Set of 6 UF242 Ignition Coil Pack and 4503 Spark Plugs Compatible

In this review the Set of 6 UF242 ignition coil packs and 4503 spark plugs is presented as a direct-replacement kit aimed at owners of compatible Acura and Honda V6 models who need to resolve ignition faults. The bottom line: this kit is for drivers who want an affordable, full-bank replacement that addresses common problems like misfires, rough idle and poor fuel economy. The reviewer found the components to be well engineered for replacement use and noted the clear value of receiving six coils and six plugs in one package.

Key Features

• Multivehicle compatibility: The kit fits Acura CL 2001-2003 and TL 1999-2003 plus Honda Accord 2000-2002 and Odyssey 1999-2007, which simplifies sourcing parts for these V6 models.
• Durable coil materials: Coil packs are built with silicon steel, a high-pressure rubber sleeve and imported epoxy resin to resist cracking and short-circuiting under heat and vibration.
• High-performance spark plugs: The spark plugs use fine iridium electrodes and isostatic ceramic insulators for consistent ignition and reduced wear compared with standard plugs.
• OE-equivalent fit and numbers: Coils and plugs are presented to match common OE references so installers can expect correct form, fit and function for compatible engines.
• Complete bank replacement: The package includes six ignition coils and six spark plugs plus a manual, enabling a full-bank service in one purchase.

Who It's For

This kit is best for DIY mechanics and independent shops working on compatible Acura and Honda V6 models who want to replace an entire bank of coils and plugs at once to cure misfires, rough idle, or check-engine light triggers. It is also a practical option for owners who prefer replacing all ignition components together to avoid repeat labor.

Drivers with nonlisted model years or non-V6 engines should verify fit carefully using the product images and the vehicle application details before ordering. Those seeking OEM branded parts may prefer to source directly from dealer channels if brand-specific warranty or branding is required.

Pros & Cons

Pros
