Best Long Lasting Spark Plugs?

[Sh!tyThePirate]

I've been using NGK Coppers for all of my Fjs life (36k) switched 'em out...two, three times? Anyway, I've decided I want something more long term...like 30k-60k lasting ability, with the NGK Coppers I feel like I have to replace them every 7-10k to maintain optimum performance, but boy does the FJ pur when you put them in.

Can anyone recommend long-term spark plugs? Which type? Do you need to put anti-seize on them? I've been putting Anti-Seize on the NGK's but since I take them out so early, I figure it isn't really needed.

Sorry, can't help - I just use regular old Denso plugs, I'm on my 3rd new set.

I always put a dab on every spark plug; ensures that they will come back out no matter what. Especially important when you've got steel spark plug threads in an aluminum head.

I would recommend E3 spark plugs. Although there is a lot of speculation about the performance value of these plugs, they have a very long lifespan. I just recently put a set of E3 in my FJ and although I wasnt looking for major performance I was hoping for something reliable. My friends who have been using E3 have put over 50,000 miles on a single set and have had no problems, inspection of the plugs showed no changes from the first time they put them in the car. I hope to get the same longevity.
Would recommend anti-seize as well.

I put in E3 plugs about 1,000 miles ago. They are supposed to last a long time, but only time will tell.

EDIT: they are not very expensive compared to other plugs that will fit the FJ. They can easily be found for $5.99 each.

What ever toyota put in it from factory. 80,000 miles on my 07 still runs like new. never changed plugs.

NGK iridiums have lasted almost 70k in my FJ.
I have a major service coming up and will probably pull them at least to check the gap, perhaps replace them..
These were the most expensive plugs I ever bought, $12 each.

I just swapped out my stock plugs for the Champion Double Platinum. At 35K i had a sudden drop in performance and mileage, so figured that the plugs would be a good starting point.

I am watching them real close to see how performance and my mileage do with them in.

I have been extremely happy with the factory Denso's and a little anti-seize. After 30K they were only worn .001" off original spec and looked like they could go another 2 rounds before changing.

I'll check into those E3's and NGK ir..(can never spell the last part). I always find it hard to put on a "little" anti-sieze, but I do guess if you just coat the bottom of the threads, as you screw it in it will coat the rest...

Plugs are pretty easy to change and cheap enough to not let it be a change deterrant. My last set of factory plugs cost~$20. That's cheaper then oil.
