BMW has had an ongoing problem with spark degradation through the direct ignition system. Especially a problem operating at the extreme heat conditions under the hood.BMW assisted re-engineering of the coil by Eldor. This is the current solution. Along other things like good fit and finish. S55 coils are a great upgrade to n54/n55 coils, and one of the best coils on the market! For stock vehicles, to any power level needed! These will come in Original Eldor Packaging, unlike anywhere else on the market, to assure you're getting Genuine ELDOR Ignition coil. 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. In 1996, with Eldor’s traditional business development in full swing, Pasquale Forte sensed that traditional television sets would become obsolete within ten years. He decided to invest massively in a different sector, Automotive. Three years on, in 1999, another flash of intuition and a new battery division, in a sector of great long-term potential that extends to current hybrid-electric technology. In 2002, Eldor is the world leader in high tension transformer technology. When Eldor was at the top of its game in Consumer Electronics, Pasquale Forte understood that - to ensure the company’s long term sustainability - he had to change course and point the entire organisation in a totally different direction, the Automotive market. This was a new beginning for Eldor. 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.
