Anybody let the dealer change tne spark plugs

I just changed mine last summer. My dealer wanted just under $200 for the job only to change out six plugs, seems high so i got the parts and changed them myself. it really is easy to do as long as you have the right socket, i got one with the swivel extension. and a basic mechanical know how. just remember to put back any hoses and bolts you remove.

 

My dealer wants 150.00 including tax to change out the plugs, so that would be something like $120.00 in labor and $30.00 in plugs

 

Doubt the plugs cost that much, my dealer here in Houston sells the spark plugs for $2.50 a piece

 

OP, as others have said it's an easy DIY job. There's a great tutorial on here how to do it.

One very important thing to remember: these trucks have aluminum heads that can strip easily. Make sure the engine is completely cooled down before removing/installing plugs.

 

A plug for a weedeater will cost you 4 bucks here

 

good advice

 

If you have any mechanical ability at all, you can change these plugs fairly easily. I changed mine at 30k. I think it took me a couple hours and I didn't even see the thread above where it showed you how to do it. I did my own differentials and transfer case as well. Very easy to do. I have a 2015 4WD SR5 with 53k on it. I will be doing it all again this summer. I cannot see as good as I used to (I am 60) so it takes me a little longer to do stuff. You can do it and once you accomplish that, you will be glad that you did.

 

You're crazy. My truck had the original plugs in it at 168k (when I bought it) and immediately did a bunch of maintenance items, one of which is my plugs. This is what they looked like. Upon replacement, I immediately noticed an improvement.

Ummmmmmm

 

I was going to buy that socket, can you tell me if it sticks out of the spark plug hole? I changed my spark plugs for the first time and I found the socket getting stuck inside. I was going to try to duct tape it next time but was looking at that instead. I have the 2.7 engine, so I don't know if the depth is different than your 4.0.

 

I can't remember if it sticks out of the hole or not, but I do remember that I had no issues with it getting stuck inside. It's also magnetic to hold the spark plug in it, which is nice. Makes putting in new ones a breeze.

 

You've already gone 40K over recommended plug change. Why not go another 5K for spring or summer to roll along?
Pricing will vary region to region. A plug change is a basic maintenance item. I'm sure there are competent auto shops in your area that can do this for you. Use Yelp to help locate them. Many will give you parts options so you can choose OEM plugs if you want.

 

Chris4X4 (I think) did an amazing job at documenting changing the plugs on a 4.0L. When I had my '07 Prerunner, I was able to change out all six plugs in less than 90 minutes following the write-up. Plugs at the local dealer were about $2.50/each. Changed them out at 30K miles and got 20+ MPG on the 2WD. Be sure to anti-seize the threads and lube the boot with dielectric grease. Also, pre-gapped means nothing!

 

Was quoted $444 at local dealership. asked why he said labor, mentioned having to move alot of stuff to access plugs. Pointed out that inexperienced people have been reporting sub 2 hr completion times and he wouldnt budge. Lame. Going to do myself soon.

 

Wow thats almost 3 times the cost of having it done down south, i guess the cost of living in cali is high

 

Doing your own plugs is as easy as an oil change. Just do them yourself.

 

Toyota also says to change the spark plugs at regular intervals, lol. I guess we're all free to pick and choose what we want to believe or ignore.

 

The plan was not to use anti-seize, even though I bought it just in case. I hand tightened the first spark plug and couldn't tell if I was cross threading it, so I went to the anti-seize and it made threading it in a lot easier. Good advise to always check the pre-gapped plugs.

 

Mine were changed once at 30k miles and I'm right at 60k now.

Can anyone recommend the Denso irridiums? Any reviews?

I only drive around 8000 miles a year and it would be nice to put in some irridiums and forget about it for 10 years.

 

I tried iridium plugs and changed them within 100 miles. They do not perform well in the V6.

 

I just past 100K with NGK iridiums (

LFR6AIX-11) in both the Taco and wife's Lexus, same NGK part# for both. Did the wife's plugs last week and will do mine in the coming weeks. Both engines run/ran fine with them. I did have to adjust the gap on both when I pulled them at about 80K. Stuck new same NGKs in the Lexus but have Denso Iridiums (
