Bosch ignition coil 0221504048 for Chrysler Dodge Jeep Ram — OE-fit, corrosion-resistant high-temp design

BOSCH 0221504048 is a direct-fit OE-quality ignition coil designed to restore strong, consistent spark for compatible Chrysler, Dodge, Jeep, Ram and select Volkswagen engines.

This Bosch ignition coil replaces worn or failing coils to help your engine start reliably and run smoothly. Engine management components like coils influence ignition energy and electrical delivery to spark plugs; Bosch engineers these coils to meet or exceed original equipment standards, with corrosion-resistant connections and materials chosen for high temperature and vibration environments. Use the vehicle fitment checker to confirm compatibility with your model and engine before purchase.

How will this coil affect starting and engine smoothness?

Installing a healthy ignition coil improves voltage delivery to the spark plug electrodes, which helps ensure consistent combustion across cylinders. That leads to more dependable cold starts, fewer misfires, and steadier idle and acceleration when the rest of the ignition and fuel systems are in good condition.

• Restores proper spark timing and strength for consistent ignition
• Reduces cylinder misfires that cause rough idle or hesitation
• Improves cold-start performance through reliable voltage output
• Fits directly in place of the factory coil for quick replacement

What makes Bosch's 0221504048 different from cheaper aftermarket coils?

Bosch emphasizes OE-level design, quality materials, and manufacturing controls that support long-term reliability under heat and vibration. While budget coils may function short-term, Bosch components are engineered for precise electrical connections and corrosion resistance that maintain performance over many miles.

• Engineered to meet or surpass original equipment specifications
• Corrosion-resistant terminals and robust insulation materials
• Designed to handle high temperatures and mechanical vibration
• Tested for consistent voltage output and service life

Which vehicles and engines is this coil compatible with?

This part is a common replacement across many Chrysler, Dodge, Jeep and Ram models produced in the 2010s and early 2020s, plus some Volkswagen Routan models. Exact fit depends on model year, trim and engine; verify fitment with the vehicle-specific selector or VIN to ensure correct application.

• Chrysler: select 200, 300, Town & Country model years listed by Bosch

How simple is the swap, and what should I check during installation?

For most of the compatible models, the coil is a direct-fit electrical and mechanical replacement that requires basic hand tools. Inspect spark plugs, wiring harness connectors, and the coil mounting area; replacing faulty spark plugs simultaneously often delivers the best results.

• Direct-fit design makes replacement straightforward for DIYers or technicians
• Check plug gaps and replace spark plugs if worn or fouled
• Ensure harness connectors seat cleanly and terminals are corrosion-free
• Tighten mounting bolts to factory torque and recheck after initial drive
