How To: Spark Plug Change (1 GR-FE)

I just did mine using this guide. 150k miles and my taco is still running like new. Thanks!

One item that made it much easier is that I have a spark plug socket on a hinged swivel, especially on the driver’s side.

Another tip is I used a very thin layer of axle grease (waterproof type I use on my motorcycle) on the rubber boot on the coils. They looked dry. Greasing them up a bit brought them back to life. I let them sit for a few minutes then I wiped off all the excess with a towel and they looked brand new.

 

Thanks for the guide!

I am at 35k doing the first change of spark plugs, should I get the original spark plugs or which ones are recommended? Thx

 

Another option for you is the

$10 NGK LFR6C11 NGK (7787) LFR6C-11 V-Power Spark Plug, Pack of 1

NGK LFR6C11. The stock truck comes with NGK on one side and Denso on the other. I tried Denso the last 30k miles so I went with NGK this time around. I can't tell the difference.

 

Thanks to both of you, also if I buy them from the dealer, do they come pre-gapped? Or I have to do that aswell.

 

Ok Great thx, I will go and pick some up today at the dealer

 

Hi Chris, why 2 size ratchet drives, (3/8" and 1/4")?

 

Just use 3/8.

 

Thanks

 

Chris, How's the Rubicon? I rented a modified one in Moab a few years ago. It was unstoppable on the rocks.

 

Great write up Chris, Truck was running like shit, changed the plugs today, runs great now. took me an hour, wasn't bad. Had 80000, and that was the 1st plug change.
Thanks again

 

Did mine today at 29,299 miles. 2nd time I've used the write up ( 2 different tacomas).

The instructions are the best! Thanks so much for your effort to put these instructions up. I didn't have to the store, already got the favourite beverage.

Did mine today. Chris, thank you for the great write up! That front drivers side plug is a PITA.

I bought my truck at 130K. It has 133K now. The Denso plugs had gaps ranging from .070-.075 and the NGK plugs had gaps from .075-.080. Could they be the original plugs? I would think that if they were ever done, it would've been Denso's all around.

 

Sub'd
For future use.

 

I did plugs on my Tacoma few weeks ago. NKG plugs were on one side and denso on other side. Tacoma has only 41k miles btw. I got truck from the first owner and in all maintenance records I couldn't find spark plugs replacement, even they are due every 30k miles.
My NKG plus were with about 0.50 gap and Denso plugs were with about 0.44 gap. If you find NKG plugs on your truck it is possible that they are original. Anyway I dont see any difference in how my truck run and gas usage since I replaced spark plugs.

 

Yeah, I think they're original. They don't look too bad for having 133K on them.
