LIDSCURA Ignition Coil Kit with Spark Plugs — 2-Piece Replacement for Kohler CH/CV/SV Engines, Restores Starting

The LIDSCURA 24 584 45-S ignition coil kit is a two-piece replacement set that includes two coils and two K7TC spark plugs designed to restore reliable spark for compatible Kohler CH, CV and SV small engines.

If your lawn mower or small engine is misfiring, hard to start, or has weak performance, a worn ignition coil or fouled spark plug is often the culprit. This LIDSCURA replacement kit matches multiple Kohler part numbers and engine families so you can swap both coils and plugs in one service visit. The kit is built to fit a wide range of Kohler CH, CV and SV series engines used on walk-behind mowers, zero-turns and other outdoor power equipment.

How do I install these ignition coils and spark plugs?

Installation is straightforward for anyone comfortable performing basic engine maintenance. Remove the engine shroud, disconnect the old coils and plug wires, swap in the new coils and plug, then reassemble in reverse order. Always disconnect the battery or spark lead before working and follow your mower’s service manual for torque specs.

• Tools needed: socket set, torque wrench, screwdriver, feeler gauge if setting gap.
• Torque: follow Kohler’s recommended coil and spark plug torque values in the manual.
• Safety: disconnect spark and wear eye protection; ensure engine is cool.
• Tip: replace both coils together for balanced performance and longevity.

What performance changes should I expect after replacing them?

Replacing a failed coil and a worn plug typically restores consistent ignition timing and stronger combustion, which helps with start-up and throttle response. You may notice quicker cranking, fewer misfires under load, and steadier idle once the new parts are installed and gapped correctly.

• Improved starting and reduced backfiring or misfires.
• Smoother idling and more reliable rev response under load.
• Balanced firing when both coils are replaced as a matched pair.
• Includes K7TC spark plugs to ensure correct electrode type and heat range.
