Increased port wall thickness - eliminates problems with warping and cracking.

Computer-generated head fin configuration - deliver more uniform heat transfer and fewer "hot" spots.

Manufactured from the most advanced alloys available - exceed industry standard for strength and porosity.

Note: Item does not include piston pin or rocker arms.

Installed on a Cessna 150 with the 0-200 engine. So far no problems with a little over 3 hours flight time on new cylinder.

We are in the process of restoring a 1962 Cessna 172C. The O300 power plant runs well but is getting tired. We used Superior Millenium cylinders for the top overhaul. The quality and workmanship is exceptional. Very pleased with the purchase.
