Racing Beat''s ULTRA 8mm wire sets for street-application 1971-1985 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.
We offer ULTRA Ignition Wire sets for both street and race applications. Street wire sets combine excellent radio noise suppression with high performance (5k Ohm,- 6k Ohm) while the race provides lower resistance (0k Ohm,- 1k Ohm), with substantial radio interference.
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.
