what size spark plug wrench socket do i need to swap out my plugs on a 1969 1600 beetle engine?

thanks in advance.

big one or small one i believe

Sorry mate, im not 100% but i though it was the bigger one. Can't remember official sizing. Someone is sure to answer with a proficient response

the big one that comes in all cheapo sets - cant remember the size either maybe 21mm or 13/16??

And very flexible arms. Plugs on a bug can be a pain to get to.

use the box spanner that came with the car...

wheel bolts on one end...
spark plugs on the other..

I think its 13/16 plug spanner with a rubber insert to hold the plugs..

use a piece of rubber hose on the plug to install them
that way You can't crossthread them

naturally You tighten them up with a spanner
and You should use Never Seize on the threads

if You don;'t have never seize use Lithium based Moly grease - same grease You do the front end with..
if you have torsion bar front end..

Also keep a magnetic pickup tool handy for when, i mean if you drop the sparkplug into the tinware. It's either 21 or 22mm. Like Adsman said it's the big one in the cheapo sets. You need one with a rubber bit inside that grips the insulator on the spark plug properly. Or a magnetic pickup tool and a lot of patience.

That magnetic pick up tool also comes in handy when trying to install manifold washers and nuts. Saves hours of work ehn trynig to find that 11mm nut down betwwen the tinware and the head or spark plug. Especially the back side behind the manifold

thanks guys - all sorted. 21mm 13/16th's was the way to go...

didn't drop anything into the tinware either - haha.
