2010 2.7 Spark Plug change

Oh Boy! I just changed very expensive original equipment IRIDIUM plugs (that looked great!) on my Taco at 14,000 miles with "cheaper" E3.68 special diamond fire plugs.

It started; that's good. I idles smoothly, wait very very smoothly.

Took for test drive.

The engine is building ALOT more power (torque) and off a substantially lower idle than before!

I will take the truck on the Highway, soon.

That's to been seen. They weren't a joke on my 2.4 93 Hardbody, though. We'll see.

I felt HUGE difference in power when I installed my TRD shift knob, it was so sever that I almost went through the sound barrier...

 

You get about 80-100k miles off those "expensive" plugs according to the manual. I will check mine at 50k and 75k to be sure, but I think all you have done here is made your required plug change 30k miles now. 3 sets of those e3 plus probably is equal to those iridium aka just as expensive. Glad your happy though. Enjoy.

 

You're right; I will be replacing them in another 12,000 or so miles but IF they get better performance and more importantly fuel economy, that's what I need. If I'm not happy (I'll let you all know) I'll be buying new Denso Iridium right away and consider it an edjukashun.

Steve

 

Yeah man me too. I wanna see some dyno run numbers on those TRD shift knobs.

 

You, too are correct. I just go by my right foot and weekly gas expenses as my dyno. My grey leather wrapped Hurst T handle shit knob does make my truck faster, though

Can't you fuckers just let the OP have a good feeling about this. A damn shitstorm hit the fan and now he feels a need to defend himself.

We are all not friggin experts, but we do have one thing in comman ... we all own and drive Tacomas.

Not to make a generalization but I am sure that each of us did not wake up one morning knowing everything we need to know about our trucks. There is a learning curve.

It is a beautiful day out there, get out and enjoy it.

Just my 2 cents worth ..........

 

OK, I've driven the truck on the highway. The engine is running alot smoother. Not much more to say other than what my fuel consumption will be.

Do you honestly think I want to F around with spark plugs and headers? Frankly the fuel economy and more importantly idle economy - how much fuel it uses just idling has been a huge F----N disappointment.

I find it hard to understand why my 93 2.4 4x4 Hardbody (w A/C) got literally DOUBLE or MORE the fuel efficiency.

There is not much more I can do. I will review this vehicle over the summer and hopefully it meets my needs; Christ knows the driver seat and windshield seal don't and if I HAVE TO, I will get rid of it. Trust me.

Thank you for letting me rant. I feel better now. Yes, by the look of it the Frontier is alot worse in every way.

I've just put on 60 highway miles (and 60 yesterday) and the truck runs awesome. I'm nicely above 1/2 tank of gas well into my second week of driving.





Steve

 

I'm into my 3rd day with my E3 plugs installed. I can say the engine idles very smoothly and accelerates strangely quietly.

It appears I may sail right through my 2nd week of driving; I am now at exactly half a tank of gas used in 1 1/2 weeks of driving and that's not bad at all.

I may have to try the twin electric leafblower "superchargers" next. Iit worked for Hot Rod Magazine!

After defending Toyota in a lawsuit over failed spendy aftermarket spark plugs 7 years back, I think I will just stay with the OEM plugs at this point in my 2011 TACO.

Glad to see that the newer "cheapies" are working well for you.

 

Well, I have had the E3 spark plugs in for two weeks now and have driven the truck a full 3 days longer to refuel than before the install. So, my right foot dyno seems to indicate about a 12 percent or so improvement in fuel economy (with the header and plugs) which is extremely acceptable for me.

Before the plug install when leaving from a stop I'd almost have to feather the throttle (or the engine would shutter a little from it's idle RPM) but now the truck leaves without throttling and pulls great.

Obviously the camshaft is made for low rpm up to around 65 or so MPH. I'd love to install a hotter camshaft. Does anyone make a performance cam for this engine?
