Changing spark plugs in 2005 Tundra V8...advice needed

[kenmac]

Was that when the Tooth Fairy took your last $1.00?!

Here's the link which shows which plug goes the 80-100K:

Yep, I guess I should have looked it up instead of taking someone's word. I've only got about 42 K on it so, I'll wait a few more B-4 changing them out


How Long Will My Iridium Spark Plugs Last?

All 3 of my Toyotas have Iridium plugs, and I believe all of them call for changing them at 100K mi.

My MR2 Spyder is past 90K mi now, and the original plugs still look great, plus the gaps are in spec.
Maybe I can go beyond 100K mi.....

I always lube plugs threads before installing, tho I have never heard of a Toyota having a siezed
plug.

I will double-check plug specs when I buy new ones.

The truck has 95,000 on it and OEM iridium plugs in it. I'm putting the same OEM plugs as replacements.

Frankly the plugs last so long I never really thought about changing them until I started to notice a really faint miss-fire when taking off from a stop. I had a good 125k+ miles on them and they were in pretty poor shape.

Any plug replacement should be full precious metal. The cost difference isn't enough to justify the labor in changing them more often. I've had a shop tell me they see the full platinum plugs go 125,000 to 150,000 without a problem. They also recommend changing wiring at that time, but I've had others say that since the wiring is low voltage with the coil on plug design, it doesn't matter. Any experience on that?

Might have been mentioned already..... use a dielectric grease on the boots/seals. Helps seal out moisture, and prevents the boots from fusing on.

Electrical System Maintenance : Permatex

Up here in salt-country, we pretty much need to slather the whole vehicle in this stuff.

(My semi-depressed way of saying..... that stuff is good to use on all sorts of connectors).

1. Cold engine
2. Original equipment plugs
3. Dialectic grease on boots
4. Torque right
5. No antiseize
6. Be glad, very glad you're not doing this on a say, '02-'08 or so F150! I just did my '02. Never again.

I hear dealers charge $500 for a plug change on those Ford V8s, and breaking them off is very very common.
How user-mean can you get?

Another reason to be happy with changing plugs on a Toyota Tundra.....

I'm confused about antiseize since some say yes and some say no.
