7 Best Spark Plugs for Chevy Equinox in 2026: Find the Right Fit for Your Engine

Chevy Equinox spark plugs are not one-size-fits-all. The right replacement depends on your model year, engine, and the plug specification that engine requires—not just whether a listing says “Equinox.”

These seven options include iridium and platinum plugs, four- and six-packs, and kits with ignition coils. Use the guide below to narrow the field before checking exact fitment.

Best 7 Spark Plugs for Chevy Equinox Picks for 2026

Six-Plug 41-109 Option – SYKRSS Iridium 41-109 Six-Pack

When shopping for spark plugs for Chevy Equinox models, start with the engine and OE part number—not just the vehicle name. This SYKRSS six-pack references 41-109, 12622561, 12681660, and ILTR6E11, and lists Equinox among its compatible vehicles.

Best For: Buyers replacing a six-plug set who have confirmed that 41-109 or ILTR6E11 matches their Equinox application.

Pros:

• Includes six iridium plugs and a manual.
• Lists several OE reference numbers for fitment checks.
• Includes a one-year manufacturer warranty.

Cons:

• The broad compatibility list does not clearly identify an Equinox year and engine for this set.
• Six plugs may be the wrong quantity for a four-cylinder Equinox.

This is worth considering if your parts lookup confirms both the 41-109 specification and a six-plug requirement. Verify fitment before ordering rather than relying on the broad vehicle list.

1.5L Iridium Match – BDFHYK 91970 Four-Pack

For shoppers comparing spark plugs for Chevy Equinox 1.5L four-cylinder models, this BDFHYK four-pack offers a specific fitment starting with the 2018 model year. Its listing references 91970, ILNAR8B7G, and 90644; check your exact year and OE number before buying.

Best For: Owners of a listed 2018–2024 Equinox 1.5L seeking a four-plug iridium set with matching OE references.

Pros:

• Four-plug quantity suits the listed four-cylinder application.
• Fine iridium center electrodes and ceramic insulators are specified.
• Includes a one-year warranty.

Cons:

• Not listed for Equinox engines other than the 1.5L.
• The title ends at 2023, while the compatibility notes include 2024; verify 2024 fitment carefully.

The engine-specific listing makes this easier to evaluate than a generic Equinox set. Match the OE number as well as the year and engine, particularly for a 2024 vehicle.

Earlier 2.4L Choice – NGK G-Power Platinum LTR5GP Four-Pack

If you need spark plugs for Chevy Equinox LT models with the 2010–2014 2.4L four-cylinder engine, this NGK G-Power listing is unusually specific about its application. It supplies four LTR5GP platinum-tipped plugs rather than the iridium plugs used in the other sets here.

Best For: Owners of a 2010–2014 Equinox LT 2.4L who want the listed NGK platinum four-pack.

Pros:

• Identifies the Equinox LT year range and 2.4L engine.
• Fine-wire platinum center electrodes are designed to reduce required ignition voltage.
• Copper cores aid heat removal; trivalent plating resists corrosion and seizing.

Cons:

• Its stated fitment is limited to the 2010–2014 Equinox LT 2.4L.
• Platinum construction is not an iridium option if that is the specification you need.

Choose this set for its clearly stated older 2.4L application, but confirm the plug number against your vehicle before installation. Do not assume it fits other Equinox engines or model years.

91970 Reference Alternative – A-NAFTULY Iridium Four-Pack

This four-pack is another option among spark plugs for Chevy Equinox 1.5L four-cylinder applications. The listing identifies 2016–2024 Equinox 1.5L fitment and references 91970, ILNAR8B7G, 90644, 12683541, and 55490097, giving you several numbers to compare with your vehicle’s required plug.

Best For: Buyers with a confirmed Equinox 1.5L application matching the listed 91970-family reference numbers.

Pros:

• Includes four iridium plugs with 0.6 mm fine-wire center tips.
• Provides five reference numbers for cross-checking.
• Lists a 12-month warranty.

Cons:

• The broad 2016–2024 Equinox range should be checked against the exact year and engine.
• Not listed as a fit for Equinox engines other than the 1.5L.

The multiple reference numbers are useful for narrowing down compatibility, but they do not replace an exact vehicle lookup. Confirm the required plug and four-plug quantity before purchasing.

1.5L Coil-and-Plug Kit – UF802 Iridium-Platinum Set

If you’re shopping for spark plugs for Chevy Equinox models with the 1.5L engine, this kit pairs four iridium-platinum plugs with four UF802 ignition coils. The listed Equinox fitment is 2018–2021; confirm your vehicle details before ordering.

Best For: Equinox 1.5L owners replacing coils and plugs together.

