Review on Enhance Performance with DENSO # 3461 IRIDIUM LONG LIFE Spark Plugs - SXU22HCR11S (4 PCSNEW) by Mark Patterson

Revainrating 3 out of 5

It's made in China!

It was disappointing to learn that these Denso spark plugs were not made in Japan. As long as they work well I don't know how long they will last compared to the OEM that came with the 86000 machine. I will be more careful to make sure I get the ones made in Japan.

Pros
  • High marks for support and durability from testers
Cons
  • I won't say anything
