BDFHYK Ignition Coil & Iridium Spark Plug Kit, Set of 6 for Honda/Acura V6 3.5L-3.7L — Direct-Fit

BDFHYK’s set combines six UF603 ignition coils with six 97390 iridium spark plugs engineered to restore reliable ignition for Honda and Acura V6 engines (3.5L / 3.7L). These replacement coil packs and iridium spark plugs are designed for direct-fit service on many Honda and Acura models from the late 2000s to mid-2010s. Built with high-grade materials — including silicon steel cores, imported rubber boots, varnished windings, and a fine iridium electrode — this kit aims to return consistent spark, smoother idle, and improved throttle response when original components show wear. Always verify OE part numbers before purchasing to confirm compatibility with your exact model and year.

Which vehicles and engines will these parts fit?

The BDFHYK UF603 coils and 97390 spark plugs suit a range of Honda and Acura V6 models. Coverage includes many 3.5L and 3.7L engines used in mid-2008 through mid-2015 model years, but fitment varies by VIN and engine code.

• Honda Accord (2008–2012), Crosstour (2010–2012), Odyssey (2011–2017)
• Honda Pilot (2009–2015), Ridgeline (2009–2014)
• Acura TL, RL, TSX, RDX, ZDX (various 2009–2015 models)
• Check OE references: UF603, UF624, 97390, LKR7BGPS and original coil numbers before ordering

How do these ignition coils improve engine performance?

Upgraded coil packs restore a strong, focused spark to each cylinder, which helps combustion stability and throttle response. The manufacturing materials — silicon steel core and varnished wire — reduce magnetic losses and heat-related degradation for longer life compared with cheap replacements.

• More consistent spark reduces misfires and rough idling
• Stable ignition under load improves acceleration and drivability
• Durable construction resists cracking and electrical leakage

Why choose iridium spark plugs (97390) over standard plugs?

Iridium plugs use a fine-tipped electrode that requires less voltage to create a reliable spark and resists electrode wear far longer than conventional plugs. That translates to easier cold starts, steadier combustion, and longer service intervals when the plugs are properly installed.

• Iridium tip provides consistent spark energy and longevity
• High-grade ceramic insulator resists fouling and heat stress
• Helps maintain fuel efficiency and ignition reliability over time

What should I check before installing this kit?

Confirm the OE part numbers and physical fit before installing: coil reference UF603/UF624 and spark plug 97390 (LKR7BGPS). Inspect surrounding wiring, connectors, and ignition harness for damage; replacing old coils and plugs on worn wiring can reveal other service needs.

• Match OEM numbers and compare mounting points and electrical plugs
• Inspect spark plug gap and torque to manufacturer specifications
• Replace or clean ignition harness connectors if corroded or brittle

Who is this for? This BDFHYK ignition coil and iridium spark plug set is aimed at owners and technicians servicing V6 Honda and Acura models who want a direct-fit replacement with improved materials and longevity. It’s suitable for vehicles showing symptoms of aged ignition parts — intermittent misfires, rough idle, slower throttle response, or higher fuel use — and for anyone wanting to refresh the ignition system during routine major service intervals. Remember to verify exact fitment for your VIN and engine variant before purchasing to ensure a correct, plug-and-play installation.

FAQ

Q: Are these coils and plugs a direct fit for my Accord V6?

A: Possibly—confirm your VIN’s OE numbers (UF603/UF624 and 97390) against the listing to ensure direct fitment.

Q: How often should I replace these spark plugs and coils?

A: Iridium plugs typically last longer than standard plugs; inspect coils and plugs every 60–100k km or if misfires occur.
