BELKEBIR Ignition Coil Pack & Iridium Spark Plug Kit for 1.5L Toyota/Scion — Set of 4, OEM Fit, Direct Replacement

BELKEBIR’s 4-piece ignition coil pack and iridium spark plug set replaces UF316/C1304/90080-19021 and restores reliable spark for 1.5L Toyota and Scion engines.

Designed as a direct, plug-and-play replacement for many 1.5L L4 Toyota and Scion models, this kit includes four ignition coils paired with iridium spark plugs engineered to match OEM fit and function. Each component is manufactured to deliver consistent spark, strong electrode life and straightforward installation so you can correct misfires, improve throttle response and maintain fuel efficiency without modifying your engine.

Will these parts fit my Toyota or Scion with a 1.5L engine?

Yes — this BELKEBIR kit targets vehicles with the 1.5L inline-4 engines that use UF316/C1304-style coils and 90080-19021 spark plug assemblies. Confirm compatibility by checking your current part numbers against the replacements listed.

• Compatible models: 2001–2009 Prius, 2007–2018 Yaris, 2012–2019 Prius C, 2000–2005 Echo, 2004–2006 Scion XA/XB.
• Replaces common OEM numbers: UF316, C1304, 90080-19021, 9091902237 and others.
• Designed to match OEM mounting points, electrical connectors and reach.

How will these coils and plugs affect engine performance?

The kit provides stable, higher-energy ignition and durable iridium electrodes for consistent combustion. That stability reduces the chance of misfires, smooths idle and can help restore original acceleration and responsiveness that may have degraded with worn parts.

• Iridium plugs offer long life and consistent spark quality.
• Coil packs deliver strong, even voltage to each cylinder.
• Better ignition timing stability for more reliable starts and smoother cruising.

Is installation difficult and do I need special tools?

Installation is straightforward for anyone comfortable with basic engine maintenance; the coils and plugs are direct OEM-style replacements. Most jobs require only common hand tools and a torque wrench for correct spark plug seating, making it an achievable DIY task or a quick shop replacement.

• Plug-and-play coil connectors — no cutting or splicing required.
• Use a spark plug socket, ratchet and torque wrench for best results.
• Expect roughly 30–60 minutes for a four-cylinder swap for a DIYer.

What are the materials and quality features of the spark plugs and coils?

The spark plugs use high-grade iridium for the center electrode to increase wear resistance and maintain gap stability over time. Coils are built to meet or exceed OEM electrical and thermal performance, ensuring consistent energy delivery under normal driving conditions.

• High-quality iridium electrodes for longevity and stable gaps.
• Coil packs manufactured to OEM specs for fit and electrical output.
• Tested for reliable cold starts and continuous operation.

Who this is for: This BELKEBIR kit is aimed at owners and mechanics of Toyota and Scion vehicles with 1.5L L4 engines who need a direct replacement for worn ignition coils and spark plugs. It’s a good choice for drivers noticing misfires, rough idle, decreased throttle response or those performing scheduled maintenance and seeking OEM-style reliability with iridium longevity.
