Although no longer available from BMW, we have had a major ignition wire manufacturer reproduce the Evo III ignition wires using the OEM Beru connectors. What sets these apart from the standard wires are the red caps and boots, visible as soon as you open the hood. The Evo III wires were standard on the limited edition Sport Evo in Europe and these are a great detail to a pristine engine compartment.

This item fits the following BMWs:
1988-1991 E30 BMW M3
