Denso Iridium TT Spark Plugs-Get Some!

AR technician with the oak leaf clusters above the maintenance badge. We called it master mechanic. I don't know what you guys call it now. I made Tech. In 9 years. But I'm a book worm. I rebuilt my first engine, a Mopar 318, from reading a book. I sent the heads off and the crank off, but the rest I did, by myself, from a book. Put 125K miles on that engine and sold it to another Buck Sgt for $100 when I got quick orders overseas. Only thing I changed on it was I put a 4 bbl carb on it as the primary bowls were smaller on the 4 bbl that the two on the original 2 bbl. Got 3 mpg more by doing that. Probably helped with the rebuild too. Thanks for your service! Hope you enjoyed it as much as I did. I would have stayed in too but got divorced and got custody of my kids. Had to get out. Well, chose to get out. It was the right move for me. Worked as a contractor for FedEx for a while and then hit a mid-life crisis at age 40 and went back to school to be a nurse. Working on people is not much different from working on planes and cars. Weird but true.

 

You learn something everyday. I mean I know plenty about preignition but I had no idea about heat ratings.

A nice side benefit is not having to uninstall the whole TRD S/C every 20,000 miles too .

 

Yup. However I'm guessing it was a two birds with one stone idea. Better heat rating and longer plug change intervals.

 

The main reason I put them in was simply because of the long life.

 

Like I said, I read an article on it 8 months ago. Sounded like a sales pitch. But yes, forced induction causes more pre-detonation. Did you just google that info?

 

Well la de dah. While you were reading posts on here, I was reading the latest on cardiac cases in the ER. Where I now work. I've not done a lot of mechanic reading in the past 10 years, which is why I was on this site in the first place. I based my info off of posts on here that I read, talks with other mechanics who seemed to know what they were talking about, and talking to a service manager at the Toyota dealership. From all aspects, I thought I had the correct information. But I was incorrect and after being rudely told that, I did more research and you guys were correct. Hats off to you. But the snotty comments, well, comes from an inner self-worthlessness. Might want to research that a tad bit.

 

There is a lot of good info on this sight but you have to sort through all the BS and deal with all the know it alls........
No matter what info you bring some ass will start saying your wrong....
Welcome to TW..............

 

And no, I didn't miss your insult either. Just didn't know if I wanted to comment on it. MSGT. That's it. I made Tech in 9 years. 3 classes shy of my BS. On course to make Chief in less than 18 years. And yes, I already passed the 9-level courses for senior enlisted officer too. I just couldn't put the oak leaf clusters on my badge around the star yet. I would think a Master Sgt would know all about that. But anyway, I kept being sent on TDYs all over Europe the last 3 years of my service that I couldn't even finish those 3 classes. Every time I signed up for a class, I got sent out TDY to fix a broke airplane in some God-forsaken country over there. Because you see, for over two years, I was the only qualified Aero Repair technician on the continent of Europe who could do that level of work. I fixed a slat system on a C-5 with just me and a crew chief I brought along and got the flying crew chief to help too. Usually Dover would send out a 9-man team of specialists to do that job. But it was crunch time and I got the call. I was with the 625th out of Rota NAS, Spain, at the time. We moved there after shutting down Torrejon AB in Madrid. Had her flying out of there with over 200 troops two days earlier than expected. I'm quite proud of that. And if all you can do is slam my service, my question to you is, why did you not make senior or chief? But I think I already know the answer. Still. I thank you for your service.

 

From your photo, nah. I've seen your movies.

 

It could be. But I only have a tad over 7000 miles on it. And I check my mileage all the time. My first trip was from Memphis To Birmingham, 240 miles. Got 16.1 mpg and that was in the first 500 miles. Like I said, I rarely ever go 200 miles without filling up. Just old habits. And I'm sure you have way more technical knowledge than I do. Most of my maintenance was in the Air Force on jets and cargo planes. But my grandfather had a shop for 70 years and I grew up in that shop. I've done hundreds if not thousands of tune ups in my 50 years as I've always done my own maintenance. And working in my grand father's shop, I saw all the salesmen day in and out. My grandfather had a very prosperous business dating back to the 30s. I am very familiar with all the sales pitches about this product vs the other one. And I have never seen an increase like this. Had it been just a straight trip on flat roads with no winds, I'd have chalked it up to an unknown tail wind. But I've driven in tail winds before and got a 16.3 once. And the 16.8 I already mentioned, but never have I seen 18mpg. And I had no tail wind today. Just harsh cross winds pushing me all over the place. I'll keep checking it out but I was stoked to say the least!

 

I'M JUST KIDDING! I know you're probably some Toyota engineer who helped design this thing.

 

The 1st time I got over 20 mpg was when I put in my AFE Pro dry air filter. I drove for 75 miles and filled it up. That was also the last time too. Never broke 18 since. That was with the bfg ko2s in 275/70/17.

 

Yep. I did. Maybe I took the correction in the wrong light. Just seemed rude. I mean I posted my results and people post quotes that imply that I am not truthful. Or that I jumped conclusions as if I did no research at all or have never done any research. All the mileage data was spot on. I have learned the information I received on the gear ratios was incorrect and I'm glad I know the facts now. But when you read posts on here on that subject, research it online, hear other mechanics talk about it, then hear a service manager say the same thing from literature he has in the dealership, I figured my information on the gear ratio was correct. Didn't mean to post incorrect information, but it happened. I learn something new everyday. But I've not been a paid mechanic for over 10 years now. I'm an ER nurse now. So when I set out to do work on my own truck, I do a lot of research from a lot of different sources, but mainly from the manufacturer, before I set out to do a job. I watch videos on how to do this or that, especially if I've never done something before. But today, I saw numbers of gas mileage that I've never recorded on this truck and I bought it new, back in July. I've checked the gas mileage on it every time I fill up. From small trips, to long trips, to weekly driving and fill ups. Never seen 17mpg. And this morning I change the plugs, take a trip with strong opposing winds, meaning my mileage should have sucked, and I see 18.6! I've been checking mileage on my vehicles for 34+ years. I know how to do that. And I post on it. And I get posts saying the only thing you will get from new plugs is longer service life; positively implying that I'm an idiot or knowingly posting false data, well, I just shot back. And that's my fault. And then I get questioned about my service in the military and what I posted on that from a senior noncommissioned officer??? That was an insult to his rank, not mine.

 

[QUOTE="Clearwater Bill, post: 1197599

So the dealer told you they needed to be changed in 30k because? They just wanted another $300 for $40 of parts?

And yes, my wife and kids love seeing me. [/QUOTE]

The actual service manual states every 30k just an FYI. Not necessary but that's why......

 

LOL. Yeah, but that SC is awesome! I'd put up with the lower mileage for it any day! I had a chance to buy one before Christmas but opted not to. Spoiled the kids and grandkids instead. But I did watch two videos on how to put one on and even downloaded the instructions from Toyota. But I don't have the ability to do a re-flash. That was constantly in the back of my mind. My Tacoma is my only vehicle now and I'm rarely at home. I'm a travel nurse and I'm on a contract up here in Iowa. I rent a small apartment in the back of a 3-story house that is rented by a single mom and her girls. We share the garage. So they are out of town this weekend and I had the garage all to myself. Pretty day. 50 degrees. So I jumped up and put those new plugs in and hauled butt to Des Moines to get the relay to do the anytime locker on my truck. That was the trip I made. Seems most of the RadioShacks are shut down now and the only one near me with the relay was 58 miles away! Sorry for taking your posts wrong. Just hit me bad I guess. Been away from home too long. Thanks for the info though.
