Had my spark plugs changed at 70,000 klm.

Mechanic charged me 1 hours labour for the job..

I didn't think that was excessive?

Bigmike...

Not at all Big Mike. I hr is very reasonable. It probably saved you a lot of cursing and frustration so would be great value for anyone not wanting to DIY it.

My car has over 120K and still going on original plugs. No issues thus far. I'll pop one out this weekend and take a look and see how well it's fairing. I'll post up some pics when I do.

Cheers guys :thumbsup:

I had mine replaced at 105k, my mechanic said they usually do 150k km easy. At 105k km the plugs looked  nearly new.

My 2008 Aurion, approaching 200k on the odo, is still on the plugs swapped in at the 90k service, no issues. Check out toyotanation forum, in the US they're apparently serviced at 120k miles which is, what, 200k kms?

That's awesome ! Not sure what brand they are from factory, but it's testament to quality.

If you've been charged 1hr labour for plugs, then I'd be considering the possibility the rears havnt been done. 

On the 40series at least, they are done at 150k. I just did the rears on mine, and was time consuming but not difficult

I doubt it. But anything is possible. I'd ask to see all my old plugs to check their condition. At least you will know all were replaced. 

How anyone could take money to replace all the plugs and only do the front would be a low act and if such a person has been found doing this, then they need to outed.

As per page EG-97 of this pdf of the 2GR-FE,

" Long-reach type spark plugs are used. This type of spark plugs allow the area of the cylinder head toreceive the spark plugs to be made thick. Thus, the water jacket can be extended near the combustionchamber, which contributes to cooling performance.Iridium-tipped spark plugs are used to achieve a 120,000 miles (193,000 km) maintenance interval. Bymaking the center electrode of iridium, the superior ignition performance as platinum-tipped spark plugsis achieved and durability has been increased."

Given this info, it would then be prudent to keep your original plugs,if you decided to change them prematurely that it.  I hope you guys who replaced them at 70 or 80K still have them as they are still good for another 100K it seems. These Iridium tipped plugs are super high quality and the degree of difficulty in having to do them either once or never during your ownership makes for a good arguement against doing them too early according to PDF.

On my 2008 I have Denso FK20HR11 and on my wife's 2013 NGK DILFR6D11, these go on sale at Repco every so often. The Denso ones are from Toyota.
