99.9% of the time there is VERY little relative movement between the airframe and engine. The most relative movement occurs at start up and shut down.

I'm currently trying to decide what material is best to use for a flexible connection between the cowl air inlet and my air filter box.
Is CAT duct the best solution or are there other flexible tube/ducting possibilities? 2.25 to 2.5" ID would appear to be a good size.
Thanks in advance.
