What Vehicles Fit the ENA UF549 Ignition Coil?

According to the supplied application data, UF549-compatible coils are listed for the following vehicles.

Nissan Altima

2007–2018 Nissan Altima 2.5L

The Altima is one of the strongest applications for this product because many four-cylinder Altimas use four individual coil-on-plug ignition coils.

If your Altima is experiencing a misfire, don’t automatically replace all four coils. Pro Street has a live How to Test a Nissan Altima Ignition Coil diagnostic guide that explains how ignition problems can create starting, spark and misfire issues.

Nissan Sentra

Listed applications include:

• 2009–2012 Nissan Sentra 2.0L
• 2007–2012 Nissan Sentra 2.5L
• 2013–2019 Nissan Sentra 1.8L
• 2018 Nissan Sentra 1.6L

Different Sentra generations used different engines, which makes verifying the exact engine particularly important.

Nissan Versa

Listed applications include:

• 2007–2012 Nissan Versa 1.8L
• 2014–2019 Nissan Versa Note 1.6L

The four-coil package makes sense for compatible four-cylinder Versa applications when performing a complete ignition-system refresh.

Nissan Cube

2009–2014 Nissan Cube 1.8L

The Cube’s four-cylinder engine makes this another logical application for a complete four-piece coil set.

Nissan Rogue

2008–2013 Nissan Rogue 2.5L

A weak ignition coil can produce rough idle, hesitation and misfires that become particularly noticeable during acceleration.

Nissan Frontier

The supplied fitment data lists selected:

• 2007–2008 Nissan Frontier 2.4L
• 2011–2012 Nissan Frontier 2.4L
• 2015 Nissan Frontier 2.4L
• 2016–2019 NP300 Frontier 2.5L

Be especially careful with Frontier fitment because North American Frontier engine offerings differ from international NP300/Frontier applications.

Nissan Pathfinder

2014 Nissan Pathfinder 2.5L is included in the supplied application data.

Again, verify engine and coil number before purchase because Pathfinder engine configurations vary substantially.

Other Listed Nissan Applications

The supplied manufacturer fitment also identifies:

• 2012–2018 Nissan March 1.6L
• 2013–2018 Nissan Tiida 1.6L
• 2016–2019 Nissan NP300 2.5L
• 2008–2017 Nissan X-Trail 2.5L
• 2009–2013 Nissan Urvan 2.5L

Some of these are international-market vehicles rather than common U.S.-market applications.

Infiniti Applications Require Special Attention

The supplied compatibility data also lists several Infiniti models:

• 2014–2017 Infiniti QX60 2.5L
• 2009–2013 Infiniti FX50 5.0L V8
• 2014–2017 Infiniti QX70 5.0L V8
• 2011–2013 Infiniti M56 5.6L V8
• 2014–2019 Infiniti Q70 5.6L V8
• 2015–2019 Infiniti Q70L 5.6L V8

Here’s the important part:

This package contains four ignition coils.

A V8 requires eight coils when replacing the complete set.

Therefore, even if the individual UF549-style coil is compatible with a listed V8 application, one four-piece package is not a complete V8 ignition-coil replacement set.

Customers replacing all eight coils would need the appropriate quantity after confirming exact fitment.

That distinction belongs prominently on the Pro Street product page.

Suzuki Equator

The supplied application data also lists:

2009–2012 Suzuki Equator 2.5L

Since the Equator shared substantial architecture with the Nissan Frontier, Nissan-derived components appear throughout the platform.

Still, verify the exact OE/interchange number before ordering.

Why Replace Nissan Ignition Coils?

Modern coil-on-plug ignition systems place an individual ignition coil directly over each spark plug.

Each coil converts low-voltage electrical power into the high voltage necessary to fire its spark plug.

When a coil begins deteriorating, you may experience:

• Engine misfire
• Rough idle
• Hesitation
• Loss of power
• Poor acceleration
• Check Engine light
• Flashing Check Engine light
• Reduced fuel economy
• Hard starting
• Shaking during acceleration

These symptoms can become progressively worse as the coil deteriorates.

For a deeper explanation, read Pro Street’s live 7 Bad Ignition Coil Symptoms You Should Never Ignore guide.

Bad Ignition Coil Symptoms Aren’t Proof the Coil Is Bad

This is where diagnosis becomes important.

A rough idle and P0302 code don’t automatically mean cylinder two needs an ignition coil.

Similar symptoms can be caused by:

• Worn spark plug
• Excessive spark-plug gap
• Fuel injector failure
• Vacuum leak
• Wiring problem
• Poor electrical connection
• Low compression
• Fuel-delivery problem
• Engine mechanical failure

The trouble code tells you where the computer detected a problem.

It doesn’t necessarily tell you which part to buy.

Otherwise mechanics would just be highly trained barcode scanners.

Nissan Misfire Diagnosis

Pro Street has been covering Nissan ignition diagnosis for years, including dedicated Nissan misfire testing.

For Nissan owners, our live P0303 Nissan 3.5L – How to Test VQ35 Ignition Coil article demonstrates how Nissan misfire diagnosis involves more than simply replacing whichever coil sits above the cylinder identified by the trouble code.

