Lexus RX330 Ignition Coil fires each cylinder with the burst of electricity that transforms 12 volts from the battery into up to 40,000 volts so spark plugs ignite fuel with authority. Early versions of the RX330 had one Ignition Coil that fed a distributor that spun voltage to each plug, the mid-generation Lexus versions had waste spark coil packs where each of the cylinders shared a coil back-to-back, and the recent versions of the RX330 vehicles feature coil on plug units that are right on top of the spark plug for faster response and fewer high tension leads. Regardless of style, all Ignition Coils contain primary and secondary copper windings around an iron core in a resin filled shell, the primary is applied to produce a magnetic field while power is applied, then the triggering mechanism snuffs out the power, collapses the magnetic field, and the secondary generates a high voltage surge that jumps the gap on the plugs. When an Ignition Coil goes bad, the Lexus SUV can misfire, idle roughly, lose power or show a warning light on the dashboard, thereby giving modern Lexus SUV drivers better starts, therefore it is vital for these drivers to make checks on time and regularly inspect an Ignition Coil so that the RX330 can run cleanly. Additionally, ensuring the performance of the Ignition Coil is crucial for optimal engine function.
