Spark plug recommendation
Which spark plugs do you recommend me for my 3.2 carrera (1985)?
The owner manual says something about Bosch WR4CC but I think that there must be something newer or better. Thanks |

I'm not sure about newer or better, but I have always had good luck with NGK plugs. For a US-spec 3.2, the correct plug should be a BPR6ES and for a Euro 10.3:1 compression engine, I believe NGK recommends a BPR8ES. I have run BPR6ES, 7ES and 8ES in my 3.2 (with 10.3 compression) and am now using the BPR7ES plugs. For NGK, the higher the number, the "colder" the plug (which is opposite of how Bosch does it IIRC).
You can also check NGK's website for recommended plugs.

The exact match for the Bosch plug in NGK is the BPR6ES, which is what I run.
