Spark Plug Wire is one of the vital components of the Toyota 4Runner vehicles since it is involved in the ignition process through transferring electricity from the ignition coil to the spark plugs. Other names for these cables include high tension leads or HT leads and they are manufactured with an insulating material that can stand heat so as to eliminate chances of arcing and are highly durable. Hoses of spark plugs have correct cuts and come with metallic endings to allow grounding. The radio frequency interference that is usually conditioned in houses is minimized through the use of modern technologies while the high-quality wires have brass terminals to minimize the effects of corrosion. Despite the fact that the engines of early years had a coil wire, engines of the contemporary years have coil packs or multiple ignition coils placed right on spark plugs, thus, there are no spark plug wires any longer. Maintenance and positions of those cables are critical to the correct running and long life of the engine used in vehicles.
