What period (kms) should you change spark plugs?

[daves8]

My 2015 L77 calais now is approaching 110kms.

I am researching getting trans fluid and filter changed, and was wondering when the plugs should be done?

is it on a as needed basis, or is it recommended at a certain km?

cheers

Your service booklet will tell you.. but definitely good idea to change at that milage...

For Ls3 the interval is 150 000km but some owners are finding their plugs stuffed at as low as 50 000km.

Pull one out and have a look if in doubt but if i was you I would change them now...

i always do them around 100,000km which is usually around 5 to 6 years.

Yes, was planning on doing them at the 115,000 service in addition to trans.

Personally, I’d be doing transmission fluid every 40-50k kms (particularly if towing).

You might consider diff fluid as well. It’s not in your service booklet but it breaks down just as much as every other fluid in the car.

People who do it report how it shimmers with metallic particles upon changing

Plug change is in the books.
Can’t remember the page number so best to look.
