This part is not common, and when you can find it, it's expensive. So I bought these on Amazon at a good price and delivered-to-my-door convenience. Win win.

OEM for 2016 Toyota Tacoma 3.5 L V-6

Reviewed in the United States on January 1, 2024

Verified Purchase

These are the OEM spark plugs for the 2016 3.5 L Toyota Tacoma. The original plugs were still in good condition when changed at 82,000 miles as shown in the attached picture. Very little erosion of the center electrode was noted, although I did not measure the gap upon removal.
Installation is a chore, especially on the driver's side, but still much better than paying the dealership cost.

Watch the gap

Reviewed in the United States on March 28, 2024

Spark plugs are OE replacement for my 2019 Tacoma but out of the box each plug had a significantly different gap- none what Toyota specified. Work fine after adjustment.

Packaging terrible !

Reviewed in the United States on September 28, 2023

Spark Plugs shipped with no protection and just bouncing around loose in an envelope. These plugs are expensive and what's worse they are difficult to install. And you wonder why people go postal...
