Spark Plugs Due at 30k?

It was. Just for parts.

I'm not seeing a set of 6 on eBay. The price on eBay for each is only slightly better.

 

They appear to be Denso Iridium Long Life plugs, part # FK20HBR8.

According to the stealership, for the 3.5L V-6, Toyota part #: 90919-01263

 

Do you need to replace any gaskets, or was it as simple as remove anything in the way and reassemble?

 

Should you probably not this first time it was an orange o-ring type gasket with some form of oily lube on it. The gasket never popped out of the upper intake, I left it at bay. On re-assemble I stuck with a cross pattern and torqued to what i thought was right. It was a fairly simple process the driver rear cyliders have a few hoses that need to be pushed out of the way. Very last cylinder has a insulation cover that needs to come off. Pass side is the easiest, but pull the intake first and work towards the passenger side is what I learned from doing this. The plugs were denso and I installed denso plugs.
Hope this helps anyone trying to do this
Mentioned insulation cover

 

I didn't read anything. I just looked at it and took it apart. Pretty easy but I do this for a living

 

Well cmon now...no need to rub it in haha!

 

Thanks for the spec.

 

Awhile ago I called dealer it inquirer about changing my plugs at 30K miles and was told plugs are good for 100K miles.
Now I'm not sure if I should change my plugs sooner? My truck still runs like a champ!

 

most new vehicles are maintenance free for the first 100k, I believe it is just the dealers getting more money..

 

Look in the maintenance book in the glove compartment, it says 60k for the V6.

 

No it's not--its just like every other service.

 

I believe the 100k spark plug change is for the 4 Cyl Tacoma

 

From Wikipedia:

"...Under the hood Toyota offers a 2.7 Liter I4 paired with a 6-speed automatic transmission or the existing 5-speed manual and a 3.5-liter V6 which runs Toyota's D-4S system switching from port to direct injection based on driving conditions and runs on the Atkinson cycle using VVT-iW variable valve timing. The 3.5-liter V6 delivers 278 hp and 265 lb-ft of torque. This engine is offered in both a 6-speed automatic and manual transmissions...."

I am not fully understand about Atkinson cycle, is it possible V6 Tacoma recommended to replace spark plug at 60K due to Atkinson-cycle engine.

 

if it aint broke.........and it runs good with consistently good gas mileage, don’t change them.....

 

Same here lol...you guys do not need to take off the intake manifold, did plugs on two 3rd gens the other day takes about 20 min.

 

Multiple swivels? Only way I can see it being done. I like to take my time on my truck, no flat rate rush on this baby.

 

This is how vehicles become problematic earning them money.
diffs/tcase/manual trans should be done every 30k
Plugs on this truck are good to 100k I won't do them this soon again.
Oil every 5k
Your truck will last a lifetime

 

does anyone know if the end threads of the plugs are prone to carbon buildup on this engine ? In the past on other engines if the plugs were in too long , the carbon on the end thread could destroy the threaded holes in aluminum heads while removing the plugs . Maybe this is why they need to be replaced at 60K ? Also , is anti seize compound still used on the plug threads during assembly ?

 

This is not a ford

 

No, I just use a regular spark plug socket and a long extension. And I agree not rushing is always the better option.
