Two genuine Kohler 12mm RFI spark plugs sold as a pack, engineered for reliable ignition and to reduce radio-frequency interference in compatible small engines.

This pair of Kohler spark plugs (part number 14 132 11-S) is an OEM replacement designed for small engines that call for a 12mm, radio-frequency interference (RFI) style plug. Supplied as a two-pack, they simplify maintenance by letting you replace both plugs at once when required. These plugs are built to fit specified Kohler engines without modification and match factory electrical and physical specifications to maintain consistent performance.

Which engines or models will these plugs fit?

They are intended for Kohler engines and applications that require a 12mm RFI spark plug and specifically list part 14 132 11-S in the parts manual. Always check your engine’s service manual or parts diagram for compatibility before ordering to ensure proper thread size and reach.

  • 12mm thread diameter compatible with engines requiring that size
  • Listed as OEM Kohler part 14 132 11-S in Kohler parts catalogs
  • Best-suited to engines specifying RFI suppression plugs
  • Sold as a two-piece set for dual-cylinder or paired maintenance

How do these RFI plugs affect electronics and ignition?

RFI spark plugs are designed to minimize radio-frequency noise produced by ignition events, which can help reduce interference with nearby electronic systems like radios, GPS, or engine sensors. They don’t change ignition timing; instead, they help contain electrical noise while providing the spark necessary for combustion.

  • RFI construction reduces electromagnetic interference in the engine bay
  • Maintains consistent spark energy for normal ignition function
  • Compatible with equipment where interference-sensitive electronics are present

What should I know about installation and maintenance?

Installation is straightforward for anyone comfortable with basic engine maintenance: remove the old plugs, check gap if required, and torque the new plugs to the engine manufacturer’s specification. Using a torque wrench and the correct socket prevents damage to the cylinder head and ensures a proper seal.

  • Verify plug gap if your engine manual specifies a gap measurement
  • Hand-start threads, then torque to Kohler’s recommended specification
  • Replace in pairs when convenient to keep ignition performance even
  • Inspect plug condition periodically for wear, deposits, or fouling

Why choose the genuine Kohler OEM option instead of aftermarket plugs?

OEM Kohler parts are produced to the original factory specifications, providing consistent fit and known electrical characteristics that match the engine’s design. Choosing the genuine part reduces the risk of compatibility issues and simplifies warranty and parts-identification tasks.

  • Manufactured to Kohler factory specifications for fit and function
  • Guaranteed thread size and reach for intended engines
  • Same electrical suppression characteristics as factory-installed plugs
  • Sold as a convenient two-pack for streamlined maintenance

Who is this for: This two-pack of Kohler 14 132 11-S 12mm RFI spark plugs is aimed at owners, technicians, and fleet managers maintaining Kohler-powered equipment that specifies this OEM part. If you need a direct-fit replacement with RFI suppression and the assurance of factory-matched dimensions, this pack is a practical maintenance item for lawn tractors, generators, or other compatible small engines.
