KacuYelin UF502 Ignition Coil & Iridium Spark Plug Kit - Set of 6, Direct-Fit for 3.5L/4.0L V6

KacuYelin UF502 kit combines six high-performance ignition coils and six iridium spark plugs engineered to restore reliable ignition and optimize fuel delivery for compatible Dodge, Chrysler and Volkswagen V6 engines.

This complete ignition kit is built to replace OE part numbers such as 4606869AA and related revisions, delivering a direct fit for many 3.5L and 4.0L V6 models from 2006–2011. The coils use German-imported copper windings, silicon-steel cores and high-temperature epoxy to maintain stable high-voltage output. The iridium plugs feature a 360° laser-welded center electrode and high-density ceramics for long service life and consistent spark performance. Together, the components are intended to reduce misfires, improve throttle response and help maintain fuel efficiency when installed correctly.

Which vehicles will this UF502 ignition kit fit?

The KacuYelin UF502 kit is designed for specific 3.5L and 4.0L V6 models across Dodge, Chrysler and Volkswagen-built Routan. Confirm year, model, engine displacement and submodel before ordering to ensure compatibility. Fitment covers common passenger vehicles and some minivans produced 2006–2011.

• Dodge: Avenger (2008–2010 3.5L), Challenger (2009–2010 3.5L), Charger (2006–2010 3.5L), Journey (2009–2010 3.5L), Magnum (2006–2008 3.5L), Nitro (2007–2011 4.0L)
• Chrysler: 300 (2006–2010 3.5L), Pacifica (2007–2008 4.0L), Sebring (2007–2010 3.5L), Town & Country (2008–2010 4.0L)
• Volkswagen: Routan (2009–2010 4.0L)

How do the ignition coils improve reliability?

The coils incorporate high-purity copper windings and a silicon steel core to maintain efficient power transmission under heat and vibration. A high-temperature epoxy coating protects the internal components from oxidation and corrosion, helping preserve a steady high-voltage output that reduces the risk of ignition failures and misfires.

• German-imported copper for consistent conductivity
• Silicon-steel core for stable magnetic properties
• Heat-resistant epoxy protects against degradation
• Built to match OE electrical and mechanical mounting

What advantages do the iridium spark plugs offer?

These plugs use a laser-welded iridium center electrode and high-alumina ceramic insulation to deliver a focused, durable spark. The manufacturing process and materials aim to extend service life while resisting electrode wear and carbon buildup compared with standard nickel plugs.

• 360° continuous laser welding for a concentrated spark
• High nickel content and iridium for long electrode life
• 95% alumina ceramic for thermal stability and insulation
• Designed to help reduce deposits and optimize combustion

Will this kit affect fuel economy or emissions?

When coils and plugs are worn, combustion efficiency drops, which can increase fuel consumption and emissions. Replacing both parts with matched components can help restore efficient ignition timing and combustion, potentially improving MPG and lowering exhaust pollutants when other engine systems are in good condition.

• Kit intended to help recover lost combustion efficiency
• Manufacturer cites possible fuel efficiency improvements
• Direct plug-and-play replacement to preserve emissions control
• Always verify ECU codes and engine condition for best results

Who this kit is for: The KacuYelin UF502 ignition coil and iridium spark plug set is aimed at owners, mechanics and DIYers who need an OEM-matching replacement for 3.5L and 4.0L V6 Dodge, Chrysler and Routan engines from the 2006–2011 model years. It suits vehicles experiencing misfires, rough idle, reduced power or increased fuel usage where ignition components are suspected. Before purchase, confirm compatibility using your vehicle year, make, model and engine size to ensure a correct fit. For installation support or questions about fitment, contact the seller with your VIN and vehicle details.
