Engine Plugs

[jimhof]

Is there a way to use different plugs to get better than 30K out of them on my 2006 V6? For a newer car, that is extremely low usage.

Thx,

Jim

Go with Iridiums. NGK and Denso are the top dogs around here. I personally went with NGK Iriduims and they will last about 100k miles or more.

So you can get 100k out of them. Didn't know that, or haven't searched either. I guess you can teach an old dog a thing or 2.

Yep ther's a cpl old posts about them NJShadow93 included , but some think 30k are still better . I di d the iridiums so far so good , did break 1 & for 1 GD plug ran all over town ea. store said no the OTHER store after they made the call .

I usually use the oem Denso, they do seem to burn hotter, but, peter out before the 30k.
I can tell by the fuel mileage before next change.

Plugs, plugs and more plugs

Thanks a lot for all the advise. I would rather get under the hood once instead of three times and now I can.

I run the coppers every 30k. Copper will have the best spark intensity, but will wear the fastest. Probably doesn't matter because our engines are cop, good solid ignition system.

I had a Toyota 1MZ-FE V6 that ran for 250,000 miles on what I determined to likely be the original set of Denso Iridium plugs. I bought the car with 144k miles on it, so even if they had been replaced, which is possible, they lasted over 100k.

My idle got really rough and I replaced them at 250k. it felt like a brand new engine after the new plugs were in. But still, I was amazed that what appeared to be the original plugs lasted so long. I remember the days when plugs were recommended to be replaced at 15,000 or so.

The original Denso Iridium plugs in mine all looked pretty good when I took them out at 104,500. Replaced with NGK Iridium and a little anti-seize on the threads and dielectric grease on the coil pack connections. I don't plan on touching them again until 200K.

^^ I think he missed the conversarion.

Go with the Denso or NGK Iridiums. I put them in mine after pulling the original plugs at 100k. Originals aren't iridiums by the way, just a copper NGK on one bank and Denso on the other bank

I use NGK in any Japanese engine - personal choice

The Iridium are rated to last 50K, Platinum are 100K.

Personally, I wouldn't go more than 50K on any set of plugs. You want the engine to run optimally and for the 45 min and the $40 its worth it.

I second that! The other issue with leaving plugs in an aluminum head for an extended time is, the greater possibility of wiping out the threads from carbon build-up or the plug seizing in place.
