Spark Plug recommendation

I just changed mine this weekend. I had regular Denso plugs and got about 100k miles out of them. I replaced the with regular NGK plugs just cause they didn’t have Denso in stock. Anything will work just fine. Just depends on which ones make you feel better.

 

Next time I'm getting the new Unobtanium Octo-Core Liquid Metal Nascar plugs with Mega-Spark Transfer technology. My mechanic says I'll really notice a before/after difference in my wallet. For an extra 39.99$ each he'll coat them in special XtremeGrade Oxi-Clean for anti-fouling protection

 

I second that

 

Does the Denso and NGK iridium spark plugs come pre-gapped already? And is the gap .044" for a 2nd gen Tacoma? If I check it just for assurance does it matter if it's a little off smaller/bigger gap. Just need some confirmation as I am planning to swap out the plugs when the rain stops here.

 

I recommend just using the Denso copper stock plugs:

$7 90919-01235 Toyota Genuine Spark Plug

90919-01235.

 

You couldn't spring for the "new, old stock" Splitfires with split probe technology?

 

Ah the old Splitfire’s, that’s a walk down memory lane!

 

Reviving an old thread, but my 2003 PreRunner V6 has a sticker warning to only use twin ground electrode plugs, but most links I see show the single ground plugs.
As a new Tacoma owner (actually hoping to pick it up this afternoon) I just want to make sure I'm not missing something. I'm planning on copper NGK 3967's based on that ominous sticker on the engine.

 

It says that you have a 2003 Tacoma, you need to post in the first generation forum and I'd recommend use the OEM recommendation in the owners manual.

 

I cannot believe I didn't read which forum this was in before replying! I found this thread when searching for 1st gen spark plugs but didn't even look, doh!

 

Yup nothing fancy, I just use the recommended Denso copper plugs recommended by Toyota for my 2nd generation V6. Like I said earlier, I’d just look in the manual and use whatever Toyota recommends for the V6 1st gen.

 

I use a 6-8" length of clear poly tubing that is tight enough to grip the top of the plug (but not too tight) and use that to get the plug started. I can feel the plug start to thread better than I can with a socket + extension. Once the plug is started, you can just pull off the tubing and replace it with a socket. Don't forget to torque it to specs.
