NGK 6700 (RE7CL) 6701 (RE9BT) And 4858 (ZE81) Tune-Up Kit For Mazda RX8

NGK Spark Plug Wire Set is designed specifically for noise suppression and superior conductivity. It is constructed from durable material which enhances the overall strength of the wire providing a super strength backbone on which the various layers of the wire assembly are formed. This wire set uses high quality EPDM and silicone coverings to resist heat, oil and chemical damages for increased durability. Each ignition wire is fitted with a positive locking, corrosion resistant stainless steel terminal end for tight fit and maximum resistance to vibration, separation. It is numbered for easy cylinder identification and coil wires are color coded for correct and easy installation. Laser Iridium Spark Plugs provide superior ignitability and long service life. Smallest tip diameter available iridium/platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions. Laser welded Iridium center electrode tip ensures high durability and greater spark. Platinum disc welded to backside of ground electrode provides long life. Longer insulator nose prevents fouling, corrugated ribs on insulator prevents flashover, and the triple gasket seal eliminates combustion gas leakage. Faster starts and quicker acceleration. Better fuel economy and lower emissions, trivalent metal plating for superior anti-corrosion and anti-seizing.
