Ignition Coil and Iridium Spark Plugs for Nissan GT-R (2009-2021) 3.8L

High-Output Ignition Coil and Iridium Spark Plug Kit for 2009-2021 Nissan GT-R (R35)

What it Does: The ignition coil and iridium spark plug kit replaces aged factory ignition components on the 2009-2021 Nissan GT-R to eliminate high-boost misfires, stabilize idle quality, and restore peak combustion efficiency.

The Stock Nissan GT-R Ignition Breakdown Under Boost

The twin-turbocharged VR38DETT generates extreme cylinder pressures that place massive dielectric stress on the ignition system. Over time, engine bay thermal soak degrades the factory coil packs' internal epoxy insulation, leading to micro-arcing, secondary winding resistance breakdown, and spark blowout under load. Concurrently, factory plug gaps widen from electrode erosion, requiring higher secondary voltage that degraded 22448-JF00B coils cannot provide. This results in hesitation, stumbling under boost, P0300 multi-cylinder misfire trouble codes, and unburned fuel washing down cylinder walls.

The Engineering Solution

This refresh kit provides six direct coil-on-plug units engineered with high-dielectric epoxy-filled windings and vulcanized heat-resistant boots to prevent voltage leakage and thermal breakdown. Paired with fine-wire iridium spark plugs featuring a 12mm thread, 14mm hex, and 26.5mm reach, the system substantially lowers required ignition voltage. The dense iridium center electrode maintains a tight 0.031-0.035 inch pre-set gap under relentless boost levels, delivering a potent, focused spark kernel that maximizes flame propagation across all combustion chambers of your R35.

What's Included

• 6 Ignition Coils (Black, 3-pin blade connector, COP layout)
• 6 Pre-Gapped Iridium Spark Plugs (12mm thread, 14mm hex, 26.5mm reach)

Frequently Asked Questions & Fitment Warnings

Does this fit the R35 GT-R?

Yes, this is a direct fit for the 2009-2021 Nissan GT-R equipped with the VR38DETT twin-turbo engine across all trims and transmission types.

Do I need to gap the spark plugs or apply dielectric grease prior to installation?

The plugs come pre-gapped to 0.031-0.035 inches, but verifying clearance before installation is advised; a light film of dielectric grease on the coil boot interior is recommended to ensure thermal isolation and simplify future servicing.

The Nissan High-Performance Standard
