Spark Plug Socket size Suzuki Alto 2010

[mk08]

Hi
I want to change my car's spark plugs. I have bought a socket set which has come with a 21mm spark plug tool as well.
I ordered spark plug and tired the 21mm socket on it last night, but the 21mm seems way bigger.
Does anyone know what size socket do i need to change the spark plugs?

If you have a new plug to hand measure it against a spanner

But most common plug sizes tend to be 26-18 and 21

I don't have the correct size spanner/socket to measure.

Does it not say on the me plug box?


Also what engines is this sombody here is likely to know but the engine as they probably have the same one

My money is on them being 16mm. You should be able to cofirm by putting the spark plug part number into Google or use a ruler to measure across the hex.

Assuming this is your Suzuki Alto 1.0 litre 2010 NGK's partsfinder site says their plug is IKR6G11 which has a 16mm hex so you need a 16mm plug socket.
