Review on πŸ”₯ Genuine NGK Spark Plug 5858: Your Key to Optimal Engine Performance by John Rodriguez

Revainrating 5 out of 5

Repair Cadillac '67. Even after replacing the rotor.

Rebuild Cadillac 67. Even after replacing the rotor, distributor cap and new 8mm plug wires this gave me consistency. Those V-shaped NGK plugs really seemed to add some horsepower. I usually ride stock, but what the heck.

Pros
  • Spares
Cons
  • Not the best
