What Vehicles Fit This UF596 / UF619 Kit?

According to the supplied manufacturer fitment:

Important: Match the engine and original coil number. Don’t assume every trim within these model years uses UF596/UF619 coils.

Toyota Corolla 1.8L Ignition Coil Kit

The largest conventional application is:

2009–2017 Toyota Corolla 1.8L L4

This gives ProStreetOnline a strong long-tail product target around searches such as:

2009 Toyota Corolla ignition coils
2010 Corolla 1.8 coil pack
2014 Toyota Corolla ignition coil
2017 Corolla 1.8 spark plugs
UF596 Toyota Corolla

When an aging Corolla develops rough idle, hesitation or a cylinder-specific misfire, the ignition system should be tested before replacing parts.

2017 Toyota Corolla iM

Listed fitment includes:

2017 Toyota Corolla iM 1.8L

This is worth keeping separate from the regular Corolla in your vehicle database.

The Corolla iM essentially continued the Scion iM after Toyota killed the Scion brand, because apparently killing a brand is easier than killing a perfectly good hatchback.

Toyota Matrix 1.8L

Listed application:

2009–2014 Toyota Matrix 1.8L

The 1.8L designation matters.

Don’t automatically assign the product to every Matrix configuration solely from the year.

Toyota Prius 1.8L Hybrid

The kit is listed for:

2010–2015 Toyota Prius 1.8L

Yes, hybrids still have spark plugs and ignition coils.

The electric motor doesn’t eliminate the gasoline engine’s ignition system. The Prius’s 1.8L gasoline engine still requires reliable combustion whenever the engine is operating.

This gives the product another valuable SEO angle:

Prius misfire and ignition maintenance.

Toyota Prius v

Listed fitment:

2012–2017 Toyota Prius v 1.8L

Note the lowercase v when referring to the model.

Again, this is a hybrid application but still uses conventional spark ignition in the gasoline engine.

Lexus CT200h

Listed fitment:

2011–2016 Lexus CT200h 1.8L Hybrid

The CT200h shares significant hybrid powertrain architecture with Toyota’s Prius family, making compatible ignition components relevant to both platforms.

For Pro Street, this creates useful Lexus-specific long-tail terms such as:

CT200h ignition coil
Lexus CT200h spark plugs
UF596 CT200h

Scion iM

Listed application:

2016 Scion iM 1.8L

This is effectively the predecessor to the 2017 Corolla iM and should be maintained as a separate make/model entry in the product database.

Scion xD

Listed application:

2008–2014 Scion xD 1.8L

This broad seven-model-year application gives the kit another useful replacement-parts market.

Pontiac Vibe

Listed fitment:

2009–2010 Pontiac Vibe 1.8L

The Vibe shared substantial engineering with Toyota’s Matrix, which explains why Toyota ignition components appear in compatible Pontiac applications.

Again, specify 1.8L because not every Vibe configuration should automatically be assigned this coil.

Why Replace Coils and Spark Plugs Together?

The ignition coil creates the high voltage necessary to produce a spark.

The spark plug uses that voltage to ignite the compressed air/fuel mixture.

As spark plugs wear, their electrodes erode and the gap can change. That can increase the voltage required for reliable ignition.

On a high-mileage vehicle where both components are aging, replacing the plugs while servicing deteriorated coils can make sense.

For additional information, read Pro Street’s How to Pick Spark Plugs for Your Build.

Why Double-Iridium Spark Plugs?

The supplied 4912-style plugs are described as using iridium on both the center and ground electrodes.

Advantages of the correctly specified iridium plug can include:

• Long electrode life
• Reduced electrode erosion
• Consistent spark gap
• Reliable cold starts
• Consistent ignition over extended mileage

However, don’t market the plugs as creating horsepower.

New plugs and coils can restore performance lost to worn ignition components.

They don’t magically improve a healthy engine beyond its normal capability.

Symptoms of a Bad UF596 Ignition Coil

Common symptoms include:

• Rough idle
• Engine shaking
• Hesitation
• Misfire
• Poor acceleration
• Loss of power
• Difficult starting
• Reduced fuel economy
• Check Engine light
• Flashing Check Engine light

Pro Street’s 7 Bad Ignition Coil Symptoms You Should Never Ignore provides a deeper look at ignition-coil diagnosis.

P0300, P0301, P0302, P0303 and P0304

A four-cylinder Toyota experiencing misfires may store:

P0300 — Random/Multiple Cylinder Misfire
P0301 — Cylinder 1 Misfire
P0302 — Cylinder 2 Misfire
P0303 — Cylinder 3 Misfire
P0304 — Cylinder 4 Misfire

A misfire code does not automatically mean the ignition coil failed.

Possible causes include:

• Ignition coil
• Spark plug
• Fuel injector
• Intake leak
• Wiring problem
• Fuel-delivery problem
• Low compression
• Mechanical engine problem

Pro Street’s P0300 Random/Multiple Cylinder Misfire Diagnosis explains how to approach the problem without randomly replacing components.

Use a Coil-Swap Test

Suppose your Corolla stores:

P0302 — Cylinder 2 Misfire

Move the cylinder-two ignition coil to another cylinder and move a known-good coil into cylinder two.

Run the engine and monitor the misfire.

If the fault moves with the coil, you’ve developed strong evidence that the coil is defective.

If P0302 remains, continue diagnosing that cylinder.

Replacing parts isn’t diagnosis.

It’s shopping with extra steps—and yes, even an ecommerce site should admit that.

Prius Misfires Deserve Proper Diagnosis

Misfires in Prius applications should be diagnosed carefully rather than automatically blamed on ignition coils.

A rough-running gasoline engine may involve ignition, fuel, air or mechanical problems.

Record the codes and freeze-frame data before clearing anything.

Check:

• Spark plugs
• Ignition coils
• Coil connectors
• Injectors
• Intake system
• Engine mechanical condition

The goal is to confirm the problem before installing replacement components.

Inspect the Spark-Plug Wells

Whenever the coils are removed, inspect for:

• Engine oil
• Moisture
• Corrosion
• Dirt
• Carbon tracking
• Damaged coil boots
• Damaged electrical connectors

Installing new coils without correcting oil or water contamination can shorten their service life.

Should You Replace All Four Coils?

This Marsram package makes complete replacement convenient, but all four coils don’t automatically require replacement because one failed.

Replacing the complete set can make sense when:

• Several coils have failed
• All four are original and high mileage
• Multiple boots are deteriorated
• You’re performing a comprehensive ignition service
• You’re already replacing all four plugs

For a relatively low-mileage vehicle with one conclusively failed coil, replacing only the defective component may be appropriate.

Is the Marsram UF596 Coil & Plug Kit Worth It?

For compatible Toyota-family 1.8L engines, the Marsram UF596/UF619 Ignition Coil and 4912 Double-Iridium Spark Plug Kit offers a convenient complete ignition service package.

Its primary applications include:

2009–2017 Toyota Corolla
2009–2014 Toyota Matrix
2010–2015 Toyota Prius
2012–2017 Toyota Prius v
2011–2016 Lexus CT200h
2016 Scion iM
2008–2014 Scion xD
2009–2010 Pontiac Vibe

Four coils plus four plugs allow the major ignition service components to be replaced together.

Verify UF596 / UF619 / 90919-02258 / 90919-02252 against the original components before ordering.
