Spark Plug recommendation

I take my plugs out every 100K miles and if they need to be cleaned or replaced I do what is necessary. I don't automatically throw away perfectly good plugs.

The factory plugs after 74,000 km

 

My local mechanic suggested the NGK Ruthenium HX…I may go with those.

 

Sounds like a fantastic plan to spend your $.

 

I installed the same Ruthenium HX plugs, no problems so far

 

Ruthenium or Iridium, you can't go wrong I'll probably go with Ruthenium NGK's next time

Good to know. Maybe I'll give these a try next time I swap out my plugs

 

Been running rutheniums for about 5kmiles now, no problems to report related to spark. Worth it just for the peace of mind ya know?

 

I would like to change the plugs myself as I used to on my vehicles back in the 80’s…of course it was so simple then with accessibility of them. I’ve watched a few YouTube videos on the Tacoma but I’m still a bit hesitant. Looks like your dropping the plug down a deep hole and hope you don’t cross thread them…any thoughts?

 

Just grab an extended spark plug socket with an magnet on the end! No problem here except on the driver side where I broke a clip due to my gargantuan hands(still need a replacement but keep forgetting). Should be plenty of YouTube videos showing the entire process so you know what needs to be moved(iirc just one 10mm bolt undone and one loosened on the driver side)

 

Yeah the driver side looks a bit more cumbersome. You broke the coil clip?

 

Driver side front is the tough one. The rest are fairly easy.

To avoid cross threading, I suggest using a mag plug socket and starting the plug by hand. I always spin my plugs in reverse at first until I feel the plug threads “jump” over the head threads so I know everything is aligned properly. Then I begin hand threading them in.

 

Nah, a white clip away from the engine( guess it doesn't matter much if I've left it broken for so long I forgot what it holds LOL), that my forearm bumped when pulling the coil out

 

Yeah can’t be too important lol.

 

Denso Iridium. No change in performance. Just don't need to change them as often. Also Denso are OEM so sticking with them.

 

I replaced with NGK iridium at 86k miles. I’m at 120k miles now with zero issues or change in performance.

 

I found a 2008 TRD Catalogue on TW, Toyota recommended Iridium plugs, P/N PTR24-35070, as a performance option back then

P/N PTR24-35070 is a DENSO Iridium Spark Plug

$9 IKH22 Iridium Power Spark Plug, (Pack of 1)

IKH22

 

Interesting that they show a set of four spark plugs for each of those V6 engines. Hmmmmm.......

 

It just means that the SQU number is for a set of four which is what the packaging comes with. Nissan does the same thing.

 

Just go with the copper denso's and change them every 30k. It's an easy intraval to do a full service; both diffs, transfer case, plugs, oil change, air and cabin filter.
