ENA Ignition Coil & Spark Plug Wire Kit — Set of 3 Coils, 6 Platinum Plugs for Toyota 3.4L (1995–2004)

ENA’s set combines three replacement ignition coils with six platinum spark plugs and a full wire set designed to restore reliable ignition for Toyota 3.4L engines from 1995–2004. This comprehensive kit replaces factory coils, spark plugs, and high-tension leads in compatible Toyota models such as the 4Runner, T100, Tacoma, and Tundra. Each component is manufactured to meet or exceed original equipment specifications so installation is straightforward and the parts work together to reduce misfires, rough idling, and ignition-related driveability issues. The package is offered as a direct-fit aftermarket replacement for part numbers including UF156, C1041, 90919-02212, 5C1308, and E679.

How will this kit affect engine performance and drivability?

Replacing worn coils, plugs, and wires returns proper spark delivery across all cylinders, which stabilizes combustion and reduces symptoms like stumbling or hesitation. While results depend on the rest of the ignition and fuel systems, fresh components typically improve idle quality and throttle response.

• Restores consistent spark timing and strength across cylinders
• Reduces misfires that can trigger check engine lights
• Improves cold starts and steady idling
• Optimizes fuel burn for smoother acceleration

Are these parts compatible with my Toyota model and engine?

This ENA kit is built specifically for Toyota 3.4L V6 engines produced 1995–2004. Fitment covers popular platforms like the 4Runner, Tacoma, Tundra, and T100 when matched to the listed OE references. Verify compatibility with your VIN or the vehicle’s existing part numbers before purchase.

• Fits Toyota 3.4L V6 engines (1995–2004)
• Replaces OEM references: UF156, C1041, 90919-02212, 5C1308, E679
• Check vehicle fitment guide or VIN to confirm exact match
• Direct-fit design for straightforward replacement

What are the build and quality features of the ENA components?

ENA manufactures these coils, platinum spark plugs, and wires to meet or exceed OE standards and subjects them to quality control testing. Materials and construction are chosen to resist heat and vibration common in engine bays, while the spark plugs use platinum tips for longer service life and stable ignition performance.

• Coils engineered for original equipment fit and function
• Platinum-tipped spark plugs for durability and reliable firing
• High-quality ignition wires designed for low electrical loss
• Quality control checks to ensure consistent performance

How easy is installation and what should I expect during the swap?

The kit’s components are made for direct replacement, allowing most mechanically inclined owners to complete the job with common tools. Expect to follow standard ignition service procedures: safely disconnect the battery, remove old coils and wires, swap in the new plugs and connectors, then reassemble and verify operation.

• Direct-fit parts reduce modification or fabrication needs
• Basic hand tools and torque wrench sufficient for most installs
• Replace plugs first, then wires, then coils to simplify routing
• Clear any stored trouble codes after installation if necessary

Who is this for? This ENA ignition kit is aimed at owners and independent mechanics who need a complete ignition refresh for Toyota 3.4L engines from the late ’90s to early 2000s. It suits drivers experiencing ignition-related symptoms—such as misfires, poor idle, or intermittent stalling—as well as those performing preventive maintenance to maintain drivability and avoid catalytic converter damage from ongoing misfires. Verify vehicle compatibility before ordering to ensure correct application.
