    I have only done a lil research that our Tundra manual says to use either Denso or NGK spark plugs but both these offer a small range of diff options within ther groups so I wana hear from Tundra world what u guys use like I've seen from Denso has a fuel saver a performance a standard options as well as NGK has 3 options any one using those other options other than oem?

    yep bank account is running low from it..
    Denso.. I keep with oem. If the plugs are burning normally with good wear and heat range in your engine why change?

    Edit don't believe all the hype on spark plugs once they start to wear, no matter what they are made of, they all go out... ... Bigger thing ecms are good at spark plug burn. Unless you have a (blower) s/c not worth the extra money on plugs.. you not going to save that much in fuel cost do to the ECM relearning the burn rate on the plugs.... On a stock engine keep oem plugs in unless your having problems...

    OEM. OEM iridiums are supposed to be changed at 130K. I pulled out two of mine and stopped. Both looked like new at 60K mark/9 years. My plug wires are amazingly still decent to. Go figure. I have no problem replacing plugs or wires, but not yet.

    I could have stated that better. Although very short, the coil/igniter "wires" are like new at 9 years. To me...plug wires. (Remember I'm an old school fart) I'm assuming that the coils would/or should be replaced at the same time as the plugs at 130K, but don't quote me on that.

    Now you have to inspect the boots on the coil and look for cracks in the case where the coil is at.. if any are found replace the coil.

    The bad now you must have a. Lab scope to prove coil failure or prefailure do to the ECM adjustment in burn. Mainly you look at sign wave and amp draw... Amp draw I look at more than sign wave anymore.

    I think Accel makes aftermarket coils but I haven't found too many good reviews on them. I would guess that it would be best to replace with OEM coils if one should ever fail. The OEM coils must be pretty decent. I don't recall anyone mentioning coil failure here. Yet. Remember when you only had one coil to replace?

    Glad you posted that. I looked in the manual, but didn't see that. I thought I read they were Iridium so I was expecting them to last a while, but wasn't sure when they were supposed to be replaced. In my Tacoma they used Copper plugs and they had to be replaced at 30,000 miles.

    My 86 Toyota hilux has one coil.. always fun bringing out the timing light so you can adjust the distributor...

    My Tacoma last year after 19 years (275,000 miles) the coils where not bad they where noise and back feeding into the ECM.. replace them with Wells and no problems to report.

    You obviously get as much sleep as I do.
    I'll double check my user manual. All change intervals/level are in the user manual. The iridium plug intervals are definitely over 100K.

    Yeah, they should be, I put Iridiums in my Tacoma and they lasted well over 100,000. I just didn't see the interval in the manual. Glanced through it too fast.

    Any specific Densi model number recommendations? I'm seeing quite a few options. Just curious if either is more preferred than others?

    Quick question. Anyone know off hand what plug is best for a 2008 5.7L 4x4 double cab, preferably NGK or Denso? TIA.

    I plan on staying stock. I haven't had a chance to check the manual yet. I would use Roman but I think that I'll have to do it tomorrow during lunch or something. Thanks.

    My '14 just turned over 100,000 and I am getting into a lot of maintenance and noticing a lack of threads where people might turn for answers. So i wanted to post a simple one for people who get up there in miles and are looking to change plugs. OEM spec is to change at 120K miles. So what does everyone use? I know a lot of people like to replace theirs with the Densos. I prefer to run NGK Lasers on my vehicles. Any tuners or mechanics with some good input?

    I've got 8 Densos on the shelf. Gaps checked. Ready. I'm at 48,000 miles. I will do them long before 100,000 miles. Prolly 50,000 when I do the tranny fluid, front & rear diff fluids and transfer case. Oh. And the motor oil.

    I've got the Denso Iridium SK20HR11's and I'm pretty sure (it's Saturday so I'm not walking to the truck to get the manual) that those are the exact ones listed by Mama Toyota in the manual.

    Replacing the sparkplugs for my 4.7L 4wd tundra for the first time. I've heard of that NGK, bosch, or the factory brand Denso as good brands but, I'm just wondering what's the best.

    When I changed plugs on my 08 Tacoma I just got them from the dealer. They gave me 3 ngk and 3 denso. Lol. Sure enough when I took the original plugs out....there were 3 of each. Weird but I guess toyota does this. Anyway, there is no "best". Just get whatever was in the originally, dealer is usually as cheap or cheaper than a parts store.
