Please note that recent unbiassed comparisons of ignition wire resistance in relation to engine power and torque output shows there to be little or no relationship or correlation to the long accepted assumption that lower resistance in a wire translates to higher power output. Reference Circle Track Magazine, May 1996, P. 48-54.Please also note that some of these wires may emit electrical interference which may cause problems with newer computer controlled vehicles, especially those with performance modifications and aftermarket amplified stereo systems. Specifically the Nology Hotwires Race. Also note that the Magnecor 8.5mm competition is designed to offer enhanced noise suppression over their already suppressed 8mm wire. These considerations may or may not be concerns for your particular situation, consult the manufacturer for assistance.
