SPARK PLUG SERVICE

what’s up fellas
my 07’ black mamba is at 127k miles and i’m just now going to replace the original spark plugs.

i purchased NGK laser iridium replacements.

my question is, what else is recommended to service at this time? or any other recommendations for service at 127k miles ?

 

With that mileage I would change coil packs too. And use anti seize on the plugs.

change plugs every 50k
Coils every 100k

 

thanks for the help

i am buying the parts from my local Autozone and i have 2 options for the Coil packs… they have the duralast with lifetime warranty and Denso with a 1yr warranty

which do you recommend ?

 

I wouldn't replace the coil packs til you need to replace the coil packs. To each their own though, I guess. Not a common failure and you’ll know when you have it.

I’ve replaced my plugs twice, each at 100k’ish (210k miles now). Original coils still truckin’.

There isn’t much else there to get pro-active on, if you’re simply doing plugs.

 

Anndd dont use anti-seize on the plugs either. (Its not 1971)

Almost every plug manufacturer(like NGK in your case or factory Denso’s)uses a coating on the threads to prevent seizing.

If you gotta scratch that itch, make sure you apply a little bit near the center threads and dont torque too much. Or the threads in the head are coming out with the plug.

 

Yep. To each their own. Having built literally hundreds of tundras, I base my advice on real world experience. Your truck would perform better if you’d look at the advice I’m giving you.

Coil packs sometimes ‘just go out’. But usually that’s not the case, usually they just don’t work as well. The most common failure that I see is a small, random voltage leak. You can actually tell by looking at your fuel trims.

to tell a guy ‘you’d know when you have it’ is extremely vague, random, and is simply bad advice. They’re inexpensive enough to change as a matter of fact. As a matter of fact I’ll be bold and say this, ‘There should be a change interval specified in the owners manual’.

 

these are aluminum heads. You need anti seize no matter what year it is. It stops the plugs from sticking into the head. And it lubricates the threads for a more accurate torque reading. Also, look up the torque value for yourself. I’ve always used 18ft lb. moral of the story, use an actual torque wrench. Don’t just guess.

 

I just looked up Ignition Coil Packs on the Sparks Toyota website.

Are they really $85 each?

Do you need to get eight of them?

That might be out of my price range.

 

What I did:
Buy an 8 pack from Autozone. Bring an extra couple of your old stock as back up thst ll I hate to admit to using Autozone parts, especially electrical. But they worked better than my old factory coils with 200k mikes on them.

 

Rockauto has Denso coils for a little over $50 each. Another option if you are thinking of going that route.

 

Definitely the route I would’ve taken if I had the tine to wait. With the OP doing this project at his convenience this would be the best choice.

 

GOOD MORNING,
does anyone know torque specs for the spark plugs and coil packs?

i finally have time to do the job
and my oil change while im at it

LMK thanks

 

I never torque the coil packs. No need to. Dirty Deeds says 18 ftlbs on plugs. Seems like a good number. Tacoma 4.0s are 15.
