Spark Plug Decision

Can those dual tip densos be used in the 2.7 four cylinder engine?

 

not trying to be a smart ass, but just use the type the owners manual tells you to use. the 3.4 has a slave coil system (3 coils fire the motor) that is why you need those on the motor, not on the ball at all with the needs of the 2.7 but on our trucks it is the safe bet to use what the factory tells you to use.

and again it can be said its wasteful, but I don't push plugs past 30,000 miles.

 

First time I changed my plugs form the factory. It had 3 densos on the driver side and 3 NGKs on the passenger side. WTF toyota oh thats right the plants in Tennesee uh-yep uh-yep.

has anyone tried those e-3 plugs

 

What the hell are you talking about? All 1st gen. Tacos were assembled at the now closed NUMMI plant in Fremont, CA.

 

This ^^. It's NORMAL to get 3 Denso and 3 NGK plugs from the factory. You're quick to cast aspersions from a position of ignorance but, then again, you're just a FNG uh-yep uh-yep.

E-3s are snake oil. Those of us who've taken the time to learn The Truth about Spark Plugs stick with OEM (Denso or NGK).

 

The reason for this is that the heads were assembled in different plants (left vs. right) and the manufacturer (Toyota) didnt specify the type of plug therefore Toyotas come stock with different plugs in each head..
Now you know.....this is a FACT!

Change plugs every 30K with OEM and you cant go wrong!

 

I just changed mine and used factory plugs (Denso) bought from the dealership.

I also changed my spark plugs wires, bought NGKs online.

At the same time I also cleaned my MAF and throttle body thoroughly and tightened up my throttle cable (lots of slack).

All combined my truck runs, and idles, ideally right now.

Can't wait to see the next fill up to see what a full tank yields in terms of mpg

Sorry for the off topic but how do you tighten the throttle cable? Is there a thread I'm not finding?

 

It's the last blurb in this write up.

It's super easy.

And FWIW it was two 12mm nuts on my truck, not 14mm as it says in the write up.

Thanks, I already cleaned everything else and added the gasket. +1mpg so far. The plugs will be comming soon.
