560 Ignition Leads

Post by oversize » Thu 22 Nov, 2018 5:35 pm

Who’d think it’d be so hard to find the correct ignition leads?

Beru ZEF566 or
Beru ZEF670???

When I checked the EPC and compared lengths; the 566 set seems the closest. But an internet search revealed the 566 has ceramic adapters (huh??) whereas the 670 does not. More confusing is the 670 is apparently for the US market and 566 is Euro. The Beru website and my local suppliers are no help. I’m using NGK non resistor plugs, so I need leads with suppressors.

Anyone care to enlighten me??

Hello & G'day,

I just looked at the Beru ZEF 566 wireset on a UK website and this set has the proper metal plug connectors..
Further research assures that the connector ends have 1000 Ohm resistance which is consistent with both my US 560 & my German market 500SEC.

For reference: https://www.bestpartstore.co.uk/991771- ... spark-plug

That is the set I would be purchasing.

Good luck,
