Hyundai Ignition Coil 27301-3E400 DQ9101E for 4-Cylinder Engine Applications

This product is an ignition coil supplied with the manufacturer reference 27301-3E400 (also listed as 273013E400). It is a direct-fit replacement component designed specifically for certain 4-cylinder Hyundai engine configurations. The coil matches the DQ9101E model specification, indicating it is engineered to provide the correct electrical characteristics required by the vehicle's ignition system. Supplied as a single unit in its original packaging, this part aims to offer a straightforward solution when replacing a failed or ageing ignition coil on compatible models.

Features and Construction

This ignition coil is built to the specifications of the DQ9101E type. Its core function is to transform the vehicle's low-voltage battery current into the high-voltage pulse needed to create a spark at the spark plug.

Material and Build

The internal construction follows standard ignition coil design, utilising primary and secondary copper windings around a laminated steel core. This assembly is housed within a casing made from high-temperature resistant plastic or epoxy, which provides electrical insulation and protection from engine bay heat and vibration. The external finish is black.

Size and Practical Fit

The physical dimensions and electrical connector configuration are designed to match the original 27301-3E400 part. This ensures it fits into the designated mounting location on the engine and connects directly to the vehicle's wiring harness without the need for adapters or modification, facilitating a simpler installation process for the correct vehicle applications.

Uses and Placement

This part is intended solely as a service replacement item for the ignition system of specific Hyundai vehicles with 4-cylinder engines.

Event or Professional Use

For professional mechanics or workshops, this coil provides a specified OEM-numbered part for repair jobs where diagnostic tests have confirmed a faulty ignition coil is the cause of misfires, poor starting, reduced fuel efficiency, or a check engine light related to ignition circuit faults on supported Hyundai models.

Everyday Home Use

For the knowledgeable DIY mechanic working on their own compatible Hyundai vehicle, this direct-fit part allows for the replacement of a worn ignition coil. Correct installation can help restore smooth engine idle, consistent acceleration, and reliable starting performance.

Benefits and Buying Value

The primary value lies in obtaining a component that corresponds to a specific, often hard-to-source, original equipment part number.

Reuse and Low Maintenance

An ignition coil is not a serviceable or reusable item once it has failed. The value here is in the correct initial fitment, which, if the underlying ignition issue is resolved, should return the system to standard operation without requiring immediate further attention, assuming all other ignition components are in good condition.

Why Choose This Product

Choosing this product is based on the confirmed need for the exact 27301-3E400 / DQ9101E ignition coil on a specific 4-cylinder Hyundai vehicle. Its value is its specification match, which aims to ensure compatibility and correct electrical performance, avoiding the potential issues of mismatched or universal-fit parts.
