Frequently Asked Questions
Will new ignition coils resolve trouble codes P0300 through P0306?
Yes. OBD2 diagnostic trouble codes P0301 through P0306 point to cylinder-specific misfires across your V6, while P0300 indicates random or multiple misfires. Swapping out worn coil packs restores proper secondary voltage to the plugs, eliminating misfire events and clearing associated hesitation codes.
Should I replace all six ignition coils and spark plugs at once?
Replacing all six coil packs and spark plugs simultaneously is strongly advised. Because the rear cylinder bank (cylinders 1, 2, and 3) sits close to the firewall beneath wiring and intake components, doing a complete service in one session saves significant teardown time and prevents cascading failures on older coils.
What is the difference between RL coil-only packs and coil-and-plug kits?
Our 2001–2003 Acura RL inventory includes a dedicated pack of six standalone coils. For 2005–2008 3.5L, 2009–2012 3.7L, and 2014–2020 RLX models, we offer bundled kits that combine six direct-replacement coils with matched, pre-gapped iridium spark plugs for a comprehensive ignition refresh.
