Review on High-Performance Hitachi IGC0006 Ignition Coil: Optimize Your Vehicle's Performance by Faten Teller

Hitachi coils are OEM parts. They fit perfectly and work very well. A tip, if one of them doesn't work, replace them all. Especially if the defective one is under the intake manifold. You will not regret it. We did just that, the failed coil pack was under the header. The repair shop repaired and repaired three coil packs and manifold seals because the truck was in Maryland when the coil pack failed. I myself replaced three others on the driver's side when she returned home to Florida. Replacing all six coils ensures reliability. :)
