Preferred spark plugs?

Some are saying to stay with the oem plugs. What’s your preference?

 

Stock

 

Not a preference issue. OEM. Inexpensive and efficient. Everything else is a waste of money and may cause issues down the road.

While we are at it:
Oil filters: OEM
Wipers: OEM blade inserts

I just saved the internet from 2 more redundant threads.

 

20K miles ago I used Denso 3491 plugs. I bought them from Auto Zone and very happy with them.

Doesn't Denso make the OEM part for Toyota?

 

If it meets specs then I honestly can't see how it would matter. It's just a spark plug.

BTW, when I was a young lad, you could get a run of the mill spark plug at the auto parts store for a dollar each! We would change out plugs just for something to do.

 

All the ones I've bought from a USA dealership have been what looked like a Denso plug.
From the lettering style to the marking color.

That said, Denso does not supply all the plugs for Toyota.
NGK does too.

But from a USA dealership, the ones I bought look like a Denso.

 

Ok, I’ll go with Oem. I couldn’t find them on Amazon but I did find these:

 

Dude, go back to post #1 on this website. If you did that, you would know it is only 50% true.

 

I prefer Denso or NGK. They're more spark pluggish than other spark plugs.

 

i agree with the plug selection, usually get these types of items from the stealer. But what the heck is more spark pluggish ?

 

According to Denso, If you bought your Tacoma in the USA, they are the O.E manufacturer.
Does it matter, Nope. But we can lay the speculation part to rest. (For the USA guys)
Now, go use a cross-reference chart and pick the one you like best.

 

Someone mentioned to be aware of counterfeit parts so I’ll just get them at Autozone. They have Denso 3491 plugs for $23.00.

 

Most dealerships are cheaper. Mine was $16.xx when I looked.
But the price of convenience is worth it at times. The $36.00 saved, is 3/4 of a tank of gas for me.

 

You don't know? Everyone knows that!

 

Stay away from OEM sparkplugs on ebay. Especially, if the price is to good to be true.

I go OEM every time. Like everyone else has said, be aware of counterfeits.

 

This always happens, I end up with a vehicle I can’t get parts for. I called every place in town for some Denso 3491s. None in stock and they can’t even order them. I couldn’t find them on Amazon this morning but I’ll try again.
The last parts store I was at said that NGK 92174 were a suitable substitute.
I hate my dealer but that might be my last hope.

 

Yes, at the time I bought plugs, Auto Zone had a good price.
