NGK 54240 spark plug wire set for the 1986-1993 Mercedes-Benz 300E 6-cylinder 3.0L, the 1990-1992 300E 6-cylinder 2.6L and other vehicles carries high-voltage current from the ignition system to the spark plugs. Insulation around each wire is meant to keep that current from leaking before it reaches a plug.
- NGK wire built on a tinned copper core
- Silicone outer jacket built to withstand temperatures greater than 250 degrees C, over EPDM or silicone inner insulation
- RFI suppression close to the source, built into the spark plug and distributor connectors and metallic resistor boots
- Spark plug boots glued to the cable with a silicone sealer for a watertight seal
- Stainless steel terminals that hold positive connections through the life of the set
- Cylinder lead identification tags, where possible, to make installation easier
Quick facts
- Part: NGK 54240 spark plug wire set
- Fits: 1986-1993 Mercedes-Benz 300E 6-cylinder 3.0L, the 1990-1992 300E 6-cylinder 2.6L and other vehicles
- Condition: New
A misfire or rough idle can mean the wires are aging, and so can cracked or burned insulation or boots that you can see with the engine off and cool. These signs alone do not prove the wires are at fault, since a worn spark plug is another common source of a misfire.

Frequently Asked Questions
Does this NGK wire set fit the 1987-1993 Mercedes-Benz 190E 6-cylinder 2.6L?
Yes. NGK 54240 fits the 1987-1993 Mercedes-Benz 190E 6-cylinder 2.6L, and that car takes one set.
How many wires come with these NGK plug wires?
NGK 54240 is a set of six wires, and the coil lead is one of them.
What are NGK blue spark plug wires such as the 54240 made of, and what heat can they take?
The jacket is silicone, built to withstand temperatures greater than 250 degrees C. Inside it, the insulation is EPDM or silicone for dielectric strength.
What signs can mean a set of spark plug wires is wearing out?
A misfire or hard starting can go with aging wires. Cracks or burn marks on the insulation, seen with the engine off and cool, are another sign; a shop can test the wires.
Is NGK 54240 the same set as RC-EUC041?
Yes. NGK lists this wire set under both 54240 and RC-EUC041, so either number finds the same part.
