For ProStreetOnline fitment, I’d require customers to compare the original coil against UF413 / D510C / 12570616 rather than relying solely on displacement.

What Vehicles Fit UF413 Ignition Coils?

The supplied listing provides a broad application list but does not provide trustworthy model-year ranges for every vehicle. I would therefore avoid inventing years for the product catalog.

Advertised applications include compatible versions of:

*Exact engine, year, coil shape and OE number must be verified.

Important: Square Coil vs. Round Coil

This is probably the most important piece of information on the entire product page.

This package uses the UF413 square-style ignition coil.

GM vehicles can use different coil designs even when the engines look extremely similar.

You’ll commonly encounter descriptions such as:

Square coils
Round coils
D510C-style coils
D514A-style coils

They are not automatically interchangeable.

Before ordering, compare:

• Coil housing shape
• Electrical connector
• Mounting points
• OE number
• Engine application

Don’t order simply because the truck has a 5.3L LS-family V8.

“5.3 Chevy” narrows things down about as effectively as “black pickup truck.”

Chevrolet Silverado UF413 Ignition Coils

The Silverado is one of the primary commercial applications for this product.

Compatible engines may include select:

• 4.8L V8
• 5.3L V8
• 6.0L V8
• 6.2L V8

But again, displacement alone does not guarantee UF413 compatibility.

A Silverado product page should prominently display:

VERIFY SQUARE UF413 / D510C COIL BEFORE ORDERING

That’s worth putting near the Add to Cart button.

Chevy Tahoe and Suburban

Compatible Tahoe and Suburban V8 applications are also listed.

These vehicles commonly accumulate substantial mileage, heat cycles and towing duty, making ignition-system condition increasingly important as they age.

Symptoms such as rough idle, hesitation or a cylinder-specific misfire can indicate ignition trouble—but don’t automatically condemn all eight coils.

GMC Sierra and Yukon

Compatible GMC Sierra and Yukon/Yukon XL applications share much of their engine architecture with Chevrolet trucks and SUVs.

Again, verify the physical coil style and OE number before ordering.

Cadillac Escalade

The supplied description also identifies compatible Cadillac Escalade applications.

Because Escalades were offered with several V8 configurations across generations, I would not publish a blanket year range without VIN/engine-level confirmation.

Why GM LS Engines Use Spark-Plug Wires

An LS-family engine doesn’t necessarily place the ignition coil directly over the spark plug.

Instead, many use coil-near-plug ignition.

Each cylinder has its own coil mounted to the valve-cover area, while a short plug wire carries the high-voltage output from the coil to the spark plug.

This gives the system individual coil control while keeping the coils away from the extremely hot exhaust-side spark-plug location.

That’s why this kit includes both:

8 ignition coils + 8 plug wires.

Why Replace the Plug Wires?

A good ignition coil can’t reliably fire the plug if its high-voltage connection is compromised.

Plug wires live close to:

• Exhaust manifolds
• Headers
• Cylinder heads
• Engine vibration
• Extreme heat

Over time, the insulation can deteriorate.

Potential problems include:

• Internal resistance
• Cracked insulation
• Burned boots
• Arcing
• Poor terminal contact
• Heat damage

Replacing deteriorated wires along with aging coils can eliminate another potential source of ignition problems.

Signs of a Bad LS Ignition Coil

Common symptoms include:

• Rough idle
• Engine shaking
• Misfire under load
• Hesitation
• Reduced power
• Poor acceleration
• Hard starting
• Check Engine light
• Flashing Check Engine light
• Poor fuel economy

Pro Street’s 7 Bad Ignition Coil Symptoms You Should Never Ignore explains how coil problems typically develop and what to test before replacement.

P0300 on a Chevy 5.3L

A GM V8 experiencing multiple misfires may store:

P0300 – Random/Multiple Cylinder Misfire

Cylinder-specific codes can range from:

P0301 through P0308

But don’t assume P0300 automatically means “buy eight coils.”

Possible causes include:

• Ignition coils
• Spark plugs
• Plug wires
• Fuel injectors
• Intake leaks
• Fuel-pressure problems
• Wiring faults
• Compression problems
• Valvetrain issues

Pro Street’s P0300 Random/Multiple Cylinder Misfire Causes & Fixes provides a diagnostic path before replacing parts.

Check the Spark Plugs

This package contains coils and wires, but not spark plugs according to the supplied product description.

If the coils and wires are being replaced, inspect all eight plugs.

Look for:

• Excessive electrode wear
• Enlarged gap
• Oil contamination
• Carbon deposits
• Fuel fouling
• Cracked porcelain
• Heat damage

Pro Street’s How to Pick Spark Plugs for Your Build explains plug construction, heat range and proper selection.

LS Engine Coil-Swap Diagnosis

One advantage of individual coils is that a cylinder-specific misfire can often be diagnosed by moving components.

For example, suppose the engine stores:

P0304 – Cylinder 4 Misfire

Move the suspect coil to another cylinder.

If the misfire follows the coil, the coil becomes a strong suspect.

If it remains on cylinder four, investigate the plug, wire, injector, wiring and mechanical condition.

This can prevent replacing eight perfectly functional coils because one spark-plug wire decided retirement sounded nice.

Don’t Ignore Plug-Wire Routing

When installing the supplied 8mm wires:

• Seat both boots completely
• Keep wires away from exhaust components
• Avoid sharp bends
• Prevent wires from rubbing against metal edges
• Verify secure coil-terminal engagement
• Check clearance around headers

Modified vehicles with aftermarket headers deserve particular attention.

A plug wire resting against a hot header tube can quickly transform a new ignition service into another misfire diagnosis.

Can UF413 Performance Coils Add Horsepower?

The manufacturer markets these coils as providing enhanced performance relative to worn OE components.

Treat that claim carefully.

Replacing weak coils and damaged wires can restore lost performance by eliminating misfires and improving ignition consistency.

Replacing perfectly functioning factory coils does not automatically create additional horsepower.

Ignition components provide the spark.

They don’t secretly install a camshaft while you’re sleeping.

Who Should Buy This UF413 Coil & Wire Set?

This package makes the most sense for a compatible GM V8 when:

• Several original coils are aging
• Plug wires show heat damage
• Multiple ignition components require replacement
• The engine is receiving a complete ignition refresh
• The existing coils match UF413/D510C
• All eight cylinders use the square-style coil

It can also make sense for compatible LS-based engine swaps where the engine harness and coil configuration are already designed for UF413-style coils.

Is the UF413 8-Coil and Wire Kit Worth It?

For compatible Chevrolet, GMC and Cadillac V8 applications using UF413 square-style coils, this kit provides a convenient complete eight-cylinder coil and wire package.

The combination of:

8 UF413 coils + 8 8mm plug wires

makes it particularly useful for high-mileage GM trucks, SUVs and LS-powered vehicles receiving a complete ignition refresh.

The critical buying requirement is confirming UF413 / D510C / 12570616 compatibility.

Don’t buy it merely because the engine says 4.8, 5.3 or 6.0 liters.
