Ignition coils are responsible for transforming the battery's low voltage into the high voltage needed to fire the spark plugs. If your engine is misfiring, idling rough, or experiencing poor acceleration, you likely need new coils (like the UF807 or GM D515C). Ignition switches, on the other hand, control the electrical flow to the ignition system (Acc, Off, Run, Start). If your key is sticking, or the vehicle won't crank, a replacement switch is necessary.
Always verify the part number and vehicle compatibility before purchase. Using parts that meet Original Equipment Manufacturer (OEM) specifications, such as the GM Genuine Parts coil, ensures optimal performance and longevity. For specialized vehicles like the Honda Navi or Polaris Ranger, look for direct-fit replacements to guarantee easy installation and correct function.
For V6 and V8 engines, purchasing a complete coil pack and spark plug kit (like the PZ Iridium set) is often the most efficient way to restore peak ignition performance. Since coils and plugs wear out similarly, replacing them together prevents future misfires and ensures balanced performance across all cylinders.
Universal ignition switches are excellent for older vehicles, tractors, or custom applications where a simple 4-position (Acc/Off/IGN/Start) switch is needed. However, modern vehicles with complex security systems (like the Honda Navi) require specific OEM or direct-replacement switches to integrate correctly with the vehicle's electronics.
Common signs include engine misfires (especially under acceleration), rough idling, reduced fuel economy, and the illumination of the Check Engine Light (often with codes related to coil primary/secondary circuit failure).
An ignition coil is a single unit that serves one cylinder. A coil pack is a module that houses multiple coils or a distributorless ignition system that controls the spark for several cylinders, often mounting directly over the spark plugs (Coil-On-Plug design).
Yes. A faulty ignition switch can intermittently lose contact in the 'Run' position, cutting power to the fuel pump or ignition system, causing the engine to stall unexpectedly.
Ensuring your vehicle has reliable ignition components is non-negotiable for smooth operation and dependable starting. From high-output ignition coil packs designed for modern V6 engines to rugged, universal key switches for utility vehicles, our selection provides high-quality solutions for every replacement need.
