Spark plugs for a 2008 taco crew cab?

What are the majority using for spark-plugs?
I have 221,000 miles and I might need to replace original plugs.
Should I also replace the wires?

 

Holy crap, that's a lot of miles on the factory plugs. The change interval is supposed to be 30,000 miles. I just did mine this past weekend using Denso K20HR-U11 for all six. I noticed the Densos seemed to have gapped less than the factory NGKs. I followed this guide.

Can't help you with the wires though.

 

OEM plugs and wires plus having the injectors cleaned but that is just me.

Have you kept up with the recommended service items listed in the manual?

 

I use OEM Densos, there are no wires, you have individual coils.

 

If it's anything like mine a many others. You're going to have to need 3 NGK and 3 Denso plugs if you go OEM. Why they come that way from the factory? I have no idea.

I choose to go with 6 Denso. I forgot what the number was on the plug.
I got the number from my owners manual. The plugs seem to run fine.

 

For the V6 the plugs are like $2-$3 each. Go to a dealer and tell them you want six of them.

Wires - I'd replace if exposed to high/cold temps, humidity, dust, etc much over the 220K miles

Post pics of the original plugs....

 

I will try!

 

OEM denso.

you DO NOT need 3 denso and 3 NGK!

 

I understand that. I quoted the guy before me that said "Go OEM"
What I was trying to state is that Toyota went OEM with 2 DIFFERENT plugs in a lot of the 4.0 engines for no known apparent reason?


Further more, I was also letting the OP know not to be concerned if he finds
2 different plugs in his truck.

Choose an NGK or Denso in a quantity of 6 and all will be fine.

 

While we are at it, NGK says NOT to use anti seize on their plated plugs.
That is if you choose NGK over the Denso.

dang mine replaced at 30K with originals.

 

I would like to see some pictures of new vs 30 k plugs or 40-50 k for some of you that go to that.
I can not see why they would use the different plugs per side, if you have the dealer do it they do not, and also other service centers call for a different brand.....

Wonder if a better plug would help power and MPG?
Anyone played with some of the others or plugs that will go 100k

 

Supercharged calls for 100K

 

Replacement with Toyota's plugs went well!
All bolts backed off nicely, coils and it's wire harness separated easily!
Plugs I just took my time and they weren't to bad to remove.
I'm glad I have a long extension!
So @ 221,500 miles this is what the worst looked like, opposite the new ones!

 

Gap looks about 2x nominal but the ceramic looks normal...
Check your milage...of course you'll probably throw a code now when the ECM says "WTF is this shit man?"
