This Ignition Coil is a vital part of the ignition system of the car; it is famous for durability and efficiency. This ignition coil effectively charges low voltage from the battery to the high voltage required in making sparks to combust the fuel in the engine's cylinders. Buick Rainier was manufactured between 2004-2007; hence, the sparks plugs are compatible with a distributor ignition and coil-on-plug type. This component should ideally be replaced at a frequency determined by the vehicle owner; but its general condition does affect the Buick Rainier's performance; leading to rough idle and low fuel efficiency. The optimum function of the ignition coil thus improves the quality and safety of Buick Rainier ultimately leading to comfortable driving. Most significantly, the Rainier's powertrain combinations such as the 5.3L Small-block V8 engine together with the ignition coil provide commendable aggression. Furthermore, the Ignition Coil is unique in the automotive market because of its superior components and durability to heat and vibration which prevail in the SUV vehicles. Other noteworthy features include all-disc antilock brakes as well as GM's StabiliTrak system; further, the Buick Rainier's ignition coil supplements a trouble-free, safe, and comfortable driving experience for the individuals inside the car. All in all, it can be said that the Ignition Coil is a critical part of the vehicle and hence is recommended for the owners of Rainier to get it.
