My 2017 Tacoma uses this Denso as well. Although this is a long-life plug, the OEM recommends a 60,000 replacement. The removed plugs showed no appreciable wear. Thank you Petr, for sharing this information. The auto parts sellers will try to substitute a cheaper plug to look like they are giving a bargain.
Is your 🌮 4 or 6 cyl? I have a 2017 equipped with V6. Currently @ 140k miles Truck was under service contract when a stealership replaced them first time in 2019 with around 60k mileage. Didn’t question it that much being I wasn’t charged anything. Trying to stay up on all maintenance for this vehicle as I drive long distances frequently. I suspect that my plugs don’t need replacement either. Wouldn’t bother me to just do it if it’s actually necessary. It’s really annoying that Toyota doesn’t give accurate info on how to maintain their cars. How can you trust data that suggests you should wait 10k miles in between oil changes 🤥
😂 Toyotas I'm a straight up Toyota-Nerd! Especially for their OEM parts lol but every single time I watch your channel I always repeat it with you say "Toyota RUclips maintenance channeLLL!!" 😂👍 I LOVE YOUR CHANNEL KEEP UP THE GOOD WORK! 👏👏
That is an amazing design, but I must say that I got great service out of the OEM NGK iridiums in my '04 Forester XT. No sign of any need to change them by the time I sold it at 135K miles. Thanks for the video.
This is what makes some people think their mechanic isn't being honest with them, or over charging them... Some people forget quality makes things last longer!
Well Peter, I've got 2 Toy. Corolla's, and a Chevy Blazer (91), and a 1975 Honda CB400F/ supersport, and a Yamaha XS1100/'81, and I run them "ALL" on Pulstar, pulse-plugs, and when I've bought them, they've costed from as little as $14.99 up to $17.99, some years ago with the latest plugs I've bought. They're the Iridium also, > by the way, Toyota Prius , back in 2010 began to use/equip them with THESE Exact plugs! I don't know if they still use them, (I'll bet that they don't since now "they" make they're own). But they did, and it's a "CAPACITOR" spark plug,,, so the massive energy that it holds, goes to the combustion chamber to give the COMPLETE burning of gasolene. I've used these plugs since 2008, after seeing them advertised in the back of Popular Mechanics Mags. and Popular Science mags.
I replaced as recommended the plugs in my 2014 RX 350 at 120000 miles with the OEM plugs and I hope to drive 140000 miles or more before replacing them.......My vehicle was running great and no issues but i replaced them because the manual advised.
I run the Denso Iridium TT plugs and noticed a slight difference in how the vehicle runs. The motor seems to run smoother and is more responsive. I let those plugs go for 100k miles before changing them out. In my experience changing them out any soon then factory recommendations is a waste of money. 2007 5.7L Tundra 250k 2014 5.7L Tundra 114k 2017 3.5L Tacoma 100k

How timely Peter. Tomorrow morning I am installing NGK Ruthenium HX plugs in my 2009 Matrix 2.4 liter engine (195,000 miles). I wanted to try something new and got them for a very reasonable $10.00 CDN (American pocket change) each. I love my Denso alternators and rebuildable gear reduction starters in my smallblock Mopars. Even had a lot of luck with Denso plugs over the years in Mopars. The NGK V-groove plugs have worked very well in the Mopars too. I just wanted to try the Ruthenium plugs in the Toyota runabout because they're the latest development, with some pretty heady claims about outperforming iridium. Perhaps I'll be running back to Denso iridiums? We shall see. It's not like I'm screwing in fifty cent Autolite Coppers from Walmart. Wish me luck Malcolm Ottawa Valley
Just finished swapping in the plugs. That was a cake walk, you lucky Toyota devils you! Only four plugs and all easily accessible. I was done faster than I could believe. All came out fine. None too tight, none too loose. The inner two tubes had signs of a little oil in them, indicating the sealing rings of the valve cover gasket weren't doing their jobs on those two inner tubes. I gently snugged down the two middle 10mm bolts(nuts?)ever so lightly. They weren't loose or tight, but maybe that will stop the "internal" oil leak around those two inner plug tubes. The two outer plug tubes were dry as a bone, as was the cylinder head's exterior. The plugs were all a healthy color of light tan, with no oil on them. Only the passenger's side plug looked slightly over gapped, probably from use, wear, miles and age. It started fine, idled down smoothly. Haven't driven it anywhere yet. Going out to a pool for 1pm(it's already 86/94 in the shade here), then we'll see if I notice a difference. Changed the oil and filter too. That's a cake walk too you lucky Toyota owners. Didn't even have to jack up the car! Stay cool, we're roasting here. Malcolm Ottawa Valley
@@rightlanehog3151 No it's not, in spite of the high mileage. It's a hand me down from my brother who changed his oil religiously. Beat the whee out of it, but serviced it very well. Was out for a swim and drove it a good 20 miles there, back and around. Conclusion? The car likes the plugs. It accelerates more effortlessly at part throttle, cruises very smoothly and seems to be doing less rpm at every speed(if that's possible). Haven't got on it, as we are being punished by our Prime Minister with a needless, hurtful carbon tax and gas is wildly expensive here. Really have to vote that economic imbecile out of office asap.

