ENA Ignition Coil Pack Set for Toyota 3.4L V6 — Set of 3 Black Bolt-On Coils (1995–2004)

ENA Set of 3 ignition coil packs delivers plug-and-play replacement coils engineered to restore consistent spark for Toyota 3.4L V6 engines from 1995–2004.

If your 4Runner, Tacoma, T100 or early Tundra is experiencing rough idle, misfires or reduced throttle response and you’ve traced the issue to worn coils, this ENA three-pack provides direct-fit units matched to original mounting, terminal count and 12V electrical specifications. The kit comes as three black bolt-on coils designed to mount to the valve cover with standard connectors so no aftermarket adapters are required. ENA lists cross-reference numbers (UF156, GN10184, 9091902212 and others) to help confirm fitment with factory part catalogs.

How easy is installation for a DIY mechanic?

Installation is straightforward for anyone familiar with basic engine work: remove the old coil packs, unplug the harnesses, bolt the new ENA units to the valve cover and reconnect. No programming or special tools are typically necessary—just common hand tools and careful connector handling.

• Plug-and-play design with factory-style electrical connectors
• Bolt-on mounting to valve cover; terminal quantity: 3
• 12V-rated coils compatible with original wiring
• Includes set of three coils for sequential replacement

What are the technical features and part references?

ENA designs these coil packs to meet the original electrical and mechanical specifications so they integrate cleanly with factory ignition systems. The listing includes multiple reference numbers to help match the replacement to OEM or aftermarket part catalogs.

Will replacing with this ENA three-pack improve drivability?

Replacing degraded coils can eliminate intermittent misfires, rough idling and hesitation when accelerating if coils are the root cause. While results depend on overall ignition system condition, fresh coils restore reliable spark delivery to the affected cylinders when installed correctly.

• Targets common misfire symptoms caused by failing coils
• Restores uniform spark output across replaced cylinders
• Works best with properly gapped plugs and good wiring
• Recommended to check related ignition components during install
