Spark Plug Socket Size

[Strider]

Anybody can help me with this. What is the size of socket wrench for the spark plug? Thanks a lot

I think it's the smaller size. there are only 2 sizes as far as I know...

I'm actually browsing through Sealey catalog. My company want to buy some tools and am thinking to chip in. I come accross 3 different size 10mm, 12mm and 14mm. I'm confuse now.

if i am not mistaken it should be the 13/16 inch socket. which is around 20mm

Frankly speaking, I never use the spark plug socket wrench inside the tools box at the boot. So, this morning I measure the internal part of the socket with vernier caliper and it measure 16mm on the flat side. Does this mean it is 16mm?

funny thing this....

you could buy at any hardware store... they have only 1 size AFAIK. i bought one a few days ago to service Skar's car. we tried taking out the spark plugs but instead the wrench broke :blush:

moral of story.... send to workshop to change spak plugs. others can do your self
