BDFHYK Ignition Coil and Spark Plug Kit UF603 + 97390 for Honda Accord 2008-2012 — Direct-Fit, Iridium Plug

BDFHYK Ignition Coil UF603 paired with Spark Plug 97390 is a direct-fit replacement kit designed to restore reliable ignition performance for compatible Honda and Acura models.

When an aging ignition coil or spark plug causes rough idle, hard starts, or poor throttle response, replacing both components with matched parts can bring back smooth running and consistent spark delivery. This kit bundles a UF603-design ignition coil and an iridium-equipped 97390 spark plug engineered to meet fitment and durability expectations for select Honda Accord, Pilot, Ridgeline, Odyssey, Crosstour and several Acura vehicles. Always confirm OE cross-reference numbers and vehicle compatibility before purchase.

How will this coil and plug pair affect starting and idle?

Replacing worn coils and plugs improves ignition reliability so the engine fires consistently on each cylinder, reducing misfires and rough idling. Better spark stability often shortens cranking time and smooths low-RPM operation.

• Direct-fit UF603 coil design for original mounting and electrical connection
• Iridium tip plug (97390) for a persistent, stable spark
• Reduced misfire risk and steadier idle after installation

What materials and construction features matter for longevity?

This BDFHYK coil uses robust silicon-steel cores, varnished copper winding, and high-grade rubber insulation to resist heat and vibration. The spark plug combines a durable ceramic body with an iridium electrode to resist erosion and maintain a narrow gap over many miles.

• Silicon steel and varnished wire for improved coil thermal stability
• Imported rubber seals to limit moisture ingress and cracking
• Iridium electrode spark plug for long service life and consistent gap retention

Which cars are compatible and how do I confirm fitment?

The kit lists fitment for many late-2000s and early-2010s Honda and Acura models, including Accord (2008–2012) and Pilot (2009–2015). Before buying, match the OE reference numbers and compare the connector and mounting style with your existing parts.

• Common compatible models: Honda Accord, Odyssey, Pilot, Ridgeline, Crosstour; Acura TL, RL, RDX, TSX, ZDX
• Cross-check OE codes such as UF603, UF624, UF-60330520-RN0-A01 and 97390/LKR7BGPS
• Verify physical connector and boot shape against your current coil pack

Is this an easy DIY replacement or should a shop do it?

Installation is straightforward for anyone comfortable with basic engine-bay work: remove the engine cover, unplug the coil, unbolt and swap the coil, then replace plugs if included. Torque specs and gap checks matter—refer to factory specs or the included manual; if unsure, a professional installation avoids damage.

• Includes coil installation guidance; check torque and plug gap
• Requires basic hand tools and common safety precautions
• Professional install recommended when access or diagnostic tools are needed

Who is this for: The BDFHYK UF603 ignition coil and 97390 spark plug kit is aimed at owners of compatible Honda and Acura vehicles who are experiencing ignition-related symptoms or performing routine maintenance around 80,000 km and beyond. It suits DIYers wanting a direct-fit replacement with upgraded plug materials, and technicians seeking a matched coil-and-plug option for repair or tune-up work. Confirm part cross-references and vehicle fitment before ordering to ensure correct compatibility.
