Thank you. You have rated this product.

Racing Beat's ULTRA 8mm wire sets, with noise suppression shields, for street-application 1971-85 12A and 13B engines are constructed with zinc-plated high-strength copper wire to prevent corrosion. Threaded brass connectors are crimped to all wire ends to provide a superior connection. The silicone rubber used will handle over 100,000 volts and is capable of withstanding temperature ranges from -60 F to +480 F over exceptionally long periods. ULTRA Ignition wire sets have a wire wound resistor encapsulated in each spark plug boot. This feature reduces electromagnetic radiation.

To obtain reasonable horsepower gains while curbing radio interference from your ignition system, we recommend the use of resistor spark plugs with our ULTRA 8mm Street Ignition Wires. To obtain maximum power gains from our ULTRA 8mm Race Ignition Wires, we recommend the use of non-resistor spark plugs.

Each wire set is assembled "in-house" by our Racing Beat technicians using the high quality ULTRA ignition components. Produced in Japan, these components are hand-assembled for each specific application that we offer. Each set is assembled and test to ensure correct resistance prior to final packaging. This custom assembly process provides us with complete control over the entire assembly procedure.

You guys are great! The new suspension is in and the ride is much improved. Thanks for the great service.

I red'all the parts in the order I placed and installed them in my car yesterday. I am beyond happy. The install went without a hitch. The results were fantastic. The new brakes track straight, make no noise, and stop the car authoritatively. The new rotors look pretty cool, which we all know isn't all that important, but having 6 women offer to bear your children, because your car looks SO cool is a good problem to have. Thank for great products and service.
