A-Premium Ignition Coil Pack & Iridium Spark Plugs Kit, Set of 4 — Toyota Camry/RAV4/Sienna 2.5L–2.7L Direct-Fit

A-Premium's 4-pack ignition coil pack with iridium spark plugs is a direct-fit replacement kit engineered to restore consistent spark delivery and long-lasting ignition performance for compatible Toyota 4-cylinder engines.

If your Camry, RAV4, Sienna, Highlander or Venza with a 2.5L or 2.7L L4 engine is showing rough idle, misfires, or sluggish starts, worn coils and spark plugs are common suspects. This kit bundles four bolt-on ignition coils and four iridium-tipped spark plugs matched to factory mounting points and electrical connections, designed to fit models from about 2009 through 2018. Materials and specifications focus on durability and reliable combustion while simplifying replacement with plug-and-play fitment and a one-year unlimited-mileage warranty.

How does this kit improve engine starting and idle stability?

Upgrading both coils and spark plugs at the same time reduces variability in spark energy across cylinders, which leads to smoother starts and steadier idling. The iridium center electrodes provide a small, hard-wearing contact point that sustains spark consistency longer than standard alloys.

• Iridium central electrode for extended life and steady ignition
• Blade terminal coils that match original connector style
• Reduced misfires and improved throttle response when installed

Will these parts fit my Toyota, and what reference numbers do they replace?

The kit is engineered for multiple Toyota L4 petrol engines: Camry (2010–2017, 2.5L), RAV4 (2009–2018, 2.5L), Sienna (2011–2013, 2.7L), Highlander and Venza years noted in the product fitment. It replaces numerous OEM and aftermarket reference numbers, making it a versatile direct-replacement option.

• Compatible vehicle list includes Camry, RAV4, Sienna, Highlander, Venza as specified
• Replaces factory codes such as 90919-A2002 and related part numbers
• Designed to match factory mounting and electrical interfaces for easy swap

What are the technical specs and installation details I should know?

Each coil pack in the kit has four terminals and a blade-style electrical end, mounting to the valve cover with a bolt-on design. Spark plugs are nickel body with iridium central electrodes, pre-gapped to about 1.0–1.1 inches and specified thread diameter for direct-fit installation.

• Coil resistance range: approximately 3–12 kΩ for consistent output
• Spark plug thread diameter 14 mm; recommended installation torque 25–30 N·m
• Black finish on coils and factory-style mounting for straightforward replacement

What kind of durability and warranty does A-Premium provide?

A-Premium pairs robust materials with an owner-friendly guarantee: a one-year unlimited-mileage warranty on the ignition coil and spark plug kit. This gives reassurance against early failures while you monitor performance gains after installation.

• Iridium electrodes extend spark plug life roughly three times versus standard plugs
• One-year unlimited-mileage coverage from A-Premium
• Quality control targeted at consistent fit and reliable operation

Who is this for: This kit is intended for owners and technicians working on Toyota 4-cylinder vehicles listed in the fitment, who want a complete ignition refresh—especially when replacing old coils and plugs together makes diagnostic sense. It’s suitable for DIYers with basic mechanical skills and for professional shops seeking a cost-effective direct-replacement solution that aligns with OEM mounting and electrical interfaces.