Although that VQ35 application uses different coils from the four-cylinder engines covered by this kit, the diagnostic principle remains useful:

Confirm the fault before replacing the part. Don’t automatically assume it’s your coil, faulty Altima fuel injectors can cause problems as well. 

Test the Coil by Moving It

One of the simplest diagnostic techniques on many coil-on-plug engines is a coil swap.

Suppose your Nissan stores:

P0302 – Cylinder 2 Misfire Detected

You can:

1. Record all trouble codes and freeze-frame data.
2. Remove the cylinder-two ignition coil.
3. Move it to another cylinder.
4. Install the known-good coil in cylinder two.
5. Reassemble everything correctly.
6. Run the engine.
7. Rescan the ECU.

If the misfire moves to the cylinder receiving the suspect coil, you’ve developed strong evidence that the coil is faulty.

If P0302 remains, keep diagnosing cylinder two.

Don’t punish an innocent ignition coil for somebody else’s crime.

Should You Replace One Coil or All Four?

This ENA package contains four coils, making it particularly useful for a four-cylinder Nissan undergoing a complete ignition refresh.

Replacing all four may make sense when:

• Mileage is high
• All four coils are original
• Multiple coils have already failed
• Several coils show cracking or deterioration
• You’re replacing the spark plugs simultaneously
• You want a matched replacement set

Replacing only one may make sense when:

• One coil has conclusively failed
• The other coils were recently replaced
• Mileage is relatively low
• The remaining coils test correctly

There isn’t a universal rule that every functioning coil must be thrown away because one failed.

Inspect the Spark Plugs

If you’re replacing coils, inspect the spark plugs.

A worn spark plug can increase the voltage required to create a spark.

That places additional demand on the ignition coil.

Look for:

• Worn electrodes
• Excessive plug gap
• Carbon deposits
• Oil fouling
• Fuel fouling
• Cracked porcelain
• Evidence of overheating

Pro Street’s live How to Pick Spark Plugs for Your Build guide explains why plug type, heat range and application matter.

For a stock Nissan, always begin with the factory-recommended plug specification for the exact engine.

Nissan Altima Ignition Problems

The Altima deserves particular attention because 2007–2018 2.5L Altima applications make up a major portion of the advertised fitment.

If your Altima has:

• Rough idle
• P0300
• P0301–P0304
• Hesitation
• Hard starting
• Loss of power

start by retrieving the trouble codes.

Then inspect the plug and coil on the affected cylinder.

Pro Street’s live How to Test a Nissan Altima Ignition Coil guide provides additional Nissan-specific diagnostic information.

Can a Bad Coil Cause Poor Fuel Economy?

Yes.

When a coil doesn’t provide reliable spark, combustion can become incomplete.

The engine may:

• Waste fuel
• Lose power
• Develop rough running
• Increase emissions
• Send unburned fuel into the exhaust

Replacing a genuinely faulty coil can therefore restore lost fuel economy.

The important word is restore.

Installing four new ignition coils on an engine whose original coils work perfectly isn’t a secret fuel-economy modification.

If it were, gas stations would presumably be lobbying against ignition coils.

Don’t Drive With a Severe Misfire

An active misfire can send unburned fuel into the catalytic converter.

That fuel can burn inside the converter and generate extreme temperatures, potentially damaging the catalyst.

A flashing Check Engine light associated with severe shaking or power loss should therefore be treated seriously.

Ignoring a $40 ignition problem until it becomes a four-figure catalytic-converter problem is not the kind of upgrade we’re looking for.

ENA UF549 vs. UF509

The supplied interchange data includes both UF549 and UF509.

Because aftermarket interchange catalogs sometimes group coils across related applications, don’t rely on the UF number alone if there is uncertainty.

Compare:

• Year
• Make
• Model
• Engine
• Electrical connector
• Coil dimensions
• Mounting design
• OE Nissan number

The strongest Nissan references supplied include:

22448-ED000
22448-JA00A
22448-JA00C
22448-1KT1A

Matching the original component is far safer than ordering based solely on “Nissan 2.5.”

Who Should Buy the ENA 4-Piece Ignition Coil Set?

This set makes the most sense for owners of compatible four-cylinder Nissan vehicles such as selected:

Altima, Sentra, Versa, Versa Note, Cube and Rogue models

where all four ignition coils are being replaced together.

It can also provide four replacement coils for other compatible applications where fewer or more than four total coils are required.

The critical step is verifying fitment first.

Is the ENA UF549 Ignition Coil Set Worth It?

For a compatible Nissan four-cylinder engine, the ENA UF549 4-Piece Ignition Coil Pack provides a convenient way to refresh the complete coil-on-plug ignition system at once.

Its broad advertised compatibility includes some of Nissan’s most common vehicles, particularly the Altima, Sentra, Versa, Cube and Rogue.

Combine new coils with properly selected spark plugs and a correctly diagnosed ignition problem, and you can restore smooth idle, acceleration and reliable combustion.

But remember:

Four coils fix four bad coils.

They do not fix a vacuum leak, dead injector or cylinder with no compression.

The parts cannon remains undefeated at emptying wallets.
