UF583 Ignition Coil Pack and 9807B-561BW Spark Plugs Set of 4

In this review of the UF583 ignition coil pack and 9807B-561BW spark plugs set, the bottom line is simple: this kit is aimed at owners of compatible Acura and Honda 2.0L and 2.4L L4 models who need an affordable, practical ignition repair that usually fixes misfires and rough idling. The reviewer found the set delivers dependable ignition performance when fitment is correct, combining robust coil construction and fine iridium plug electrodes to restore stable starting and smoother acceleration without a large expense.

Key Features

• Multivehicle compatibility: The kit fits a range of Acura and Honda 2.0L and 2.4L L4 models, making it useful for DIYers who work on several vehicles.
• Premium coil materials: Coils use silicon steel, a high-pressure rubber sleeve and imported epoxy resin for improved durability and resistance to cracking.
• High-performance spark plugs: Iridium electrodes and CNC-machined metal parts promote reliable ignition, quicker starts and smoother throttle response.
• OE-equivalent fit and function: Coils and plugs are made to meet or exceed OE specifications for form, fit and function for straightforward replacement.
• Quality control testing: Each coil and plug is tested to ensure stable high-voltage output under operating conditions, addressing common faults like misfiring or rough idle.
• Complete kit: Package includes four ignition coils, four spark plugs and a manual, so owners get everything needed for a four-cylinder engine swap.

Who It's For

This kit is best for owners of Acura RSX (2002-2006 2.0L) and Honda Accord, Civic, CR-V and Element models listed for 2.0L and 2.4L L4 engines who suspect ignition coils or spark plugs are causing misfires, poor fuel economy or rough idling. DIY mechanics who prefer to replace all coils and plugs at once to reset ignition performance will appreciate the convenience.

Those who should look elsewhere include owners whose exact vehicle year or engine variant is not in the fit list, or anyone who requires dealer-original branded parts for warranty or OEM traceability. Always confirm fitment against the vehicle picture or detail page before purchasing to avoid compatibility issues.
