Some beginner questions about spark plugs ...

- am I correct that the 2023 Discovery V takes six spark plugs?

- am I correct these should be changed by 60,000 miles?

- is this something someone without auto mechanic experience but eager to learn could do themselves?

- if this is something you can do yourself, are OEM spark okay or should I consider other brands? and what tools would I need?

Thanks!

 

I would go with NGK 93710

You can do it!

 

Thanks for the vote of confidence! I'm going to give it a try!

 

if you can, post pictures of the process for posterity.

 

My contact at LR who is very honest with me told me changing them at 60K wasn't really necessary. That said, I plan to do it at 80K. I would also suggest NGK plugs that match the OEM specs. You should be very careful no dirt gets into the engine after you have removed a plug - I would connect a small tube to a vacuum and suck out around the plug before removing it. You should hand thread the new plug into place (with any extensions you need) to be sure it isn't cross threaded before torquing to the spec. Also check the gap on the new plugs to be sure they are correct. The hardest part of the job will likely be access to the rear plugs but I haven't done mine yet so maybe you will be happily surprised. Please see the attachment.

 

2023 is no longer the AJ126 V6, it's the AJ300 Ingenium motor. Plug replacement guide will be different.

 

And my spark plug instructions pdf will also be different. Sorry
