Advance Auto Spark Plugs Are a Common Aftermarket Choice, But Quality and Fit Vary by Brand

Advance Auto Parts carries multiple spark plug brands at different price points, not a single "Advance Auto" brand. The store stocks OEM replacements for most vehicles, along with aftermarket options from manufacturers like Champion, Bosch, and ACDelco. Which one you buy matters because spark plugs vary in heat range, electrode material, and lifespan — and the wrong choice can cause misfires, poor fuel economy, or engine damage.

When you walk into an Advance Auto store or order online, you are choosing between OEM plugs (made by your vehicle's manufacturer) and aftermarket plugs (made by third-party companies). OEM plugs match your engine's original specifications exactly. Aftermarket plugs may cost less upfront but can differ in durability, performance, and how long they last before replacement.

The real decision is not "Advance Auto or somewhere else" — it is which brand and type of plug to buy, and Advance Auto carries enough variety that you can make that choice there. Understanding what those differences mean will save you money and prevent engine problems.

Key Takeaways

  • Advance Auto Parts stocks OEM spark plugs for most vehicles, which match your engine's original specifications and are the safest choice if you are unsure what to buy.
  • Aftermarket brands like Champion, Bosch, and ACDelco are cheaper than OEM but vary in lifespan and performance, so comparing the warranty and heat range matters.
  • Spark plug heat range (the number on the plug) must match your engine — using the wrong range causes misfires or overheating and cannot be corrected by switching brands.
  • Most spark plugs last 30,000 to 100,000 miles depending on type, so a cheaper plug that needs replacement sooner may cost more over time than a pricier one.
  • Your vehicle's owner manual or the parts counter at Advance Auto can tell you the correct plug type, heat range, and gap for your specific engine.

OEM Versus Aftermarket Spark Plugs at Advance Auto

OEM spark plugs are made by the same manufacturer that built your engine — Toyota plugs for a Toyota, Ford plugs for a Ford, and so on. Advance Auto can order OEM plugs for most vehicles, though they may not stock every OEM option in the store. OEM plugs cost more per unit but are engineered to your engine's exact specifications and carry the manufacturer's warranty.

Aftermarket plugs are made by independent companies and sold under their own brand names. Advance Auto stocks Champion, Bosch, ACDelco, and others. These plugs are cheaper — often 40 to 60 percent less than OEM — but they are not all the same. A Champion plug rated for 30,000 miles will cost less than a Bosch plug rated for 100,000 miles, and the difference in total cost over time depends on how often you are willing to replace them.

Neither choice is wrong, but the trade-off is clear: OEM plugs cost more upfront and last as long as the manufacturer designed them to. Aftermarket plugs cost less upfront but may need replacement sooner, and you are betting that the brand you choose will perform as advertised. If you have never replaced spark plugs before, OEM is the safer bet because it removes the guesswork.

Heat Range and Spark Plug Gap Matter More Than Brand

Every spark plug has a heat range — a number that tells you how hot the plug runs inside your engine. A plug that is too cold will foul (collect carbon deposits) and misfire. A plug that is too hot will overheat and damage the engine. Your vehicle's manual specifies the correct heat range, and using the wrong one will cause problems no matter which brand you buy.

The gap is the space between the center electrode and the ground electrode — the distance the spark has to jump. Advance Auto can set the gap for you before you leave, or you can do it yourself with a gap tool. If the gap is too wide, the spark will not jump and the plug will not fire. If it is too narrow, the spark will be weak. Most modern plugs come pre-gapped, but it is worth checking the manual to be sure.

When you go to Advance Auto, bring your vehicle's year, make, model, and engine size. The parts counter can look up the correct heat range and gap in seconds. If you order online, the website will ask for this information and show you only plugs that fit your engine. Buying the wrong heat range is one of the most common mistakes people make, and it costs more to fix than it would have cost to get it right the first time.

Spark Plug Lifespan and Total Cost of Ownership

A cheap spark plug that lasts 30,000 miles will need replacement three times before a premium plug rated for 100,000 miles needs replacement once. If the cheap plug costs $5 and the premium plug costs $15, you will spend $15 total on cheap plugs versus $15 on the premium plug — but you will also spend time and labor three times instead of once. If you are paying a mechanic to install them, labor costs can exceed the cost of the plugs themselves.

