Eldor manufactured coil number 12138657273
Your BMW’s direct ignition coil provides the power in order for your spark plug to “spark”. If your BMW is suffering from a misfire issue it is likely due to a worn ignition coil or bad spark plug. One way to test for a bad ignition coil is to swap the ignition coils and see if the misfire follows the misfire.
We also recommend using dielectric grease when installing new ignition coils. It will protect the spark plug boot and create a water/dust tight seal. Great for added ignition performance.
Note: Eldor coils do not come in Eldor branded packaging as Eldor does not have an aftermarket sales division. This coil will come in a white box or box with BBT Technologies branded on it. The part number on top of the coil in both cases will read “R3516S00100” with a production date/time stamp underneath.
Direct Ignition Coil
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.
Direct Ignition Coil Failure Symptoms
- Reduced fuel efficiency
- Reduced power output
- Misfires
About Eldor
Eldor Corporation was founded by Pasquale Forte in a garage in the small centre of Orsenigo, in Brianza area, not far from the lakes in Northern Italy. The company was specialized in consumer electronics, developing high tension transformers for radio and television sets. In the late 1980s, Eldor opened up to the world: it started to export products and opened sales branches in USA, Hong Kong and UK. In 1991, taking another bold step for the time, especially for a medium-sized company, Eldor set up its first international operations, opening a factory in Turkey, and introduced the same automated production lines that had proved to be so successful in Italy.
Ignition systems production gradually took off, and Eldor devoted itself to innovative work on electronic control units. With its first product, using patented technology for analysing ionising current, Eldor gained the “Ferrari Technology Award” as Ferrari’s best technological partner. Eldor joined a number of European research projects and, in 2009, was the first European company in the motor vehicle sector to put a full-hybrid scooter on the road. In 2009, Eldor won the “Volkswagen Group Award”, the first Italian company in Italy to receive an award from Volkswagen for the quality of its products.
