Toyota Century servicing.

[21st Century Man]

Can anyone recommend a good JDM specialist that wouldn't be concerned or worried about doing a spark plug change on a V12 Century? Has maybe even done it before?

It's quite a job as pretty much the entire induction system has to come off with the top of the engine stripped down, and there are various pipes and gaskets to replace upon reassembly too. I'm quite confident that my usual garage would be OK with it, but it would be great if there was someone with actual experience, unlikely though that may be!

Thanks.
