    Default NGK vs Denso Iridium or Platinum plugs

    Has anyone tried the NGK Iridium plugs in their V8 tundra and if so are you pleased with the performance and gas mileage? I see that the Denso Iridiums dominate the discussions but the NGK iridium is almost half the cost of the Denso.

    For those of you who use platinum, are they just as good as the Iridium with the performance and gas mileage


    Thanks

    I put NGK Iridium IX in my 01 Sequoia and 95 Avalon about 2-3 months ago. Feels that the engine runs a little smoother, sounds smoother, after installation on Sequoia. I bought it because I do not like changing plugs often. Iridium should last longer than regular copper. I dont think there is a change in gas mileage in Avalon or Sequoia.

    Previous to Iridium, the Avalon has platinum for 60K. The Sequoia has copper plugs, but not sure for how long since I just bought the truck last year.
    Thanks

    I use the NGK v-powers in everything I own and have never had a problem.

    We need two guys who both need plugs in their trucks. One guy installs $1.59 Denso copper plugs and make some speed runs. Take those out and put in the iridium plugs and make some speed runs. I don't think you'll see much difference, but who knows? If there isn't any difference, the guy whose idea it was to buy the expensive plugs gets stuck with the cost of them.

    Your talking about the same plug manufacturer. Toyota has been running those plugs for years. The only difference you will notice is with plug life! The iridium will last 50k plus, and the standard will need to be replace at 15k. You might notice a difference if you ran a hotter version with a supercharger or turbo.

    I am running the NGK iriduims on my 2k V8 SR5 and no performance gain. My reasoning for putting them on was longevity of replacement interval. My wifes LX 470 factory recommendation are iriduim plugs. Same engine with a higher compression. Factory recommended plug replacement is 90k miles for here LX 470 ride.

    Thumbs up

    Thanks to all of you for the info. I will probably go with the NGK Iridiums vs the Denso becasue of the $ difference. I can get the NGK Iridiums here in Atlanta (NOPI AUTO PARTS) FOR AROUND $6.25 EACH.

    I have set of the Iridiums in my 01' Tundra. Been in there for about 100,000 miles. Just looked at them last week figuring it was about time to change them but they still looked like new. Well worth the few extra bucks. The first time I had the plugs changed I made the dealer do it (BIG MISTAKE!) I asked them about the Platinum / Iridium plugs but they refused citing warranty B.S. $150 bucks. OW! Fool me once. The next time I put the Iridium plugs in myself. (only took about 10 min. easiest plug change I hav ever done) The next time the dealer looked at the mileage and told me it was time to change plugs I told them (never mind I did it myself) but I didn't tell them I had put the Iridiums in it. A cleaner plug burns more efficiently and gets better mileage and performance. I HIGHLY reccomend them!
