Improper looking and fitting ignition wires will detract from the good looks of your engine compartment and could even cause running issues down the road. It is very difficult to find a wire set which is built correct and fits correctly. Find a quality set with solid core wire, six straight connectors at the spark plugs and screw off ends. If you know the correct routing for each wire, remove the ends one at a time and trim the wire to length, after routing it correctly. You can screw the end back on the trimmed wire after you make it the perfect length. If you do not know the correct original routing, simply find a good photo of an original engine (plenty on this website). Don't forget the large diameter plastic sleeve, wire collector, where the wires pass over or under the injection lines near the distributor. With later 280SLs, having the plastic distributor cover, the wires pass under the injection lines. All earlier cars the wires pass over the injection lines.
