Recommended spark plug for 2007 TL
 

Hi, what is the recommended spark plugs for 2007 TL after 80,000 miles and where to get them? Thanks

None. You still have another 25K miles to go...

Do you not have an owner's manual?

NGK Iridium 6994

I 2nd nfnsquared. Replaced mine at about 112000. Could have probably gone another 10000 w/o issue.

Spark plug conditions after 83k miles
 

Hi. Here are my spark plugs after 83k miles. I replaced them all.
Based on these pictures any concerns or what is the conditions of the engine?

Might just be the angle, but the gap looks too wide.

Other than that, they look fine. You pulled them way too early....

I know but I replaced them while I have time and tools. It is cheap insurance, 6 NGK plugs for $45 from Amazon

plugs looking good to me and your engine is working like it should be.

Insurance? Insurance against what?

Your engine is in awesome condition. Your plugs are showing that they should have been replaced earlier... you save on gas and detonation which there are some little signs on the tips.
Do replace them every 30k miles for you and your engine.

What?? Where do you get that from?? :rofl:

Sorry, pretty much everything you wrote is incorrect; I don't know where you're getting your information from but tell him/her/it they're full of crap.

Very normal. Threads clean and dry, no oil I see. Not overly dark. No significant deposits. Normal amount of wear and no damage. Slight brown color is normal. Plugs weren't overheated, no ash deposits. The ceramic white area doesn't have too much discoloration so they aren't too old (obviously we know this because you know the miles too). Normal. Do a compression test and/or leakdown test and you will have a very good idea of the engines life and condition. Get a valve adjustment and make sure maintenance is up to date if you want to ensure longevity.

The plugs look good.

:chuckle: Cmon, tell us your real feelings on the matter. Stop beating around the bush.

Thanks everyone!
