Ignition Coil + Spark Plugs for Toyota Tacoma (1998-1999) 2.4L 2.7L

Direct-Fit Ignition Coil and Denso Spark Plug Kit for 1998-1999 Toyota Tacoma (N140/N150)

What it Does: The direct-fit ignition kit restores combustion efficiency and eliminates cylinder misfires on the 1998-1999 Toyota Tacoma to ensure smooth throttle response and reliable power delivery.

The Stock Toyota Tacoma Ignition Breakdown

The factory distributorless wasted-spark configuration on the 2RZ-FE and 3RZ-FE engines fires two cylinders simultaneously per coil pack. Decades of underhood heat soak degrade the internal primary and secondary copper windings, cracking the factory epoxy potting. Coupled with high-mileage spark plug electrode erosion, widened plug gaps increase secondary resistance and force aged coils past their dielectric threshold. This results in voltage drop-off, hesitation under load, poor fuel economy, rough idling, and persistent P0300–P0304 diagnostic trouble codes.

The Engineering Solution

This replacement ignition package combines two OEM-grade UF180 dual-tower ignition coils with genuine Denso 4503 Platinum spark plugs. Each ignition coil is manufactured with high-temperature epoxy potting and heavy-gauge winding ratios to resist thermal insulation breakdown. The platinum-tipped spark plugs maintain precise gap dimensions under sustained cylinder pressures, lowering the required arc breakdown voltage and ensuring complete burn cycles across all companion cylinders under towing or commercial load.

Frequently Asked Questions & Fitment Warnings

Does this fit the N140/N150 Tacoma?

Yes, this is a direct fit for the 1998-1999 Toyota Tacoma equipped with the 2RZ-FE 2.4L and 3RZ-FE 2.7L 4-cylinder engines. This kit does not fit 3.4L 5VZ-FE V6 models or pre-1998 distributor-type ignition systems.

Are spark plug wires included with this kit?

No, spark plug wires are not included; this set contains the 2 wasted-spark coil packs and 4 platinum spark plugs only.

The Toyota Durability Standard

The first-generation Tacoma earned its legacy through relentless utility and mechanical endurance. Re-establishing peak ignition spark energy ensures dependable cold-start reliability, clean emissions, and sustained torque under full payload conditions.
