Reliable Ignition Service for Buick Lucerne Sedans
Thermal cycling and extended mileage gradually degrade factory ignition components, leading to weak spark delivery, sluggish throttle response, and unburned fuel entering your exhaust stream. Our complete replacement packages provide fresh secondary ignition hardware to restore factory firing reliability. When servicing your powertrain, explore our full inventory of ignition parts compatible with Buick vehicles or pair your service with a performance tune for Buick for refined drivability.

Frequently Asked Questions
What engine configurations do these Buick Lucerne ignition kits fit?
These packages fit select 2006 to 2011 Buick Lucerne sedans equipped with the 3.8L V6 (2006–2008), the 3.9L V6 (2009–2011), and the 4.6L Northstar V8 (2006–2011). Always match your model year and displacement before ordering.
Will replacing worn coils clear misfire trouble codes like P0300?
Yes. Diagnostic codes such as P0300 (random/multiple misfire) or cylinder-specific codes (P0301 through P0308) frequently stem from failing coil windings or worn plug gaps. Installing a matched coil and plug set restores consistent voltage delivery and eliminates spark blowout under load.
Why are these coils bundled with spark plugs?
Installing new ignition coils over aged, eroded spark plugs forces the new coils to operate against excessive resistance, which can shorten their service life. Replacing coils and plugs simultaneously guarantees proper gap clearances and optimal electrical load across the entire ignition circuit.
