Description Reviews Magnacor Spark Plug Wires come in 8.5mm (Red) or 8mm (Blue) and will work on Gen 1 Cooper or Cooper S's. They will give your electrical system a bump in performance to complement all your other performance mods, or are a good replacement to replace your worn out stock ones. There is not much of a difference in performance between the 8.5mm (Red) or 8mm (Blue), so pick the color that best complements your engine bay's color scheme. Red 8.5mm Magnecor's KV85 Competition (8.5mm)Ignition Cables feature Magnecor's exclusive 2.5mm high capacity Metallic Inductance EMI Suppressed conductor consisting of stainless steel wire precisely wound at 200 turns per inch over a ferrimagnetic core. The insulating jacket is made entirely of Magnecor's exclusive TC-1500-HS high strength aerospace grade silicone rubber, and its single layer construction will prolong the jacket's insulating ability by conducting extreme heat away from hot-spots that occur near over-the-limit heat sources. The KV85 8.5mm jacket has a service heat resistance of 600 degrees F (320 degrees C) and up to 1,000 degrees F (540 degrees C) for short burst 3 minutes. Even if limits are exceeded, the silicone rubber will retain its insulating ability until wires are removed from engine. Magnecor Race Wires are primarily designed and constructed to be used in applications where it is essential to prevent the possibility of ignition wires compromising engine performance. Modern race engines, modified street engines and stock street engines which rely on electronic devices to control the function of either or both the ignition and fuel systems are prone to interference from all other spiral conductor ignition wires sold through performance parts outlets, none of which can provide proper suppression for EMI, particularly if a high-output ignition system is used.Magnecor always recommends the use of Race Wires for any stock or modified late model street engine that is electronically managed, however most other modified or street engines can also use Magnecor Race Wires to improve ignition performance. All Magnecor KV85 Competition 8.5mm Plug Wires are Red in color. Blue 8mm Magnecor 8mm Electrosports 80 Ignition Cables are an original equipment replacement. Designed to improve original ignition system performance on street vehicles using either electronic engine management systems or carburetors. Conductor provides excellent RFI and EMI suppression to permanently eliminate the typical performance and fuel-wasting spark energy deterioration of OE and aftermarket carbon conductor wires. Also overcomes performance problems associated with poorly suppressed aftermarket spiral conductor wires on both modern and older engines. The conventional style insulating jacket consists of high dielectric strength silicone rubber insulation, fiberglass reinforcing braiding and a high temperature, high tear strength silicone rubber outer jacket. The flexibility and ruggedness of the cable allows it to be fitted into original 7mm cable holders. Ideal for use on heat-generating LPG (propane) gas conversion engines.Magnecor ELECTROSPORTS Series Ignition Cables are intended for use as factory replacement wires on both the most recent engines with computerized management systems and older engines with carburetors and/or mechanical fuel injection. All Magnecor Electrosport 80 Series 8mm Plug Wires are Blue in color. 1 Review 5 Nice clean wires Posted by Joe on 29th Mar 2015 These wires are extremely flexible, feel very solid and perform as they should. They are very short and clean under the bonnet, no excess length to have to route around. As we all know, Red = Racecar! Solid upgrade from stock wires.
