That box that has been in the back of the club hangar and one of the members said "Allen could see if you can sell it?" - I have some other stuff I'll post separately.

I'm not sure the Aircraft Spruce prices are accurate but if they are its worth more but I'm going to say the four items for $1000 or make me an offer. They are all new in box. I did remove one to take a picture.

Allen, you can try the Vans RV forum too. Pretty sure that stuff is experimental and most those guys are running Lyc O-360s. GLWTS

Thanks. I had assumed we bought it for our Archer before my time

It's installed on my certified C24R Sierra and Installed back in 2001. Not used much anymore, think there were complexities and costs that got in the way, with not much reduction in fuel burn. Ill PM you.
