Need to change out original spark plugs

I have a 2012 4x4 Tacoma with 4.0 L 6 cyl. engine, and 73K miles. Current Spark plugs are original, but I plan to replace them myself. Dealer quoted me $227 to replace them. Please provide advice on the best recommended replacement spark plugs for my truck. The dealer parts department recommended plugs that were the OEM standard type at $3.98 each with a service life of 30K miles. Should I stick to the original OEM plugs?
Thanks in advance for your help.

 

Yes I went with stock Denso’s.

 

You might get varying answers to your question about sparkplug choice....With that being said I went with the OEM plugs from the dealer given they meet manufacture's specifications and the price was unbelievable and unbeatable. You might want to change out the PCV valve when you're at it....its easy to do when you change out the plugs.
Check out some of the other forums here at TW on the suggested way to tackle this project...have fun and enjoy.

 

Toyota OEM denso plugs /thread

 

OEM

 

You drove 73K with OEM spark plugs. What makes you think you cannot go at least 50K on the OEM standard type for 4 bucks apiece? Spend the $16 and do it yourself. Easy.

 

I meant $24

 

I went with Denso #3421 iridium long life. If I remember they were mostly all gapped perfectly out of the box. May have had to adjust one of them, this was 2 years ago though so not 100% sure.

 

I also used OEM Denso


Here is a Great DIY I referenced when doing mine.

I went with OEM Denso's !!!!

 

If they are the originals, there will be Denso's on one side and NGK on the other side. I've done 5 plug changes and went with Denso's each time.

Here's a link showing the process :https://www.tacomaworld.com/threads/how-to-spark-plug-change-1-gr-fe.30479/

 

70k is about right for spark plug change. 30k is overkill. Stick with what the parts department sells. It’s cheap enough.

 

I used oem densos.

Look for a thread titled spark plugs anti seize something something. Seems everyone has their own right way to do it. Torque to 13 ft lb. Use anti seize. Don’t use anti seize. Tighten 1/4 turn after the washer contacts.

I like to center AND gap the new plugs to the closer end of the spec. Sometimes the hook isn’t centered, a wrench and pliers to slightly twist it gets it centered. Put anti seize on them, if the head is aluminum definitely don’t skip this step. Put them in tight without a torque wrench. Never had issues doing it like that except if the guy before me didn’t use anti seize. But doing a helicoil repair on a spark plug hole isn’t too difficult. Trying to find a helicoil kit when you need the vehicle to get to work tomorrow can suck.

There’s a video that explains exactly step by step how to change your plugs. Getting at one on the driver side that’s buried, the video definitely helped.

 

Like others have stated, go with Denso's. Little more involve than a simple Honda accord level but still easy to do. Follow link posted by 08TacoTRD above.

 

Oem. But you dont have to buy them through the dealer. The part numbers for NGK and denso plugs should be listed in the back of your owners manual. Just buy em at Napa or wherever and save a few bucks.

 

OEM Denso.

 

OEM Denso/NGK.

As others have stated, don't buy them through a dealer as you'll pay their markup price. I was lucky a few years back and found a member on here selling a whole case (several spark plug changes worth) for a great deal.

 

why......if I heard this guy right.....he went 700K miles on original plugs

 

Or a even better option is to get the Toyota part number, then plug that into a search on Amazon. It's very likely you'll end up buying from a Toyota dealer, and a much cheaper price than what you'll pay if you walk up to the parts counter.
