Thank you. You have rated this product.

Racing Beat s ULTRA 8mm wire sets 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.

NOTE: Some aftermarket performance spark plugs have proven to be unacceptable in terms of manufacturing quality; specifically, these plugs develop compression leaks between the porcelain and steel subcomponents causing both premature spark plug boot failure and genuine horsepower losses. For this reason, we strongly encourage the use of the factory or Racing Beat s recommended spark plugs only for use with our wire sets.

Note: Access to the stock 1993-95 wires is very limited. Installation of these wires requires basic mechanical skills and can be completed by following the supplied step-by-step installation instructions.

Roadstersport II was a great purchase, easy install, and sounds great.

Hi Brian, I just bought a heatshield and a cruise control relocation bracket for my '95 Miata from you. It is in the mail now. Thanks for such fast service. (My cruise is just wrapped up in a microfiber shoprag at this time!)
