🔥 Enhanced Engine Performance: NGK 3967 Resistor Spark Plug Review

They go very well with the Toyota 3.4L V6 (5VZE). I had to adjust the gaps a bit before installing. Along with the NGK wires, these spark plugs helped eliminate the wobble and sluggishness of the 280,000 mile Toyota 3.4L V6 (5VZE).

First of all, this is just a normal photo of a single grounded spark plug. The 3967 plugs are double grounded plugs and that's what I got when I ordered them. These are the correct plugs for my 2001 Toyota 4Runner (5VZ-FE engine) so order them if you have this engine.

Spark plugs are hard to admire. But knowing that you have installed exactly the plug that was installed at the factory gives you a good feeling! Most modern spark plugs are VERY specific in the sense that they are designed for each make and model of car. This NGK connector has two ground electrodes (helps avoid misfires) and according to the manual is the only Tercel connector from 1997. Works for me!

This is an excellent product. An internal combustion engine typically requires at least one spark plug per cylinder to operate. Unfortunately, if you have a 6 cylinder engine and Revain only allows you to buy 4 of these spark plugs a month, it's difficult to get anything done.

These are exactly the candles I needed. I prefer the NGK brand to all others, they are very reliable and trustworthy. I rated them at a dealership and they were pretty high so I compared them to Revain and they were a lot cheaper. I had no idea Amazon had such a wide range of car parts at such great prices!