My brother isn't just a discerning Toyota owner (has two Rav4s right now) he's also a world renowned hydro geologist. He informed me that Ruthenium is part of the iridium mineral family, just harder. I've learned something today. Malcolm Ottawa Valley
I have a 2011 camry le and i had the original plugs replaced with denso iridium plugs, runs like a top and very smooth idling and acceleration. and fuel economy went way up
This video is not complete without including information about the dangers of purchasing and using counterfeit Denso plugs. If you're buying from Amazon or eBay at a substantially reduced price then this is the risk you are taking.
I wasn't so smart I bought Denso Iridium single tip when I went to change them it had NGK dual electrode iridium installed and it had a sticker on the valve cover for the NGK dual electrode iridium on my 1999 Toyota Corolla LE 1zzfe
My 2013 Tacoma with the 4 cylinder 2TR-FE specifies 120 Kmiles or 12 years. Got 105K on it now. My miles traveled per year on that vehicle has dropped to 1500 (1.5K), so I guess those factory Densos will be in there a while longer.
Don't be Stupid!!! Pretty much, just stick what Mother Toyota recommends...DENSO.... There is a reason why these Engines last for over 300 thousand miles!
Did Petr mention how many miles are on these plugs in the video? If he is changing them I'm assuming they have 60,000 miles on them. They look like they have at least another 30,000 miles left in them.
I always use the Denso twin ground (PK20TR11) in my 1MZ-FE V6. However, the dealer charges over $15 each here in Canada. Still, they last over ten years so the expense is negligible. I never knew they made a tri-ground spark plug. Thanks for the info.
My first choice is Denso as well, but what issues with NGK did you have to consider them trash/мусор/хлам? I have never seen you post a reply to comments, but I think it would be helpful in this case. As for cost, I like to order from Toyota dealers websites, but they usually charge outrageous shipping for just four plugs, even with good pricing.
Maybe depending the application. See how at the end he says the same spark in a prius is scheduled at 100+k replacement maintenance In a Taco the spark plug is more abused at higher RPMS for longer and in the Prius is much less. The same as treating engine oil in a car, it could recommend 10k mile replacement but it really depends on driving style
@@jeffjohnson6252 I think I had heard that as well somewhere, but I don't really get it. Why just this engine? Does it affect performance or engine health in any way? I'm going to go ahead and do it, but I'm a bit resentful if it's just to satisfy the environmental bean counters.
I noticed my original Denso plugs from my 2rz-fe were made in Japan, but now they're made in Indonesia. It raised an eyebrow, but I'm glad it's not China. I don't want to help them build more super carriers.
Hello! I just replaced spark plugs on my Lexus GS 300h with a newer version of this plug, IKBH20TT which has a thinner electrode of 0.4 mm instead of 0.7. I was curius about the differences since both the new one and the one in the video is allowed.
I have to admit, I've never seen a 3 ground electrode plug that looks like that one. I think it's designed to compensate for the fact that the plugs aren't indexed.
Indexing your plugs keeps the ground electrode away from the incoming charge thus exposing the spark exactly to the gas. Thus, the combustion is smoother in all cyls. I tried this and it is true. Also, NGK makes a Ruthenium plug which is better than Iridium. What is the resistance of an Iridium ( any make ) compared with a Ruthenium plug? People want answers. The people are angry, aggressive, and violent... And forgetful. I forgot what I was just thinking about. Oh, well.
I have a 2015 Tacoma 4.0 that I bought new. I changed the spark plugs and the passenger side it had Denso and the driver side NGK. Just wondering what your thoughts on this.
Hi bud love your videos, I have a 2006 tundra with 4.7L can you give me recommendations on spark plugs, I bought it 8 years ago with 40,000 miles on it, it has a NGK plug in it, Toyota says they use Denso plug but won’t give me the number, said it has always been denso so I wonder why it has NGK plugs in it, I doubt someone changed the plugs before 40,000 when I bought it, if you have the correct denso plug number so I can get them I would appreciate it. Thanks
IFR6T11(NGK) sk20r11(Denso) I believe both of them do OE. I'm not an expert, but I've had OEM parts of a different brand than the original parts currently sold by the dealer on several of my own Toyota/Lexus vehicles. I'm sure either one will work fine, judging from my experience. Together we can wait for this well-meaning professional to come up with a better answer than mine.
Ya can't run any spark plug in Toyota's, it must be either NGK or Denso. Because if you use something like Auto Lite, AC Delco, or Champion..........they WILL foul ( these spark plug brands ) very soon. You lose optimal efficiency, power, and suffer with poor gas mileage. My buddy has been a certified Toyota tech for going on 30 yrs, and he's the one who taught me this. Also, around 6 years ago, another friend installed Auto Lite spark plugs in his wife's 1st gen Tacoma ( 2.4 liter ), and sure enough, her truck started stumbling during acceleration and she got poor gas mileage. Upon inspection, he noticed that all 4 plugs had fouled, even though they were only about 4 months old. She doesn't even take long road trips very often. It backed what my Toyota tech friend had told me, and I'm absolutely convinced........at least for the engines used in the 1st gen Tacoma's & 4 Runners: the 2RZ, 3RZ, and 5VZ engines. Probably true also for the other Toyota engines.
