Ignition Coil & Iridium Spark Plugs for Honda Pilot (2009-2015) 3.5L V6

High-Energy Ignition Coil & Iridium Spark Plug Kit for 2009-2015 Honda Pilot (J35Z4 / YF3-YF4)

Restores lost power and corrects misfires by providing a consistent, high-voltage spark for optimal combustion efficiency.

The Stock Pilot Weakness

The factory ignition coils on the J35Z4 engine are notorious for thermal degradation over time due to their proximity to exhaust components and frequent heat cycling. Additionally, the Variable Cylinder Management (VCM) system places uneven operational wear on the rear bank spark plugs and coils. This unequal load leads to fouled electrodes, unstable idle, parasitic power loss, and eventual P0300-series misfire codes. As mileage increases, the internal epoxy inside the OEM coils breaks down, causing micro-voltage leaks and weak spark delivery under load.

The Engineering Solution

This comprehensive ignition overhaul kit addresses these inherent design flaws by utilizing advanced materials for superior dielectric strength. The upgraded ignition coils feature high-grade copper windings and premium high-temperature silicone boots to resist extreme heat soak and prevent voltage arcing to the cylinder head. Paired with precision iridium-tipped spark plugs, this system ensures an ultra-fine, highly focused spark. The robust iridium alloy provides exceptional resistance to electrical erosion, significantly lowering the ignition system's voltage requirements while promoting a complete fuel burn. This mechanical synergy results in restored factory horsepower, stabilized torque output, and improved throttle response, and optimized fuel economy, easily enduring the harsh thermal conditions of J-Series VCM operation.

Common Questions

Will this ignition coil and spark plug kit fit my 2009-2015 Honda Pilot?
Yes. This kit is built specifically for the 2009-2015 Honda Pilot equipped with the 3.5L J35Z4 V6 engine (YF3 and YF4 chassis).

Which generation and chassis codes of the Honda Pilot does this kit fit?
This kit is engineered specifically for the 2009-2015 second-generation Honda Pilot (YF3 and YF4 chassis) with the J35Z4 engine and UF624 / 30520RN0A01 specification.

What OEM and aftermarket part numbers does this coil kit replace?
The ignition coils directly replace OEM part number 30520RN0A01 as well as aftermarket reference numbers UF624, EBC1027, and GN10426.

How does this kit hold up against heat soak and VCM wear?
The coils use high-grade copper windings and high-temperature silicone boots to resist heat soak and prevent voltage arcing, while the iridium-tipped spark plugs resist electrical erosion on VCM-Equipped J35Z4 engines.

What symptoms on the 3.5L V6 does this ignition overhaul address?
Replacing worn coils and fouled plugs corrects weak spark delivery, unstable idle, P0300-series misfire codes, and VCM-related hesitation to restore factory 250 hp and 253 lb-ft output.
