Den so iridium tt plugs?

Den so iridium tt plugs? So I have some what's the verdict on these plugs?
Part number

$8 ikh20tt iridium TT spark plug, (pack of 1)

ikh20tt 4704.

 

Regular Denso K20HR-U11 is all you need. No benefit to running the iridiums.[FONT=&quot][/FONT]

 

Well I have them already .no issues with them ?

 

if you have the V6 stick to the standard style denso or ngk plugs.... no need for the fancy high prices plugs.

 

NGK plugs....the end

I run them in everything I own with a spark plug.....will never switch to anything else

 

Just changed mine at 33k. I went std. Densos for all 6 based on something's I read. Glad I did. NGKs were all much harder to get out and gaps were in .046 range. Densos came out easy and gaps were .042.

 

I'm not sure about running the iridiums in the 1GR, but my old '87 MR2 with the 4AGE ran worse on iridium plugs and better with standard copper.

 

+1 for standard coppers - either NGK or Denso (or both)

I swapped mine out this time last year with some Denso iridiums - absolutely no benefit. Iridiums are only needed for use with the Supercharger.

Coppers are cheap enough, change them @ 30k or earlier.

 

I've read that some people have problems running iridiums in the 1GR. Others don't. Copper seems to be the safer bet and are known to be OEM. As for Denso vs NGK, the NGKs I pulled all wore a lot more (larger gap) than the Densos. Therefore I stuck with Densos all around.

 

Been running E3's for almost 2 years, no problems. Haven't looked at them, supposed to last 100 K miles, got like 40 on them. Maybe I should take a look at them.

 

I decided to run these since i had them, getting worse mpg that the worn out coppers... I was getting 20mpg now only 17mpg. Going back to the coppers

 

P.S. Im VVT-i in damn near stock form minus the k&n replacement filter

 

I've been running the NGK iridiums

$39 LFR6AIX-11 - 6 PCSNEW

LFR6AIX-11 for the past 80K miles. MPG has always been the same - 16-18 mpg depending on load and speed. It's the OEM plug on wife's Lexus which is running on 2nd set with 180K. The only reason I got them was for longevity (not having to replace plugs every 30K); truck runs smoothly and responds well. Running Iridiums on my other Toyota's with no issues.

 

I bought irridium plugs. No issues 2k miles later. I used to have issues starting but since replacement of factory plugs at 35k miles I have no issues. It coukd just be a coincidence though.
Me personally I like only replacing my plugs every 100k miles like the rest of the world. I also don't irrationally freak out I'm doing something different than the holy Toyota engeneers recommend

 

I've had the Iridium plugs in for 30k miles with no problems. Even wit 33s and hundreds of pounds of extra weight, I still get about 18mpg in the summer.

 

Is that mpg with the adjusted miles? I find it hard to believe.

With larger tires, your odometer will read less miles covered than you are actually traveled. Best way to determined the difference is with a GPS. I used two to figure out my 265 70 R17 tires cover 1.05% more than the OEM 265 65 R17 tires. So, when my odometer shows 100 miles, I've actually traveled 105 miles.

 

Yes, that's making the adjustment. In the winter, I'm at about 16.5. My summer psi is 40, winter is 35. Seasonal blends of fuel obviously factor in. Also, the fact that I drive a manual and can adjust my shift points for efficiency is a very important factor as well as the fact that I spend very little time over 60 mph - I mostly drive country roads. I was getting worse mileage with the 265/75/16 tires I was running before this, as they were a softer compound.

I'm a bit of an exception, I know most people don't see these numbers. There's been a lot of trial and error, but it's been fun. In addition to my armor and fiberglass topper, I carry a shocking amount of weight in tools and other gear on a daily basis. I do the math for most fill ups. If I figured a true average, I'd be much lower. I put on a lot of miles creeping on rough Forest Service roads and wheeling deep snow in the spring and fall. The mpgs I stated are for my tanks that are mostly asphalt without towing a trailer. I'm closer to 15 when towing a loaded trailer - again, mostly under 60 mph (one of the most important factors to achieve these results). I think another important factor is that I'm still running a stock bumper. When I go to 4.10 gears I'll probably take a hit too.

 

Gotcha. I have the heaviest OEM Tacoma - 4 door long bed 4X4; and with heavy deep lug mud terrain tires. When I drive in Mexico I can get 17-18 as I rarely go over 65mph. At home in San Diego, I'm mostly 70-75 on the highway, with AC on; so my mpg is usually 15-16. My air is 36 psi year round, except when I hit the desert.
