TOTEDELL Ignition Coil Module 2-Pack for Kohler KT740 KT745 ZT740 — Includes 2 Spark Plugs, Direct-Fit Digital Magneto

TOTEDELL 2-pack ignition coil modules with spark plugs replace Kohler part 32-584-25-S to restore spark and reliable starts for KT740, KT745 and ZT740 engines.

If your lawn tractor or zero-turn mower is stalling, hard to start, or misfiring, worn or damaged ignition modules are often the cause. These TOTEDELL MAGNETO DIGITAL IGNITION modules are designed as direct-fit replacements for multiple Kohler part numbers (including 32-584-09-S, 32-584-24-S and 32-584-25-S) and are supplied as a 2-pack with two spark plugs. The set targets a broad list of KT740, KT745 and ZT740 variants used across brands like MTD, Husqvarna, Ariens and others, letting you replace both cylinders or keep a spare on hand.

How will these coil modules affect engine starting and idle?

Replacing a failing ignition module can restore a strong, consistent spark, improving cold starts and smoothing idle. The digital magneto design provides stable ignition timing across normal operating RPM ranges, which reduces misfires and hesitation under load.

• Restores spark strength for easier cold starts
• Reduces misfiring and rough idling
• Designed to match factory timing and mounting points
• Includes spark plugs for a complete simple swap

Which machines and part numbers are these compatible with?

The modules are built to replace Kohler part numbers 32-584-09-S, 32-584-24-S and 32-584-25-S and fit many KT740, KT745 and ZT740 engine models. Compatibility spans numerous OEM brands and specific model codes, so confirm your engine part number against the list before ordering.

• Direct replacements for Kohler numbers listed above
• Fits multiple KT740, KT745 and ZT740 variants used by MTD, Husqvarna, Ariens and others
• Sold as a 2-pack to service both coils or keep a backup
• Includes two spark plugs for immediate installation

What comes in the package and what tools are needed to install?

The kit contains two digital magneto ignition modules and two spark plugs so you can replace both coils in a twin setup or swap one now and keep one spare. Installation typically requires basic hand tools and safety precautions: disconnect the battery, remove shrouds, swap the module and plug wires, torque the spark plugs, and reassemble.

• Package: 2 ignition modules + 2 spark plugs
• Commonly required tools: socket set, torque wrench, screwdrivers
• Simple bolt-on replacement for direct-fit models
• Recommended: check gap and torque on supplied spark plugs

How long can I expect these parts to last and how should I maintain them?

Longevity depends on operating conditions, engine maintenance and exposure to heat or vibration. Properly installed modules in regularly serviced engines can give years of reliable operation; follow standard engine care to extend life and inspect electrical connections periodically.

• Service life varies with use and environment
• Keep connections clean and secure to prevent faults
• Avoid excessive heat build-up and physical damage
• Replace spark plugs at recommended intervals for best performance
