Each Lexus RX330 spark plug is designed to endure extreme temperatures present inside the cylinder. It has an insulated passageway that conducts high voltage to the electrode. A ceramic insert keeps the spark from occurring anywhere except the tip of the electrode. At that point, the voltage jumps the gap and is conducted to the engine block. If you have questions about RX330 performance spark plugs, ask our friendly staff members at your local store. We also offer free engine diagnostic testing and battery testing at every location, as well as a handy Loan-a-Tool program you can access for easy, DIY installation.
