    Which airforms baffle set for pa-12 Kenmore 150?

    Hoping for someone who has been before. I called airorms and they were not sure which set I need. They have a non-PMA "pa-12 150" kit or they have the pa-18 PMA'd kit.

    The Kenmore STC calls for PA-18 baffles.

    Here's the catch. They'll take the PA-18 set back if I order them and they don't fit. But they WON"T take the pa-12 kit back if I order it first and it doesn't fit.

    Is there anyone that has installed one of their kits on a Kenmore 150?

    I used the PA12-150 non-certified kit. Had the owner send an email to build to his specs per owner produced parts. PA18 baffles will interfere with the top cowl rails. Pictures of the baffles installed on a Kenmore STC'd 320 powered PA12 and PDFs I got from Airforms with pictures of the individual baffles.

    Steve, with the baffles so close to the cowl channels is there any issue with those interacting/fretting?

    They still look good, no rubbing. Here is a photo album with the above pictures from 2016 and some from several years later. https://photos.app.goo.gl/BKrmgPg91e5gx7cK7

    Engine Baffles on a modified 12 is like every other PA12 part: cut and fit, cut and fit, cut and ..... wish you bought a plane that didn’t need so much personalized fabrication.

    You should expect to do some tweaking in the engine compartment to get the airflow/cooling just right for each cylinder. It is one area where one size never fits all.

    No different than an 18, depends on who rebuilt it and the effort they put into not butchering it so that anything and everything has to be custom fabricated.
