The 4-Piece HS Extension Lead Set (PP400) is an accessory kit designed to perform accurate secondary ignition measurements on vehicles equipped with single-coil-on-plug systems. These extension leads are installed between the spark plug and the coil, giving technicians easy access to the ignition signal for diagnostic purposes.
 Key Features:
 Easy installation: The HS extension leads are placed between the spark plug and the single spark coil, allowing direct access to the ignition signal without the need for major disassembly.
 Compatibility: Specifically designed for use with the MI074 secondary ignition pickup cord, but also suitable for other measurement systems capable of displaying ignition patterns.
 Set of four: The set contains four extension cords, which makes it possible to test multiple cylinders simultaneously and thus work more efficiently.
 Application:
 The HS extension leads are ideal for measuring and analyzing secondary ignition signals in vehicles with single spark ignition coils. By using the extension leads in conjunction with an oscilloscope and a secondary ignition probe, technicians can evaluate the performance of the ignition system and identify any problems.
