Hey Guys,

I need a new set of plugs wires for my 89 S420. It's got a miss and the end of the plug wire that fits on the spark plug itself has started jumping off. It's not tight any more.

I just checked the parts online here at MercedesShop.com, but there are three brands of wires, Bosch, PVL and Beru. All I expect is original part quality in replacement parts.

IS the Bosch original? Whats better about the PVL? And, whats even better in the Beru brand? The price gets higher, but the wires look the same.

Thanks in advance!

Bishop
