Questions and Answers

What is a "Waste-Spark" ignition system?
In this configuration, the ignition coil fires two spark plugs at the same time—one on the power stroke and one on the exhaust stroke. This reduces the number of coils required but makes proper lead connections and coil health essential for smooth engine operation.
How do I know if my 27301-38020 coil is failing?
Common signs of failure include a rough or "stumbling" idle, a significant loss of power under load, or misfire codes (P0300 series) affecting pairs of cylinders.
How can I ensure compatibility with my vehicle?
Due to variations in regional engine configurations for the G4JS/G4JP, please use our WhatsApp link to provide your chassis number (VIN). This allows us to confirm your specific harness style and ignition requirements.
