BDFHYK Ignition Coil Set for Toyota UF596 Compatible - Set of 4, OE-Fit Heat‑Resistant Coils

BDFHYK's set of four ignition coils (UF596-compatible) replaces worn coil packs on select Toyota, Lexus, Scion and Pontiac 1.8L/2.4L engines to restore reliable spark and smoother running.

This kit contains four replacement ignition coils built to OE-level form, fit and function for multiple Toyota family vehicles and related models. Each coil is manufactured from heat- and chemical-resistant materials, tested under demanding conditions and supplied as a four-pack so you can replace the coils per cylinder to maintain balanced performance. Before ordering, check your vehicle year, engine size and OEM part numbers listed to confirm direct compatibility.

Which vehicles and part numbers does this coil pack replace?

The BDFHYK coils are engineered to fit a range of Toyota and allied models that use the UF596/UF619 family of coil packs. Compatibility covers many Corolla years, Prius generations, Matrix, C-HR, Lexus CT200h, Scion iM/xD and certain Pontiac Vibe models. Always cross-check the OEM number on your original coil against the compatible part numbers provided.

• Common compatible OE numbers: UF596, UF-596, UF619, C1714 and 9091902252/9091902258.
• Fits Toyota Corolla (2009–2017 1.8L; select 2011–2012 2.4L), Prius (2010–2015 plus Prius V 2012–2017).
• Also fits Toyota Matrix (2009–2014), C-HR (2018–2021), Lexus CT200h (2011–2017).
• Compatible with Scion iM (2016), xD (2008–2014) and Pontiac Vibe (2009–2010).

How are these coils built and what materials improve durability?

BDFHYK manufactures these coils to meet OE performance standards with materials chosen for thermal and chemical resistance. The design uses high-grade polymer housings and internal components that resist heat, abrasion and corrosion to extend service life under engine bay conditions. Each coil is subjected to quality-control tests that verify stable high-voltage output.

• Housing materials: Germany-imported PBT and U.S. domestic PPO for heat resistance.
• Manufacturing standard: TS16949-certified production processes.
• Testing: High-voltage stability and extreme-condition endurance checks.

What symptoms might indicate you need to replace the ignition coils?

Faulty coils often produce drivability issues that drivers notice during normal use. Common signs include engine misfires, longer cranking times, loss of power, hesitation during acceleration and reduced fuel efficiency. Replacing all four coils when one fails helps restore consistent firing across cylinders and can prevent further ignition-related problems.

• Engine misfire codes or rough idle under load.
• Extended crank time or difficulty starting the engine.
• Poor fuel economy and noticeable power drop under acceleration.
• Intermittent hesitation or stalling during drive cycles.

How should I install and maintain these coils for best results?

Installation is straightforward for anyone comfortable with basic engine work; coils plug directly into the spark plug and the engine harness. Replace coils one cylinder at a time or swap all four to maintain uniform performance. Keep connectors clean, torque bolts to factory specs and inspect spark plugs—worn plugs can shorten coil life.

• Disconnect battery before beginning work to avoid shorts.
• Remove coil harness clips, unbolt coil, replace and torque to spec.
• Check and replace spark plugs if worn or out of gap range.
• Re-scan for codes after installation to confirm resolved misfires.

Who is this for: The BDFHYK UF596-compatible four-pack is aimed at DIY mechanics, independent shops and fleet owners who service Toyota-family vehicles listed above and want a cost-effective OE-style replacement. It suits anyone replacing failing coils to restore driveability or performing preventive maintenance on higher-mileage engines. Verify fitment by vehicle year and OEM part number before purchase to ensure direct compatibility.
