The NGK direct ignition coil boot bridges the ignition coil and spark plug on GM 1.4L turbocharged engines. It is molded from premium silicone and includes the internal spring and ferrite resistor needed for reliable spark transfer and RFI noise suppression, built to OEM tolerances for a factory fit. NGK recommends replacing coil boots whenever the spark plugs are changed to prevent flashover and misfires.
