Ignition Coil & Iridium Spark Plugs for Infiniti G35 (2007-2008) 3.5L

High-Output Ignition Coil & Iridium Spark Plugs for 2007-2008 Infiniti G35 (VQ35HR / V36)

Restores lost ignition efficiency and eliminates misfires under high load: This comprehensive ignition service kit replaces degraded factory coils and fouled plugs to deliver a consistent, high-energy spark across the entire RPM range.

The Stock VQ35HR Ignition Degradation

As the VQ35HR engine ages, the factory ignition system is highly susceptible to heat cycling and dielectric breakdown. Located deep within the valve covers, the OEM coil packs endure extreme thermal stress, leading to microscopic cracks in the epoxy housing and degraded internal windings. Over time, this increased electrical resistance causes weak spark energy, premature spark plug fouling, and high-RPM misfires. When paired with standard worn spark plugs, the compromised spark front results in incomplete combustion, sluggish throttle response, reduced fuel economy, and potential unburnt fuel passing through the exhaust system, which can ultimately damage the catalytic converters.

The Engineering Solution

This replacement ignition coil and iridium spark plug package is engineered to exceed factory operational parameters. The coils feature upgraded primary and secondary copper windings wrapped in a high-temperature epoxy module, providing superior resistance to thermal breakdown and voltage leakage. The included iridium spark plugs utilize an ultra-fine wire center electrode and a laser-welded ground electrode, requiring less voltage to jump the gap while generating a highly concentrated spark front. This combination ensures complete air-fuel mixture ignition, even under heavy acceleration or high-load conditions. The exact-fit silicone boots and internal suppression resistors prevent radio frequency interference (RFI) while maintaining maximum energy transfer directly to the combustion chamber.

Common Questions

Will this ignition coil and spark plug kit fit my 2007-2008 Infiniti G35?
Yes, this kit is engineered for the 2007-2008 Infiniti G35 V36 Sedan equipped with the 3.5L VQ35HR V6 engine, including Base, Journey, Sport, and X trims.

Does this fit a 2007 Infiniti G35 Coupe with the VQ35DE engine?
This kit is built specifically for the VQ35HR engine found in the V36 chassis (2007-2008 G35 Sedan).

What is included in this tune-up package?
The package includes replacement high-output ignition coils with exact-fit silicone boots and matching laser-welded fine-wire iridium spark plugs.

How are these coils constructed to handle engine heat?
Each coil uses upgraded primary and secondary copper windings encased in a high-temperature epoxy module to resist thermal breakdown and voltage leakage inside the valve covers.

Are these coils and plugs a direct replacement for the factory parts?
Yes, they feature exact-fit silicone boots and internal RFI suppression resistors to install directly in place of the factory VQ35HR ignition components.
