Fits 124 201 126 Chassis with M103 engine only, including 190E 260E 300E 300TE 300CE 300SE and 300SEL . These are the current plugs Kent recommends for this 6 cylinder gas engine. Others have tried Platnium and other "high tech" spark plugs only to find out they don't perform as well over the long haul (especially if your engine is burning any oil at all). We have seen a number of no start and poorly running 103 engines, simply due to bad spark plugs. Make sure your plugs are one of the first things you check if you are having hard starting or idle issues with your car or your engine just quits while driving.
Product Details
The original plugs are no longer made. Bosch is not currently manufacturing any spark plug with similar characteristics to the originals. So Kent feels these NGK plugs are now your best choice. YOU WILL RECEIVE A FULL SET OF 6 NEW PLUGS. Kent has put together a special installation kit to help you install your new plugs. Don't just "throw" the new ones in and push on the ignition wires or you just may end up having problems. See this kit in the related products listed below to learn more:
