Review on πŸ”₯ Pack of 4 Autolite 4303 Copper Resistor Spark Plugs for Enhanced Performance by Chris Kirby

Revainrating 3 out of 5

Something is wrong with the fit, but I don't blame the seller.

Bought these for my VFR750F RC36 but after unplugging (NKG) and comparing the threads don't match! And if screwed in that deep, it could damage the cylinder or improperly seal the crush washer. The funny thing is that "Advanced" car parts also fit. Long story short, after comparing the spacing in the thread pattern and the lack of a top extension like NKG's, I bought NKG spark plugs and decided I'd pass them on to the next owner rather than wasting time and money to Sending back $15 spark plugs.

Pros
  • Spark Plugs and Wires
Cons
  • Zero
