Review on πŸ”₯ Spectra Premium C-522 Coil on Plug: Boosting Performance for Optimal Engine Efficiency by Chuck Chen

Revainrating 5 out of 5

They fit and work. Hooray!

I mean, really, what more can I say? Those are ignition coils. I chose them because they were 60% cheaper than what my local auto parts store was charging for the same item. I installed them and no longer have an OBD-II code that says "Multiple Cylinders Intermittent Misfire". That was kind of the purpose of buying them, so I think they're great.

Pros
  • Durability tested to 100 thermal shock cycles (-50 to 300 degrees Fahrenheit) to ensure reliability in high vibration
Cons
  • Out of fashion
