Why Autolite .032, Denso .044?

Both are platinum and Autozone indicates they both exactly fit my 2003 Tacoma 2.4L. My current dealership bought Denso were the OEM copper ones and were factory gapped at .032. Anyways, I'm going platinum. The dealership only lists 2 Denso OEM plugs in their book, the copper ones or the OEM iridium ones and they want $50 for the iridiums. I want to buy Denso oem at a savings but am wondering why the difference gap sizes as my OEM copper ones were .032.

 

Sparkplug Manf. gap means nothing.....
Gap them to where theyre suppose to be...
Should state / list gap on the emissions sticker under the hood...


Those plugs fit numerous / tons of applications & not specifically built & gapped for your taco...
They picked a base gap & went with it, doesnt mean its correct or even close for your application

 

Ha! That didn't help me one bit. Generic answer.

 

If you say so....
Why are you concerned with a gap that means nothing?????
Just trying to point out that youre concerned with a gap that is totally irrelevant.

 

Never ever auto lite on a Toyota. Toyota is almost always 0.040-0.045 there's no reason it should have been less.

Stick to 0.044 NGK or Denso, you can go platinum or iridium no issue, it just increases the intervals. I kinda prefer the cheap coppers because its so easy to do on that truck.

 

NGK or Denso is the way to go. Check on Rockauto for them as well. Definitely stay away from Autolites. They suck.
I've only ever used Iridium's in forced induction applications. IMO they are waste of money for an all motor truck that's used for regular driving.

 

Lol wtf.

You always gap your own plugs. Iridium/Ruthenium did not exist when these trucks were made, so make your own choice, spend an extra dollar on a gapper, then gap them properly

This ^^^^^^^. Who the hell cares how they are gapped from the factory. I’ve never installed plugs that I didn’t check the gap and adjust it if necessary. Even if the gap is stated to be to spec for my vehicle, I still check them. I’ve had to adjust many. Just check and gap them yourself.
