Overview

Uniform hardness all the way through the steel barrel walls which allows the barrel to provide even wear while withstanding extreme cylinder temperatures and pressures.

Exhaust and intake ports are volumetrically matched to maximum output and performance.

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.

+ Included with stud assembly.

Reviews

I did this once for the other cylinder, give me about 1000 hours on the engine and Ill tell you how good they are. They have a good recommendation from my mechanic and that is enough for me. The last cylinders we ECi cemachrome and they lasted 1600 hours and were still holding up with 65-75/80 psi. All cylinders other than Contintenal are seem to make it to TBO. Now that ECi has been bought by the same Chinese people who own Continental Im hoping they will stop making there own cylinders and use the ECi ones.

Im replacing all the cylinders on our O-470R Continental Engine off our 1963 Cessna 182 while we rebuild the engine. Superior has had a very good recommendation, but ask me for a review in 8-10 years when it has over 1000 hours on them, I hope they are as good as the ECi chrome ones that were on the engine last time that got 1600 hours in 28 years.
