UF660 Ignition Coil & AP5325 Spark Plug Kit for Porsche Cayenne & Panamera

Rough idle, hard starting, hesitation under load, or a cylinder-specific misfire can involve an ignition coil or worn spark plug, but wiring, injectors, fuel delivery, intake leaks, sensors, compression, timing, and other mechanical conditions can create similar symptoms. This BDFHYK ignition service package contains 8 UF660-style ignition coils and 8 AP5325-reference spark plugs for the listed Porsche Cayenne and Panamera applications below.

Porsche Cayenne 4.8L V8 & Panamera 3.6L V6 / 4.8L V8 Fitment for UF660 / AP5325

Confirm the exact model, year, engine displacement, original coil reference, connector shape and keying, coil body, mounting area, boot profile, and AP5325 spark plug reference before ordering. Do not select this kit by Porsche model name alone because other engines and ignition configurations may exist in the same model-year range.

What Is Included in the UF660 & AP5325 Porsche Ignition Set?

• 8 UF660-style ignition coils
• 8 AP5325-reference spark plugs
• Eight-coil and eight-plug package quantity

Quantity note: The 8+8 package matches an eight-cylinder service quantity after exact 4.8L V8 fitment is confirmed. For a listed 3.6L V6 Panamera application, confirm the service quantity required before ordering because this SKU contains eight coils and eight spark plugs, which exceeds the V6 cylinder count.

UF660 / AP5325 Service Scenarios for Porsche Cayenne & Panamera

Rough Idle or Cylinder Misfire

Inspect the affected ignition coil, spark plug, connector, wiring, boot, and plug well first. Fuel-delivery faults, intake leaks, sensor issues, compression, timing, and other mechanical conditions can create similar symptoms.

Hesitation Under Load

A weak ignition component may become more noticeable during acceleration. Confirm the affected cylinder and component condition before replacement rather than treating hesitation alone as proof of a failed ignition coil.

V8 Ignition Maintenance

For a confirmed listed 4.8L V8 application, the 8+8 package provides an eight-cylinder service quantity. For a 3.6L V6 Panamera application, confirm the actual quantity required before ordering.

How to Confirm UF660 and AP5325 Fitment Before Ordering

• Confirm the exact Porsche model, model year, and engine: listed Cayenne 4.8L V8, Panamera 4.8L V8, or Panamera 3.6L V6 application.
• Compare UF660 and the listed 948602104xx references with the original ignition coil.
• Check connector shape and keying, coil body, mounting area, and boot profile.
• Confirm AP5325 against the removed spark plug or exact vehicle service information.
• For a 3.6L V6 Panamera, confirm the required component quantity before ordering this 8+8 package.

Installation Checks for the UF660 & AP5325 Porsche Kit

• Work on a cool engine and keep debris out of the spark plug wells.
• Inspect wiring, connectors, boots, plug wells, oil, and moisture.
• Compare every new ignition coil and spark plug with the removed component before installation.
• Use the exact vehicle service specification for spark plug gap and tightening torque.
• Verify connector seating and recheck stored or returning misfire codes after service.

Important: These are BDFHYK OE-style aftermarket service components, not factory-branded Porsche parts. If a misfire or drivability symptom remains after ignition service, continue diagnosis of the affected cylinder and related systems.
