which spark plugs work for your 3sgte? Options

[toyotacrazy]

Im about to do a tune up and Ive read some forum discussion about "ngk copper" plugs. Are these the best to use to help reduce chance of knock? If so where do you get them? Thanks

If you misfire, drop .002" until you stop misfiring.

In my opinion Iridium plugs are not worth it at all..I have only ever had problems running iridium plugs in the 3sgte engines...much better to go for the cheaper platinum plugs or normal copper core plugs which have never let me down yet. NGK are a good make along with Champion and Bosch...avoid Denso plugs if you can...the quality of build is not very good.

Wow
You have it a$$ backwards man...
Champion is pure junk.
Bosch, while not junk, aren't very good in Toyotas.
Densos are excellent.
IMO NGK are best though.

This comes from working as a Toyota tech.

That comes from owning and running a real GT4 for over 3 years now and trying all those plugs out....but what ever, have it your own way, I find that most advice I give here is either ignored or contradicted anyway so why should this be any different...........I wouldnt take my car anywhere near a Toyota garage as they dont know there arse from their elbows. The first and last time I took my car to a toyota garage they didnt even know what it was, and refused to work on it as it was to complicated for them, most of the advice you give is top notch but saying you work as a toyota tech is no boast at all.

It might work fine on your car.
From my personal experience [and the master techs at work, starting from when they used to change plugs more often] those plugs can and will cause problems. Not in every single engine they are in, but definitely in quite a few.
We used to have a pile of those type of plugs that had been replaced with Denso [we normally use those because they're OEM] or NGK in some instances, because of poor running issues.

Just like any other shop, it depends where you go.
Just because the dealer you went to had idiots working there in no way means all dealerships are full of idiots.
Assuming that is ridiculous and stupid.....

Mentioning I work as a Toyota tech was in no way a boast. It's not exactly a big deal. There are plenty of techs that do.
The reason I mentioned it was because I have seen problems with those plugs in Toyotas. Not just one car, or just one model or engine, but over the full spectrum of Toyotas.
Which I think gives me the right to contradict what you said.
