A-Premium Ignition Coil and Iridium Spark Plug Kit — Set of 4 for Toyota 2.4L, Bolt‑on Coils, 1‑Year Warranty

A-Premium’s set of four ignition coils and iridium spark plugs is a complete replacement kit designed to restore reliable ignition performance for compatible Toyota, Lexus, Scion and related models.

This all-in-one kit combines four bolt-on ignition coils with four iridium-tipped spark plugs engineered to meet original equipment dimensions and electrical specs. The parts are matched to fit a range of 2.4L and 2.0L inline-four engines across Camry, Corolla, Highlander, RAV4, Matrix, Solara, Lexus HS250h, Pontiac Vibe and Scion models from the early 2000s through 2012, helping simplify maintenance by replacing both coils and plugs at once.

Which vehicles will this ignition coil and spark plug kit fit?

Fitment covers many 2.4L and selected 2.0L Toyota-family engines built in the U.S. or Japan across model years listed by A-Premium. Always verify with your vehicle’s year, engine code and build location before purchase.

• Camry 2002–2011 (specific builds per year and factory)
• Corolla, Highlander, Matrix, RAV4, Solara, Lexus HS250h, Pontiac Vibe, Scion tC and xB where 2.4L or specified 2.0L engines apply
• Check part reference numbers (e.g., 90919-19023, 90919-02243) against OEM records

How do the electrical and mechanical specifications compare to OEM parts?

The coils use blade terminals and mount to the valve cover with bolts, matching common OEM installation points and torque recommendations. Resistance values are close to factory expectations to provide compatible primary and secondary circuit behavior for reliable spark delivery.

• Coil terminal count: 4 with blade-style connectors
• Primary resistance ~0.79 ohms; secondary ~6 kΩ
• Spark plug thread: 14 mm, gap set to 0.077 in (7.7) and install torque 25–30 N·m

What are the materials, durability, and warranty details?

The spark plugs use an iridium center electrode over a nickel body for improved wear resistance and consistent ignitability compared with standard copper plugs. A-Premium backs the kit with a one-year unlimited-mileage guarantee, offering coverage for manufacturing defects during normal use.

• Iridium-tipped spark plug electrodes for long life
• Bolt-on coil mounting and durable blade terminals for secure connections
• One-year unlimited-mileage warranty against manufacturing defects

What should I know about installation and part references?

Installation is typical for coil-on-plug engines: remove the ignition coil bolts, disconnect the harness, and replace coils and spark plugs following torque specs. Cross-reference the supplied reference numbers to ensure compatibility and avoid misfit purchases.

• Installation torque for plugs: 25–30 N·m; coils mount with bolts to valve cover
• Reference numbers include commonly used OEM and aftermarket cross-IDs for verification
• Simple hand tools and standard torque wrench recommended for proper seating

Who is this for: This kit is intended for DIY mechanics and professional technicians working on Toyota-family 2.4L (and select 2.0L) inline-four engines who want a matched set of ignition coils and iridium spark plugs for a full ignition service. It’s suitable for owners replacing aging coils and plugs to restore consistent starting, idle and throttle response, provided the vehicle matches the listed fitments and reference numbers. Always confirm engine build location and part cross-references before installation to guarantee correct fitment.
