Review on Spectra Premium C-591 Coil-on-Plug Ignition System by Juan Moncrief

Revainrating 1 out of 5

cheap and eventually broke

installed them - they worked for 6 months after which i started to feel small misfires. then catastrophic misfire 2 cylinder. I thought the cylinder head gasket had blown! But I switched back to the old ones and the car ran fine. It's cheap and doesn't break Buy I want a refund

Pros
  • coil boots on plug
Cons
  • modernity
