Have removed my lambda sensor and need to temporarily plug the hole , anyone got a plug for it ?

what is the thread?

am I right in thinking that an old 18mm spark plug will fit?

Yup. It's the same thread...
Alternatively, you can buy plugs from various places including STM...
Ebay flog 'em as well. Infact, the listing for Innovate plugs confirms

"...The thread size is 18 mm diameter hole with 1.5 threads/mm pitch...."

"...It is also ideal for Flammer Kit installation as the thread is exactly the same size as a normal Spark Plug...."

Ask at your local exhaust fast fit most new down pipes come with a plug screwed in.

GP racewear sell them, they also sell the weld in adaptors quite cheap.
