Denso Direct Ignition Coil for Toyota/Scion/Lexus/Pontiac - 673-1310 Stick Coil, Micro-Driver Durability

This replacement coil fits a range of vehicles—including Toyota C-HR, Corolla, Matrix, Prius (regular, Plug-In and V), Scion iM and xD, Lexus CT200h, and Pontiac Vibe—covering many model years. Engineered by Denso, the part continues the brand’s long history of compact stick-type coil design and micro-driver electronics to provide consistent ignition output without the need for a high-tension cable. It is produced and inspected to meet factory-level expectations for fit and function.

How does this coil differ from older ignition systems?

The Denso 673-1310 is a stick-style direct ignition coil that installs directly over the spark plug, eliminating separate high-voltage spark plug wires. Its compact design reduces electrical losses and shortens the ignition path, helping deliver a focused spark to the combustion chamber. Built-in driver circuitry and optimized windings improve reliability compared with oversized or generic coils.

• Direct-to-spark-plug stick coil eliminates spark plug cables
• Micro driver circuitry for accurate firing control
• Diagonal inductive windings for consistent energy delivery
• Form-fit design engineered for specific vehicle applications

Will this coil fit my vehicle?

Denso 673-1310 is specified to replace OEM coils on a number of model years and trims—check years and models carefully before ordering. It fits many Toyota, Scion, Lexus, and Pontiac vehicles listed in the product compatibility information, and it’s built to the same physical dimensions required by those engines. Always verify part numbers against your vehicle VIN or existing coil stamping to ensure proper match.

• Fits Toyota: C-HR, Corolla, Matrix, Prius, Prius Plug-In, Prius V, Corolla iM (select years)
• Fits Scion: iM and xD (select years)
• Fits Lexus CT200h and Pontiac Vibe (select years)
• Confirm compatibility with VIN or OEM part number before purchase

What performance and durability benefits can I expect?

This coil is designed for stable, high-energy ignition pulses that support smooth combustion under typical driving conditions. While individual results depend on engine condition and maintenance, Denso coils are manufactured and tested to reduce failures caused by heat, moisture, and vibration. Replacing a failing coil with a direct-fit Denso unit restores consistent spark timing and energy output.

• Engineered for consistent high-voltage output across operating range
• Manufacturing and inspection protocols help minimize early failures
• Compact, heat-resistant materials suited for engine bay environments
• May improve driveability if previous coil was degraded

How difficult is installation for a DIYer?

Installation is straightforward for most mechanically inclined owners: the coil plugs directly onto the spark plug and connects to the engine wiring harness. Basic hand tools and a modest amount of space around the ignition coil bore are usually all that’s needed. If you’re unsure, consult a repair manual or a professional technician to avoid damage to the new coil or surrounding components.

• Direct-fit replacement—no special adapters required
• Basic tools typically required: ratchet, spark plug socket, torque wrench
• Follow vehicle-specific torque specs and electrical connector care
• Professional installation recommended if access or experience is limited

Who is this for: Denso 673-1310 is aimed at owners and technicians needing a direct-fit replacement coil for the listed Toyota, Lexus, Scion, and Pontiac vehicles. It’s suitable for routine maintenance, replacing a failed coil, or restoring proper ignition performance after misfire or rough-idle diagnostics. Choose this part when you want an OEM-quality stick-type coil designed by a long-standing ignition-system supplier.
