Gentlemen,

I am almost ready to start the engine on my IV-P. A good friend in Colorado Springs gave me a set of K&N filters several years ago to use when the cowling was not in place. Unfortunately, I loaned them out and they did not come back home—and I am not sure who I loaned them to… Bottom line: Could one of you tell me the K&N filter size/type that clamps directly to the turbo inlets?

Many thanks in advance,

Bob Pastusek
