BDFHYK Ignition Coil & Iridium Spark Plug Kit UF596 + 93501 for Toyota Corolla 2009–2017 — OE-fit, Durable Performance

BDFHYK Ignition Coil UF596 paired with Spark Plug 93501 is a direct-fit ignition kit designed to restore consistent spark and reliable starts for compatible Toyota, Lexus, Prius V and Scion models.

This kit bundles a replacement ignition coil (UF596) and an iridium spark plug (93501) engineered as OE-alike parts for a range of Toyota-platform vehicles from late 2000s to the late 2010s. Built with higher-grade materials—varnished wire, silicon-steel core and iridium electrode—the components aim to deliver durable electrical performance and predictable combustion compared with worn factory parts. Always confirm OE numbers and vehicle fitment before purchase to ensure compatibility.

Which vehicles will this ignition coil and spark plug fit?

The BDFHYK UF596 coil and 93501 spark plug cover many Toyota platform models. Fitment includes Toyota Corolla (2009–2017), Prius (2010–2015), Matrix (2009–2014), Prius V (2012–2017), C-HR (2018–2020), plus Lexus CT200h (2011–2017) and select Scion models. Use your vehicle’s year, engine code and original equipment numbers to verify match.

• Compatible OE references: UF596, UF-596, UF619, C1714 and others listed on the product details.
• Spark plug OE reference: LKAR7BIX-11S / 93501—confirm against your parts sticker or service manual.
• Not universal—check pictures or vehicle compatibility table on the product page.

How do these parts improve starting and drivability?

Replacing a degraded coil and spark plug can reduce misfires, improve throttle response and make cold starts crisper. The UF596 coil uses quality winding and rubber materials to maintain stable high-voltage delivery, while the iridium 93501 plug helps sustain a reliable spark longer than standard electrodes.

• Stronger, consistent spark reduces hesitation and rough idling.
• Iridium tip resists erosion for longer service life and steady combustion.
• Proper coil insulation lowers the chance of voltage leakage and misfires.

What are the construction and quality highlights of the kit?

BDFHYK specifies materials intended to extend component life compared with low-cost replacements. The coil assembly uses silicon steel cores, imported varnished wire, and durable rubber parts; the spark plug features a fine iridium electrode and robust ceramic body. These choices focus on heat endurance and electrical reliability rather than cosmetic differences.

• Coil: silicon-steel core, high-temperature rubber and varnished copper windings.
• Spark plug: iridium electrode and high-quality ceramic insulator for consistent gaps.
• Manufactured by a supplier with automotive lines and over 10 years’ experience in parts production.

When should I replace these parts and what symptoms indicate failure?

Consider replacement if your vehicle has over ~80,000 km or shows running issues. Common symptoms include engine shaking, slow acceleration, increased fuel consumption, or difficulty starting. Replacing coils and plugs together helps restore ignition timing and combustion efficiency more completely than changing one component alone.

• Engine misfires or rough idle under load or at startup.
• Poor fuel economy and sluggish throttle response.
• Intermittent start failures or check-engine codes related to ignition misfire.

Who is this for: The BDFHYK UF596 + 93501 kit is aimed at DIY mechanics and professional technicians servicing Toyota, Lexus or Scion vehicles listed in the compatibility section who want an OE-style replacement. It’s suitable for owners restoring performance after significant mileage, or anyone addressing ignition-related drivability problems. Always verify your original equipment numbers and vehicle fitment before ordering to ensure proper installation and function.
