4 cyl Camry near 100K miles on original plugs. Time to change?

[andyd]

Runs great, 30 mpg, I'm happy but I have no clue of recommended interval. I s'pose I could google, or even take one out but if I can get a thread going. Should I just get whatever is in there or is there a better plug/ How much at Auto zone, Toyota dlr, etc? TIA

denso/ngk plugs

I have run plugs out to 150,000 miles a couple of times without problems. In other words, there is no hurry. I would buy whatever came in the car from a reputable source. Wait for a good price.

I'm currently over 140K miles on original spark plugs on the Yaris, looking to get them swapped early next year. No problems so far currently. runs like a champ.

We took our 2004 Camry to 209,000 on the original plugs before they began misfiring. We replaced them then with NGK Platinum and they are still going great with almost 300k on the car now. If you do replace get Denso or NGK since it’s a Toyota. Toyota plugs are Denso in a Toyota box for way more than Denso plugs.

Think I would put COP boots on with some silicone grease at the same time. NGK (or Denso) all the way! From a reputable, NON AMAZON (nor eBay) source-RA is usually pretty good, although there is always a chance codes and/or a rebate could make AAP cheaper.

It's like a 30 minute job at a leisurely pace, plus $50 in parts. Heck, I'd do that plug swap just for the entertainment value!

How hard is it to look up the recommended plug change interval in your owner's manual?

If they are the NGK Laser Iridiums then 100k miles is probably just the right time to change them.

You shouldn't wait until a misfire to change them.

Take a look at this plug from my Durango with 106k miles on the plug. It needed to be changed.

I would buy a set of Densos and break out the tools. Cool engine of course.

 

[eljefino]

It's good to get them out, even if you're putting them back in. Don't want them freezing in the head. Mirroring others in saying get plugs from a reputable source.

That must be good American Made cars/trucks????

The 4 cylinders Toyota are easy to change.
FWIW, I would not worry about it at around 100K miles.

Unfortunately, the stealership price on spark plugs is sometimes cheaper than AZ or OR or Napa.

I bought a set for my Lexus, it was cheaper than even RockAuto since it was free shipping from Park Place Lexus Plano.
I paid less than $12 each for Denso Laser Iridium OEM.

NGK Laser Iridium Or Denso Laser Iridium

Toyotas are finicky with plugs…….Stick with NGK or Denso. There should be a little sticker on the left side of the valve cover with what is recommended.

That looks like something on the Titanic.

I think wwillson captured not only the nitty but especially the gritty!
