Don’t subject your engine starter to high temperatures. Keep it cool from the moment you turn it on with high-performing heat shields and insulation. Not only does heat fry your ignition system, but it prevents your vehicle from operating at the optimum level.
Keep your ignition system performing as good as, or better than, the day you bought it, with a heat shield and insulation. Heat shields deflect heat away from your starter, protecting it from it from undesirable temperatures. With a heat shield installed, your vehicle expends less energy cooling itself down and more energy giving you horsepower.
