Capen" Subject: Re: LycomingEngines-List: Questions from my 'annual' I got the answer to one of my questions - the AEL70485 is the correct part number for the intake tube. Still looking to find out where I can get the bulk material that the 69603 part (rubber connecting tube - 1 3/4"ID x 2 3/16"OD x 1 3/4" long) is cut from. Also still looking to find out if anyone else has experienced their spark plug exterior plating peeling off?! Thanks, Ralph Capen -----Original Message----- >From: "Ralph E.

I have experienced the peeling of the exterior plating on spark plugs. I continued using the plugs with no known effects. It did make me question the overall quality of the plugs...

Capen" Subject: Re: LycomingEngines-List: Questions from my 'annual' Thanks Dale! I flew two hours yesterday after swapping them upper for lower. In a few months / next time I have the cowl off - I'll look at the ones I put down there...they lived in the plenum nicely...but a different brand (Tempest).
