John,

On our 320 we used the Vans RV6 airbox. This uses a large K&N automotive filter. It has a well thought out and functional carb heat feature. The downside is that it is big. Some surgery will be required on the bottom of the cowling to make it fit.

What's everybody using to filter the air intake to the carb, if
anything? At the moment, I have no filter at all. Any suggestions? --John
