MERCEDES BENZ IGNITION COIL BOSCH BLACK 0221119021 OEM 1955

Description: MERCEDES BENZ BOSCH BLACK COIL WITH 0.9 OHMS BALLAST RESISTOR INCLUDED A PERFECT OEM COIL FOR MERCEDES BENZ IGNITION The Mercedes Benz basically utilize two types of ignition coil during production from 1955 to 1981 , up to mid 1969 the factory installed coil was the Bosch part# 0221119021 so called the "black coil " after mid 1969 they introduce the Transistorized Ignition which utilize a module to enhance the system , the coil for those models was Bosch part# 0221122001 also called "the blue coil" Technical Note: On cars equipped with a non -transistorized ignition or a conventional ignition the installation of the Black Coil improves considerably the ignition spark however the use of the 0.9 ohms ballast resistor is a must since the points are subject to a arcing effect , the current flow between them is high , which can cause pitting or damage on the surfaces, a condenser as part of those ignition system also helps to reduce arcing , the resistor also decrease the voltage input on the primary windings of the coil preventing overheat and possible damage to it. On models equipped with transistor module the arcing is drastically reduces since less than a ampere flows through the points , however the resistor should be installed to protect the black coil and improve its longevity , the blue coil originally installed on those models has a distinct construction, the thickness and ratio of the coil windings are designed for a discharge of the transistor module , the installation of the black coil can be done , however it is possible that the life time durability of the black coil might be reduced. NOTE: The Bosch black coil offered is no longer Made in Germany , a original decal has been installed to give a genuine factory appearance .
