BDFHYK Ignition Coil & Spark Plug Kit UF648/97390 for Jeep Wrangler 2012–2017 — Iridium Plug, Plug-and-Play

BDFHYK Ignition Coil UF648 paired with spark plug 97390 is a plug-and-play replacement kit designed to restore ignition performance on compatible Jeep, Dodge, Chrysler, Ram and Volkswagen models.

This kit combines a high-quality coil pack (UF648) and an iridium-tipped spark plug (97390) to address common ignition symptoms such as rough idle, poor throttle response, hard starts, and increased fuel use. Engineered with premium materials — including silicon steel cores, imported rubber seals, varnished windings and an iridium electrode — the components are built for longer life and consistent spark delivery. Compatibility covers many model years and platforms, but always confirm OE numbers and fitment before purchase.

Which vehicles can use this UF648 coil and 97390 spark plug kit?

The set fits a range of Chrysler, Dodge, Jeep, Ram and Volkswagen vehicles across several model years. Fitment includes Jeep Wrangler (2012–2017), Jeep Grand Cherokee (2011–2015), Jeep Cherokee (2014–2022), and multiple Dodge and Chrysler vehicles; verify your vehicle’s engine code and OE part numbers first.

How do these components improve driving when installed?

Replacing aged coils and plugs often restores stable spark timing and combustion, which improves starting reliability, throttle response and overall smoothness. The iridium tip promotes precise ignition and longevity compared with standard plugs, while the coil construction resists heat and electrical stress.

• Smoother idle and fewer misfires after replacement.
• Quicker, more consistent engine starts.
• Better throttle response and transient acceleration feel.
• Durability from premium materials reduces replacement frequency.

What are the build features and quality details of the UF648 coil and 97390 plug?

The ignition coil uses a silicon steel magnetic core, high-grade rubber components from Japan, and varnished copper windings sourced from Germany to resist degradation. The spark plug uses an iridium electrode and a durable ceramic insulator to maintain spark gap and performance under stress.

• Coil: silicon steel core, imported rubber seals, varnished wire windings for heat resistance.
• Spark plug: iridium electrode and advanced ceramic for stable sparks and longevity.
• Manufacturing backed by a supplier with over a decade of automotive parts experience.
• Package intended as direct replacement—confirm plug gap and torque specs during install.

When should I replace ignition coils and spark plugs together?

If your vehicle has high mileage (commonly over ~80,000 km) or shows signs like rough running, slow acceleration, or higher fuel consumption, swapping coils and plugs together can prevent repeat work and restore balanced cylinder operation. Replacing both ensures the new plugs are driven by reliable coil output for optimal combustion.

• Consider replacing as a pair when multiple cylinders misfire or misfire codes appear.
• Plugs often wear before coils fail; replacing together saves diagnostic time.
• Follow manufacturer torque and gap specs during installation for safety.

Who this is for: Mechanics, DIY enthusiasts, and fleet owners who need a cost-effective, higher-grade replacement ignition coil and spark plug that match factory-style fitment for a range of Jeep, Dodge, Chrysler, Ram and Volkswagen vehicles. If you need improved startability, restored throttle response, or are performing routine ignition maintenance, this BDFHYK UF648 + 97390 kit is designed as a durable, drop-in replacement—just confirm OE numbers and vehicle compatibility before ordering.
