Hipa Ignition Coil for Kohler XT/XTX Engines - 14-584-04-S Direct-Fit 6.5-7.75HP with Spark Plug

HIPA 14-584-04-S is a direct-fit replacement ignition coil and spark plug kit designed to restore spark delivery for Kohler small engines (fits models referenced by 1458404S / 14-584-04-S).

If your lawn mower or garden machine with a Kohler XT-series engine is stalling, misfiring, or refusing to start, the fault often traces to the ignition coil. This HIPA coil kit is built to match the electrical and mounting profile of the OE part numbers associated with Kohler 6.5–7.75 HP engines, letting you swap the module quickly and get equipment back into service without a lengthy downtime.

What machines will this ignition coil work with?

The HIPA 14-584-04-S unit is marketed to be compatible with a range of Kohler XT and XTX engines used in mowers and small equipment. It pairs with several part number variations and covers typical 6.5–7.75 hp models.

• Fits Kohler engine lines including XT650, XT675, XT775, XT800, XTX650, XTX675, XTX775.
• Interchangeable with part references 1458404S, 14 584 04-S, and related variants.
• Intended for 149cc series Kohler engines rated around 6.5–7.75 HP.

How easy is installation and what comes in the package?

Installation is straightforward for anyone comfortable accessing the engine flywheel and mounting plate. The kit arrives with the ignition coil and a replacement spark plug so you can complete a basic tune-up in one visit.

• Includes: 1 ignition coil module and 1 spark plug for immediate replacement.
• Mounts with the same bolt pattern as the OE unit, requiring basic hand tools.
• No special programming or additional parts needed for direct swap applications.

Will this ignition coil improve engine performance or reliability?

Replacing a worn or damaged coil restores proper spark timing and intensity, which helps engines idle smoothly and start reliably. While it doesn’t increase engine power beyond factory specs, a good coil reduces misfires and hard-start conditions.

• Delivers consistent high-voltage output to the spark plug under normal operating loads.
• Reduces intermittent starting problems caused by degraded ignition components.
• Helps stabilize idle and throttle response when the rest of the ignition system is in good shape.

Who is this for: This HIPA ignition coil kit is aimed at homeowners, lawn care professionals, and small-engine technicians who maintain Kohler-equipped mowers, tractors, or power equipment. If you have a Kohler XT/XTX series engine showing ignition faults and you need a cost-effective, direct-replacement module plus a spark plug for a quick repair, this kit provides the core components to restore starting reliability and consistent running behavior.
