About the NGK DIS Ignition Coil Product Line

The NGK DIS Ignition Coil line is tailored for distributorless ignition systems, providing reliable spark delivery without the need for a traditional distributor. This product line focuses on durability and compatibility with modern ignition setups, such as those found in Subaru Forester, Impreza, and Legacy models. The NGK DIS Ignition Coil 48587 is part of this line, ensuring it meets the specific electrical and mechanical requirements of these vehicles.

Product Details and Compatibility

This ignition coil operates at 12 volts and is designed specifically for distributorless ignition systems, which are common in Subaru Forester, Impreza, and Legacy vehicles. The coil type is DIS, meaning it is intended for direct ignition setups that eliminate the distributor cap and rotor. The coil is not oil filled, which is typical for many modern ignition coils, relying instead on solid-state insulation. It features blade-type terminals with three connections, including a female connector and male terminals, ensuring proper electrical connections within the ignition system. Note that this coil does not include a mounting bracket, so it is designed to fit into existing mounting points on compatible Subaru models.

Common Applications and Issues Addressed

• Replacement for faulty or worn ignition coils in Subaru Forester, Impreza, and Legacy
• Resolves engine misfires caused by weak or inconsistent spark
• Improves starting reliability in distributorless ignition systems
• Addresses rough idling and poor acceleration linked to ignition coil failure
• Helps restore proper ignition timing and combustion efficiency

Installation Notes and Tips

When installing the NGK DIS Ignition Coil 48587, ensure the vehicle’s ignition system is compatible with distributorless ignition coils. Verify the blade terminal connections match the vehicle’s wiring harness, noting the female connector and male terminal configuration. Since no mounting bracket is included, use the existing bracket or mounting points on the vehicle. It is recommended to disconnect the battery before installation to prevent electrical shorts. After installation, check for secure electrical connections and test the ignition system for proper operation.
