Review on πŸ”₯ High-Performance NGK Spark Plugs LTR5IX-11 (Stock # 4344) - 4-Pack for Efficient Ignition by Mike Zeigler

Revainrating 5 out of 5

Works as expected

Installed them on my Mazda CX-7 with a 2.5 liter 4 cylinder engine and they were fine. Even though they were "pre-gap", they were all different so I would recommend having a gap tool to pack the plugs properly. Since replacing the original spark plugs with these I have noticed a slight improvement in "liveliness" as the car probably runs like new because it is more responsive when you step on the pedal. Overall good value for the forks and they perform as expected.

Pros
  • An absolute legend
Cons
  • Not as bold as other options
