Magnecor replaces its 7mm HIGH PERFORMANCE IGNITION CABLE with ELECTROSPORTS 70 IGNITION CABLE Technical Bulletin 060001 Commencing 2000 For over 20 years Magnecor manufactured ignition leads using its 7mm HIGH PERFORMANCE IGNITION CABLE. Lead sets using this cable were very popular as a superior replacement for 7mm size original equipment and aftermarket ignition leads using limited-life carbon conductors and resistor/connectors at lead ends. Over the years, the wire-wound conductor was updated to provide better RFI suppression, and later versions achieved moderate EMI suppression. A small 7mm insulating jacket makes providing a wirewound conductor to properly suppress EMI (needed by late model engines) both difficult and expensive. To suppress EMI, most manufacturers use leads with carbon conductors and resistor/connectors at lead ends. Although these leads deteriorate with use and spark current is reduced, manufacturers are not concerned, because they all treat ignition leads as service items to be replaced regularly. Others in the aftermarket use cheap wire-wound conductors that cannot properly suppress EMI (no mention is ever made of this fact). In the past, it has been a policy at Magnecor to recommend our 8.5mm KV85 COMPETITION CABLE sets (designed primarily for race engines) if we thought a possible EMI problem could arise on later model engines fitted with 7mm leads as original equipment. Of course, not all vehicle owners necessarily want to purchase more expensive larger diameter ignition leads designed for a race engine. All they want is good ignition leads with a conductor providing proper suppression that wont deteriorate with usage more so, with so many late model multi-valve engines using ignition leads (fitted with complicated extended spark plug connectors) that have become very expensive and time consuming to replace. 42 The good news is, with the recent introduction of our ELECTROSPORTS 70 IGNITION CABLE, we can now offer a 7mm ignition cable with a wire-wound conductor to properly suppress both RFI and EMI. Lead sets using ELECTROSPORTS 70 IGNITION CABLE can be used on both older and newer carburetted engines and the most modern fuel injected engines using any electronic engine management system. Excellent suppression is also provided for 2-way radio equipment. In addition, a new insulating jacket provides better insulation than most 8mm original equipment and aftermarket leads, and new construction provides better terminal retention than ever before. Remaining Limitation When used with either the original ignition system or a better ignition system designed for street use, lead sets using our ELECTROSPORTS 70 IGNITION CABLE will prove to be vastly superior to all limited-life 7mm original equipment and aftermarket carbon conductor leads, resistor/connector leads and other brand wire-wound conductor leads. However, no 7mm or 8mm cable size leads can fully insulate the maximum output from a racing ignition system.
