For the Experimental Market

The XP-360 Engine is a brand new, “zero-time” four-cylinder 360 cubic inch engine designed to meet the demands of discerning homebuilders and experimental aircraft kit manufacturers. Created with all the advancements Superior is famous for, the XP-360 Engine delivers a level of safety and performance that is well ahead of anything in its class. It may look like the typical Lycoming parallel, large-bore O-360/IO-360, but that’s where any comparison ends.

Superior’s XP-360 Engine includes the latest improvements in component design and manufacturing technology and is created with a blending of FAA-approved engine parts, and other custom enhancements, that are not available on standard Lycoming factory engines.

In addition, Superior Air Parts warranties the XP-360 Engine to be free from defects in materials and workmanship for a full ONE (1) YEAR, with an option to purchase additional coverage to increase the warranty to three (3) years.
