BDFHYK Ignition Coil and Iridium Spark Plug Kit UF596 + 93501 — Toyota Corolla 2009-2017 Fit, Improved Ignition

High-quality ignition coil UF596 paired with iridium spark plug 93501 — a direct-fit replacement for many Toyota and Lexus models from late 2000s to 2010s designed to restore reliable ignition and smoother starts.

This BDFHYK kit bundles a replacement ignition coil (UF596 series) and an iridium spark plug (93501) engineered to fit a range of Toyota, Lexus and Scion vehicles. Built using robust materials—silicon steel cores, imported rubber seals, and varnished windings—the coil packs are made for extended service life. The spark plug uses an iridium electrode and durable ceramic to maintain consistent firing and improved throttle response compared with worn components. Always confirm OE part numbers and vehicle fitment before ordering.

Which vehicles and OE numbers does this kit fit?

The kit is compatible with many Toyota, Lexus and Scion models from approximately 2008–2020, including Corolla, Prius variants, Matrix, C-HR, CT200h and selected Scion models. Fitment depends on engine and production year, so cross-check against your VIN or original part numbers.

• Common OE references to verify: UF596, UF-596, UF619, C1714 and 90919-02252 / 90919-02258.
• Spark plug OE references: LKAR7BIX-11S and 93501 series.
• Compatible models include Toyota Corolla (2009–2017), Prius (2010–2015), Prius V (2012–2017), Matrix (2009–2014), C-HR (2018–2020), Lexus CT200h (2011–2017), Scion xD (2008–2014), Scion iM (2016).

How will replacing both the coil and spark plug affect everyday driving?

Installing a matched coil and iridium plug set helps restore consistent ignition energy, which can improve start-up reliability and throttle response when old components have degraded. You should notice smoother idling and fewer misfires if ignition parts were the source of issues.

• Smoother engine starts and reduced hesitation under acceleration.
• Fewer misfires and more stable idle at low RPMs.
• Iridium plug maintains a strong spark longer than conventional plugs.

What are the construction and material benefits of the BDFHYK coil and spark plug?

BDFHYK uses a mix of industrial-grade materials to extend component lifespan and stability under heat and vibration. The coil windings are varnished for insulation, sealing uses imported rubber, and the spark plug employs an iridium tip for durable firing performance.

• Coil: silicon steel core, varnished wire for heat resistance, high-quality rubber seals.
• Spark plug: iridium electrode and engineered ceramic for long-term sparking.
• Manufactured under an established supplier network with factory-level quality control.

When should I replace my ignition coils and spark plugs?

If your vehicle has over ~80,000 km or shows signs like rough idle, slow acceleration, or difficulty starting, it’s a good time to inspect ignition components. Replacing both coil and plug as a matched set prevents compensating faults and provides more reliable performance.

• Replace after extended mileage or when experiencing misfires and poor acceleration.
• Swap both coil and plug together for consistent ignition characteristics.
• Always verify OE part numbers before installation to ensure proper fit.

Who is this for: This BDFHYK UF596 + 93501 kit is aimed at DIY enthusiasts, independent garages and owners of compatible Toyota/Lexus/Scion vehicles who want an affordable, factory-style ignition repair. It suits drivers seeking a long-lasting coil and an iridium spark plug to restore dependable starts, smoother running and reliable ignition without replacing unrelated systems.