Advance Auto's website and in-store displays usually list the expected lifespan for each plug. Standard copper plugs typically last 30,000 to 50,000 miles. Platinum plugs last 60,000 to 100,000 miles. Iridium plugs last 100,000 to 150,000 miles. The material in the electrode affects how long it resists erosion, and that is why iridium costs more upfront.

Calculate the cost per mile, not just the price per plug. A $20 plug that lasts 100,000 miles costs $0.20 per 1,000 miles. A $5 plug that lasts 30,000 miles costs $0.17 per 1,000 miles — cheaper, but only if you do not count the time and labor to replace it three times. For most drivers, a mid-range plug (platinum or iridium) from a known brand balances cost and durability.

How to Find the Right Spark Plug at Advance Auto

Start with your owner's manual. It lists the OEM spark plug part number, heat range, and gap. Write down this information or take a photo of the page. When you go to Advance Auto — in person or online — give the parts counter your vehicle's year, make, model, and engine size. They will cross-reference the OEM part number and show you OEM options and compatible aftermarket options.

If you do not have the manual, Advance Auto's website has a "Find Parts" tool where you enter your vehicle information and it returns a list of compatible spark plugs. The tool filters by price, brand, and lifespan, so you can compare options side by side. Each listing shows the heat range, gap, and warranty. Read the warranty carefully — some plugs are warranted for a set number of miles, others for a set number of years.

Do not rely on the store employee to know your engine's requirements unless you have verified them yourself first. Mistakes happen, and installing the wrong plug can damage your engine. Spend five minutes confirming the part number before you buy, and you will avoid a costly mistake.

Installation and When to Replace Spark Plugs

Spark plugs are one of the few engine parts a DIY mechanic can usually replace without special tools. Most vehicles require only a spark plug socket, a ratchet, and a gap tool. Advance Auto sells all three, and YouTube videos show the process for your specific vehicle. If you are not comfortable working on engines, a mechanic can install them for $50 to $150 per hour, depending on how many plugs your engine has and how hard they are to reach.

Replace spark plugs when your engine misfires (hesitates or stumbles under acceleration), when the check engine light comes on with a misfire code, or when you reach the mileage interval in your manual. Some vehicles need spark plugs every 30,000 miles; others go 100,000 miles or more. Waiting until you have a problem is cheaper than replacing them on a schedule, but it risks engine damage if a plug fails completely.

Advance Auto can scan your vehicle's diagnostic codes for free in most locations. If the code points to a spark plug misfire, you know which cylinder is the problem and can replace just that plug or all of them at once. Replacing all plugs at the same time is usually smarter because if one is worn, the others are likely worn too.

Frequently Asked Questions

Can I use any spark plug brand as long as the heat range is correct?

Heat range is the most important factor, but brand matters for durability and warranty. A Champion plug and a Bosch plug with the same heat range will both fire correctly, but they may last different lengths of time. Stick with a known brand from Advance Auto's inventory, and you will have recourse if the plug fails early.

What does the warranty on a spark plug cover?

Most spark plug warranties cover defects in materials or workmanship — a plug that fails to fire or breaks inside the engine. They do not cover damage caused by using the wrong heat range, installing the plug incorrectly, or running an engine that is out of tune. Bring the receipt and the failed plug to Advance Auto if you need to make a warranty claim.

Is it cheaper to buy spark plugs at Advance Auto or at a dealership?

Advance Auto is usually cheaper for the plugs themselves, especially aftermarket options. A dealership will charge more for OEM plugs and significantly more for labor. If you are installing them yourself, Advance Auto is the better deal. If you are paying for installation, get quotes from both places because labor rates vary.

Do I need to replace all spark plugs at once or just the bad one?

Technically you can replace just one, but if one plug is worn enough to cause a misfire, the others are likely worn too. Replacing all of them at once costs more upfront but saves you from returning to the job in a few thousand miles. Most mechanics recommend replacing the full set.

What happens if I use the wrong heat range spark plug?

A plug that is too cold will foul and cause misfires. A plug that is too hot will overheat and can damage the engine. Either way, you will notice hesitation, rough idle, or a check engine light. The plug will not damage the engine when ready, but running on a wrong plug for thousands of miles can cause problems. Replace it with the correct heat range as soon as you realize the mistake.
