Ignition Coil + Iridium Spark Plugs for Dodge Viper (2008-2017) 8.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2008-2017 Dodge Viper

What it Does: The ignition coil and iridium spark plug kit restores factory spark energy and cylinder combustion stability on the 2008-2017 Dodge Viper to eliminate misfires under high-load operating conditions.

The Stock Dodge Viper Ignition Breakdown Under Thermal Load

The naturally aspirated 8.4L Viper V10 produces substantial underhood temperatures within the tightly packaged engine bay of the ZB II and VX I chassis. Over extensive heat cycles, factory coil-on-plug internal epoxy breaks down, inducing high-voltage dielectric leakage and secondary winding decay. Combined with thermal spark plug electrode wear, resistance increases across the gap, causing high-RPM spark blowout, irregular idle, and hesitation during open-loop wide-open throttle acceleration.

The Engineering Solution

This ignition assembly package supplies ten heavy-duty coil packs and matching fine-wire iridium core spark plugs calibrated specifically for the odd-fire V10 displacement. The ignition coils feature heat-resistant resin compounds and high-conductivity copper windings designed to suppress thermal resistance fade. Paired with corrosion-resistant iridium ground and center electrodes, this kit reduces firing voltage demands, delivers continuous arc stabilization under high cylinder compression, and directly supersedes factory reference 5037127AB and UF-642.

Frequently Asked Questions

Does this fit the ZB II and VX I Viper?
Yes, this is a direct fit for the 2008-2017 Dodge Viper equipped with the 8.4L Viper V10 engine.

Do these iridium spark plugs require manual gapping prior to installation?
No, the iridium spark plugs are pre-gapped to factory clearance; mechanical gap tools can damage the fine-wire iridium electrode tip.

The Dodge Viper Caliber

Engineered to handle the violent power delivery and sustained high cylinder pressures of pure American displacement, maintaining consistent spark delivery to all ten combustion chambers across aggressive track and street demands.
