product details


ACCEL 5mm 300 Ferro-Spiral Race wire sets put their race-winning wire core into a much smaller spark plug wire with only a 5mm jacket. This is the same maximum-energy core found in the other 300 Race wires, just in a smaller package. ACCEL 5mm 300 Ferro-Spiral Race wire sets reduce weight, which is critical on a race car, and they are easy to hide on a street rod with a custom-look engine compartment. ACCEL 5mm 300 Ferro-Spiral Race wire sets can be routed in and around places where larger wires simply cannot go, for the ultimate in good looks and custom-fit possibilities. You can hide them if you like, but they're available in great looking colors to show off, too! They're available with 90 degree plug boots to keep the spark plug wires routed as close to the engine as possible.
