What Vehicles Fit UF648 Ignition Coils?

The supplied manufacturer data gives unusually useful year/model information:

Fitment requirement: Vehicle must use the compatible 3.6L or 3.2L Pentastar V6 and UF648-style ignition coil.

Jeep Wrangler 3.6L

The supplied fitment covers:

2012–2017 Jeep Wrangler 3.6L V6

These JK-generation Wrangler applications are an excellent target for the product because the 3.6L Pentastar became the Wrangler’s standard gasoline V6 beginning in this period.

For ecommerce, target phrases such as:

Jeep Wrangler 3.6 ignition coil
JK Wrangler coil pack
UF648 Wrangler ignition coil

These are much stronger purchase-intent keywords than simply “Jeep coil.”

Jeep Grand Cherokee 3.6L

Listed fitment:

2011–2015 Jeep Grand Cherokee 3.6L V6

Do not assign this product to every Grand Cherokee from these years. V8 and diesel configurations require different ignition/service components.

Jeep Cherokee 3.2L

One important application is:

2014–2020 Jeep Cherokee 3.2L V6

The 3.2L Pentastar is related to the 3.6L engine family and uses compatible UF648 coils in the applications specified by the manufacturer.

Make sure the store distinguishes:

Cherokee 3.2L from Grand Cherokee 3.6L.

They’re different vehicles despite Jeep apparently deciding customers didn’t need additional nouns.

Dodge Challenger 3.6L

Listed fitment:

2011–2020 Dodge Challenger 3.6L V6

This is one of the strongest enthusiast applications for Pro Street.

The UF648 is intended for the 3.6L Pentastar V6 Challenger, not the 5.7L Hemi, 6.4L Hemi or supercharged V8 applications.

That distinction should appear prominently on the product page.

Dodge Charger 3.6L

Listed fitment:

2011–2020 Dodge Charger 3.6L V6

Again:

3.6L Pentastar only.

Do not assign UF648 to Hemi-powered Chargers.

Dodge Durango

Listed application:

2011–2015 Dodge Durango 3.6L V6

The Durango was also available with V8 power, making the engine selector essential.

Dodge Grand Caravan

Listed application:

2011–2020 Dodge Grand Caravan 3.6L V6

The long-running Pentastar Grand Caravan application gives this coil significant replacement-market potential.

Dodge Journey

Listed application:

2011–2019 Dodge Journey 3.6L V6

Again, verify engine because not every Journey used the Pentastar V6.

Chrysler 300 3.6L

Listed fitment:

2011–2020 Chrysler 300 3.6L V6

The product should not be assigned to 5.7L or other V8-powered Chrysler 300 applications.

Chrysler 200

Listed fitment:

2011–2017 Chrysler 200 3.6L V6

Chrysler Town & Country

Listed fitment:

2011–2016 Chrysler Town & Country 3.6L V6

This shares much of its drivetrain architecture with the Pentastar-powered Grand Caravan.

Ram 1500 3.6L

Listed applications include:

2013–2018 Ram 1500 3.6L V6
2019–2020 Ram 1500 Classic 3.6L V6

Note the Classic designation for 2019–2020.

Do not automatically extend this product to the newer-generation 2019–2020 Ram 1500 without separate fitment confirmation.

Ram ProMaster

Listed applications include:

2014–2020 Ram ProMaster 1500 3.6L
2014–2020 Ram ProMaster 2500 3.6L
2014–2020 Ram ProMaster 3500 3.6L

These commercial-van applications give the UF648 substantial fleet and work-vehicle relevance.

Symptoms of a Bad Pentastar Ignition Coil

A failing ignition coil may produce:

• Rough idle
• Engine shaking
• Hesitation
• Misfire under load
• Poor acceleration
• Loss of power
• Increased fuel consumption
• Hard starting
• Check Engine light
• Flashing Check Engine light

Pro Street’s 7 Bad Ignition Coil Symptoms You Should Never Ignore explains these symptoms and how to diagnose a suspect coil.

P0300 on a 3.6L Pentastar

A Pentastar experiencing multiple misfires may store:

P0300 – Random/Multiple Cylinder Misfire

Cylinder-specific codes can include:

P0301 through P0306

But don’t assume the ignition coil is automatically responsible.

Other potential causes include:

• Spark plugs
• Fuel injectors
• Intake leaks
• Wiring problems
• Fuel-delivery faults
• Compression problems
• Valvetrain issues

Use Pro Street’s P0300 Random/Multiple Cylinder Misfire Guide before replacing parts.

Don’t Confuse a Pentastar Misfire With a Coil Failure

This is particularly important on Pentastar engines.

A cylinder-specific misfire can originate from the ignition system, but mechanical and valvetrain problems can produce similar symptoms.

If a misfire remains on the same cylinder after swapping the ignition coil and verifying the spark plug, continue diagnosing rather than repeatedly replacing ignition components.

Parts cannon ammunition is expensive.

Check the Spark Plugs

When replacing ignition coils, inspect the spark plugs for:

• Electrode wear
• Excessive gap
• Oil contamination
• Fuel fouling
• Carbon deposits
• Cracked porcelain
• Carbon tracking
• Evidence of overheating

Pro Street’s How to Pick Spark Plugs for Your Build provides additional information on plug selection, materials and heat range.

Should You Replace All Six UF648 Coils?

If you’re selling these as a complete six-coil package, replacing the full set can make sense when:

• Several coils have failed
• All six are original and high mileage
• Multiple coil boots are deteriorating
• The engine is undergoing a complete ignition service
• Several cylinders show ignition-related problems

If one newer coil has conclusively failed and the remaining five are healthy, replacing every coil isn’t automatically required.

Can UF648 Coils Improve Performance?

New coils can restore normal engine operation when deteriorated coils are producing weak or inconsistent spark.

That can restore:

• Smooth idle
• Acceleration
• Throttle response
• Starting reliability
• Normal fuel economy

But replacing six healthy OE coils isn’t going to transform a V6 Challenger into a Hellcat.

If only ignition coils were that ambitious.

Is the UF648 Ignition Coil Set Worth It?

The UF648 ignition coil covers an unusually large range of Pentastar-powered vehicles.

Its strongest applications include:

• Jeep Wrangler
• Jeep Grand Cherokee
• Jeep Cherokee
• Dodge Charger
• Dodge Challenger
• Dodge Durango
• Dodge Grand Caravan
• Dodge Journey
• Chrysler 200
• Chrysler 300
• Chrysler Town & Country
• Ram 1500
• Ram ProMaster

Verify UF648 / C1791 / GN10616 / 5149168AI and the correct 3.6L or 3.2L Pentastar V6 before ordering.
