Top 10 Bosch Spark Plug Guide

Spark plug wires are the heavily insulated wires that carry high voltage from the ignition coil to the spark plug to ignite the fuel air mixture in the cylinder. Thundercore Ultra Wire Sets are made to the highest quality standards. They meet or exceed Original Equipment specifications in regards to fit, form and function. The cable is wire-wound, multi-insulated, and SAEJ2031 Class E rated. The coil on plug boots are made with a high temperature silicone. They also feature premium corrosion-resistant snap lock terminals that click into place for easy installation and removal.

Dependable performance. This Champion spark plug features a copper core electrode that provides increased conductivity and heat control for good overall wear.

These red spark plug wires feature a silicone inner core and outer jacket that keeps the wires flexible while maintaining their color. These wires provide more fire power and up to 10 times less resistance than standard resistor core wires. They eliminate radio frequency interference and are ideal for use with multi-spark discharge ignition systems, electronic ignitions, and on board computer systems. They provide heat protection up to 600-degrees F and come with 180-degree plug boots.

Denso Iridium Spark Plug Iridium plugs have an extremely long life as Iridium is 6x harder and 8x stronger than platinum. Because of the strength and hardness of iridium, there is virtually no electrode wear. This combined with a platinum ground electrode, creates a spark plug that is almost impervious to wear even under extreme driving or racing conditions. Technical Specifications – Extra Long Life Iridium Plug, 14mm Thread, 19mm (3/4″) Reach, 5/8″ (16mm) Hex Size, Gasket Seat, Resistor, Solid Terminal, 0.7mm Fine Wire Iridium-Tipped Center Electrode, Platinum Tipped Ground Electrode, .044″ (1.1mm) Gap

Autolite Copper Core spark plugs deliver quick starts, good fuel economy, and smooth acceleration. The copper-glass seal bonds insulator and terminal post center electrode together to ensure full required voltage at spark gap, creating a gas-tight seal that is 100 percent leak-proof. Copper Core spark plugs feature a cold-formed steel shell and precision rolled threads, and a one-piece terminal post that adds strength. The multi-rib insulator reduces the danger of “flash-over” to prevent misfires, and the resistor reduces radio frequency interference (RFI) and electrode erosion. The full copper core electrode provides better performance in all conditions. Autolite Copper Core plugs are your industry standard.