Pros:

• Includes four coils and four spark plugs for a combined replacement.
• Lists fitment for 2018–2021 Equinox 1.5L models.
• Plugs feature iridium-platinum electrodes and high-alumina ceramic insulation.

Cons:

• Not listed for Equinox engines other than the 1.5L.
• Only a 90-day manufacturer warranty is specified.

Choose this kit when both ignition components need attention; if your coils are working well, a plugs-only set may be more appropriate. Check year and engine fitment before purchase.

Plugs-Only Pick – WJAUTO Pre-Gapped Iridium 4-Pack

For shoppers seeking spark plugs for Chevy Equinox vehicles without replacing ignition coils, this WJAUTO set offers four pre-gapped iridium plugs. The listing names 2010–2017 Equinox models, but verify your exact year and engine before buying.

Best For: Owners who need a four-plug tune-up rather than a coil-and-plug kit.

Pros:

• Four plugs cover a four-cylinder replacement.
• Factory pre-gapped for easier installation.
• Manufacturer states a service life of up to 80,000 km.

Cons:

• No ignition coils are included.
• The listing describes both a four-pack and a 24-pack, so confirm the quantity before checkout.

This is the simpler option when your existing coils do not need replacement. Because the quantity wording conflicts within the listing, check the selected package as well as vehicle fitment.

2.4L Coil-and-Plug Kit – UF491 Iridium Set

Among spark plugs for Chevy Equinox 2.4L models, this UF491 kit is geared toward a broader ignition refresh: it includes four iridium plugs and four coil packs. Its stated Equinox fitment is 2010–2017 with the 2.4L four-cylinder engine.

Best For: Equinox 2.4L owners replacing all four coils and plugs at once.

Pros:

• Combines four coils and four plugs in one kit.
• Specifically lists 2010–2017 Equinox 2.4L fitment.
• Plugs feature laser-welded electrodes and high-alumina ceramic insulation.

Cons:

• Not listed for Equinox engines other than the 2.4L.
• Only a 90-day manufacturer warranty is specified.

This kit makes sense when you intend to replace both components, not just worn plugs. Verify the year, engine and part fitment before ordering.

How We Picked the Best Spark Plugs for Chevy Equinox

We focused on the differences that matter most when shopping for Spark Plugs for Chevy Equinox models: listed vehicle and engine fit, plug construction, pack quantity, and whether ignition coils are included. The selection covers several Equinox engine applications rather than treating every model year as interchangeable. Listing claims are a starting point, not proof of fit; confirm the part number against your vehicle before buying.

Quick Comparison

Start with your engine, then compare what comes in the box. The BDFHYK 91970 four-pack specifically lists the 2018–2023 1.5L application, while the NGK G-Power Platinum LTR5GP four-pack lists 2010–2014 2.4L LT models. The 41-109 ILTR6E11 option is a six-pack, which may suit an application requiring six plugs. Other four-packs in the roundup list broader GM vehicle coverage; verify their exact engine and year compatibility rather than relying on that broad description. The UF802 and UF491 sets add ignition coils for shoppers who need both components, but those kits serve different listed applications.

Key Buying Factors for Spark Plugs for Chevy Equinox

Engine Fit Comes First

Check your Equinox’s model year, engine displacement, and cylinder count, then match the plug’s exact part number to the owner’s manual, an OEM parts catalog, or a reliable fitment lookup. Similar-looking GM plugs can differ in reach, heat range, thread dimensions, and electrode design. A pack with the right number of plugs is not necessarily the right plug.

Electrode Material and Gap

Choose a plug that meets your engine’s specified design rather than assuming iridium is always an upgrade over platinum. Some listings describe plugs as pre-gapped, but shipping and handling can affect the gap. Check it against the specification for your engine, and follow the plug maker’s instructions when measuring or adjusting fine-wire electrodes.

Quantity and Coil Kits

Match pack size to the number of cylinders you are servicing. Four-packs and six-packs are not substitutes for one another. A plug-and-coil kit can be convenient if coils also need replacement, but new plugs alone do not diagnose a misfire. Check trouble codes and inspect the ignition system before paying for additional parts.

Who Should Buy Which Spark Plugs for Chevy Equinox?

If you have a 2018–2023 1.5L Equinox, begin with the listing that names that application and verify its 91970 specification for your exact vehicle. For a 2010–2014 2.4L LT, the listed NGK platinum four-pack is a fitment lead worth checking. Consider a six-pack only if your verified engine application calls for six matching plugs. Choose a UF802 or UF491 coil-and-plug set when its components match your vehicle and you have a reason to replace the coils. For every option, exact fitment matters more than a broad “fits Chevy Equinox” claim.
