Spark Plug Gap

Post by Gduplock »

Can people advise on correct spark plug gap for Bosch WR5DC +15 plugs in my 1968 911L 2.0l.

Most gaps quoted for plugs ar between 12 and 18 thou but for other cars (not Porsches) gaps are quoted up to 25 thou.

Thanks

I don't know if there's any reason why those Bosch plugs would need different gaps but I've always used NGK plugs (usually BP7ES) with ~ 0.028" gap.
