The Racing Beat ULTRA 7mm Red Hot Ignition Wire Sets for the 2001-2005 Miata and the 2001-2003 2.0 L Protege utilize silicone rubber for both the 7mm wire insulation and boots, with a minimum rating of 100,000 volts in all areas. The silicone rubber is designed to withstand continuous temperatures ranging from -60 degrees F to +480 degrees F. Brass "screw-together" connectors are double-crimped onto the zinc-clad, stranded copper wire ends to provide absolute contact with no possibility of deterioration. The silicone boots seal watertight at the spark plugs and ignition coil for added protection. A unique design feature seals a wire wound resistor inside the spark plug terminal to optimize noise suppression and power.

With the release of the 2001 Miata and the 2001 Protege, Mazda incorporated "igniter" units into the ignition system design. The use of these igniters eliminates the need for a traditional 4-wire spark plug wire replacement set. This new design positions an igniter above one spark plug, with a traditional plug wire connecting the short distance to an adjacent spark plug. There are two igniters, and two wires in this arrangement.

So why offer a spark plug wire replacement set for two very short wires? Our initial research found that there were significant resistance differences between these stock wires. We fabricated a set of ULTRA wires and installed them on a special project Miata that we were working on. While undertaking a series of dyno tests during a header test session, we conducted some back-to-back testing with the ULTRA and stock wires and noticed a very slight .5-1 HP gain with the ULTRA wires. Now these aren''t the most pavement shaking gains we''ve ever measured, but they were gains nonetheless!

To obtain maximum horsepower gains, while curbing radio interference from your ignition system, we recommend the use of resistor spark plugs with our ULTRA 7mm Street Ignition Wires.
