Spotlight: ECI Cylinders and Engine Parts
Like many aviation pioneers, ECi cylinders and parts (more formally known as Engine Components International) got its start equipping American troops across the globe. Europe was engulfed in flames when the company, then called the Pennington Channelcromium Co., was founded in 1943. ECi soon supported the Army, the Navy, and the Air Force.
The key innovation was the company’s cylinder barrels, which featured advanced corrosion and wear properties thanks to chromium plating — state-of-the-art technology at the time.
Today, ECi has grown into the largest private aviation piston engine company in the world, and a leading supporter of independent rebuilders. From its headquarters in San Antonio, the company has moved on to newer, better plating methods. It has also pioneered a high-level repair process for major piston engine components, including camshafts, connecting rods, valves, seats, springs, crankcases, and sumps. In fact, ECi is one of the few aviation companies compliant with both ISO 9001:2000 and AS9100 international aerospace standards — rigorous quality management benchmarks that give customers peace of mind and confidence in ECi’s products.
In other words, ECi’s quality has proven to be high enough for mission-critical use by all three branches of the American military, yet consistent enough for unwavering satisfaction from general aviation customers.
Here at Air Power, we’re proud to offer a diverse range of ECi certified replacement parts for both Continental engines and Lycoming engines, including piston rings and gears. And our ECi nickel barrel cylinder kits are crafted from a cutting-edge nickel-carbide process, which gives it extraordinary ability to resist corrosion.
