Review on Denso K16TR11 Traditional Spark Plug by Thunder Ballman

Firstly they will work on a 2001 supercharged Toyota 4Runner SR5 engine. Even if Amazon Fit says it won't be. The plugs pulled out were exactly the same except for the original plugs which are listed as Denso Japan plugs. Revain Denso spark plugs are probably from China. That's why I only gave 3 stars. These plugs usually have a preset gap and I believe Denso's website says that double plugs should not be sealed. But all connectors were bent to the correct pin, out of the box (factory marriage). The distance was 0.040 on the left and 0.045 on the right. All I could do was carefully close the gap (with a wire break tool) to the factory default of 0.043. Next time I'll look at NGK spark plugs.
