Volvo Ignition Coil - STI 31312514

Product Information

Direct ignition coils are located directly over the top of the spark plug. In this ignition setup there is one ignition coil per spark plug and there are no spark plug wires. This ignition setup is often referred to as a coil on plug ignition system.

Coil on plug or direct ignition systems are pretty much used on all modern cars due to packaging, performance, emissions, and maintenance reasons. This ignition system is essentially maintenance free with the exception of spark plug replacements and the occasional coil replacement when compared to a traditional ignition system.

• Reduced fuel efficiency
• Reduced power output

About STI

STI is a division of the Karlyn Industries Corporation. Founded in 1971, Karlyn Industries is a family owned business that was started by Mr. Hans Bierdumpfel. Hans was born and trained in Germany as an Engineer and emigrated to the U.S. in 1949. He held leading Engineering positions with such esteemed companies as Sonotone Corporation, formerly of Elmsford/Cold Springs, N.Y. and Wells Manufacturing, of Northvale N.J. before founding Karlyn Industries 33 years ago. The company started producing the first U.S. made VW Beetle Ball Joints and Tie Rod Ends, in Mount Vernon, N.Y. As a domestic manufacturer of Volkswagen suspension items, Karlyn created a customer base here in the United States that has been loyal for over thirty years. Today, Karlyn Industries has branched out into suspension items for Audi, BMW, Mercedes Benz, Volvo, Saab and Honda. Karlyn Industries is also responsible for a high performance line of spark plug ignition cable sets with a reputation for quality. The biggest difference between Karlyn Industries and other manufacturers is their willingness to use a manual assembly process when it proves to deliver a superior product over automated production.
