Best Spark Plugs for Toyota Camry 2007

 Even the most durable spark plug will wear down over time from regular use. While some can last a decade or more, if your car’s a 2007 you’ll probably need to replace the spark plugs at some point. Aside from regular wear and tear, spark plugs can also become fouled by engine misfires, dirty oil, or other combustion system problems. Even if your spark plugs are newer than your car, there’s no guarantee they’re still operating at peak efficiency.

Changing out spark plugs isn’t difficult. The first step is to buy the right ones for your car. Some spark plugs are designed to provide more power than others, so you don’t just want to grab the first ones you find.

Our top choices for the best spark plugs for a 2007 Toyota Camry are both from NGK—the NGK Laser Iridium Spark Plug for 3.6L V6 engines and the NGK Iridium IX Spark Plug for 2.4L L4 models. Some users might want a different kind of performance from their engine, though—and that’s why we’ve included a selection of options below.

Even within the category of Toyota Camrys, there are two different engine sizes: the 3.5L V6, and the 2.4L L4. Let’s look at the most important factors you want to consider when you’re shopping.

Size

This one might seem obvious, but it’s the first thing you should check. Before you buy a spark plug, you want to make sure it will fit into your engine correctly. A loose spark plug or spark plug wire will trigger a host of engine trouble codes, and may even prevent your vehicle from starting.

You can find your Camry’s spark plug specifications in your manual. Only get spark plugs that match these measurements exactly for the best performance. All of the spark plugs reviewed here are sized to fit correctly in a 2007 Toyota Camry.

Durability

A spark plug’s durability is primarily a factor of the metal used for the electrodes. The spark your spark plugs generate runs between the center electrode and the side electrode. Over time, both will wear down, losing their sharp edge. This makes it more difficult for the spark to generate.

Metals that are harder and have a higher melting point retain their sharp edge longer. The nickel alloy electrodes used in copper spark plugs are the least durable; metals like iridium and platinum last longer, especially in high-performance engines.

Power

The more spark the plug produces, the more combustion power it provides. Keep in mind a bigger spark isn’t always better. Just like the spark plug’s size, it’s about matching the plug to your engine, maximizing its efficiency. A spark plug that produces more power can increase your engine’s horsepower in some situations. Keep in mind these boosts in power will be minor—an increase of 1-2%, in most cases.

Vehicles that are already high-performance models (like the 3.5L version of the 2007 Toyota Camry) are already designed with the most efficient spark plugs. Replacing worn spark plugs can give you a noticeable boost, but in reality, you’re just restoring your engine to its original optimum performance.

Bosch 9615 Double Iridium 

Bosch 9615

Double spark plugs use an extra layer on the side electrode to increase efficiency over traditional designs. Paired with the highly durable iridium, this makes the Bosch 9615 Double Iridium Spark Plug an excellent choice if you’re looking for the plugs that will last the longest.

Even though these plugs are durable once you get them in your car, they’re a bit more delicate when you’re handling them. Several buyers report them breaking during installation, which is the only negative we can see with these Bosch spark plugs. So long as you’re careful putting them in, they can last up to 7 years in your engine.

These Denso Iridium TT Spark Plugs are ideal if you drive hard. They hold up for years even in racing vehicles, so you know you can count on them to get you to work and back consistently. Our only quibble with the design is that the casing isn’t as durable as some we’ve seen. You may want to check periodically for rust or use an anti-corrosion treatment if you live in a wetter climate.


NGK (6176) DILFR6D11

NGK 6176

Here’s another great option if you’re looking for maximum power the NGK Laser Iridium Spark Plug. Their method of welding increases the durability of the center electrode and lets the plug provide a more powerful spark. This translates to both a longer usable life and better overall performance.

You can use them in any driving conditions without a worry, and that’s great for people who drive in harsh climates.

The only thing to look out for with these NGK spark plugs is that, while they are pre-gapped, they don’t always arrive gapped correctly for a 2007 Toyota Camry. Make sure you check them before you install them in your engine.

These Toyota spark plugs are fairly durable. They’re platinum, which lasts longer than copper plugs, but not quite as long as iridium. They’ll last 5-6 years for most people.

The NGK Laser Iridium Spark Plug is an exceptional value, first of all, providing a laser-welded iridium tip for less than platinum spark plugs from other manufacturers. The platinum disc welded onto the ground electrode extends the life of this spark plug. Like other NGK products, it also uses a plating of trivalent metal with a triple seal. This means it won’t seize or corrode, and you never have to worry about gas leaks.

The NGK Laser Iridium Spark Plug also delivers when it comes to power. The quick acceleration response is noticeable, and you’ll also likely see improvements in your gas mileage and emissions after they’re installed. Top to bottom, this is the best replacement spark plug for a 2.4L 2007 Toyota Camry if you’re looking for value. It performs on-par with other high-quality spark plugs, but at a lower cost.


Gap Size: Does It Matter?

Gap size describes the distance between the center electrode and the side electrode. On most spark plugs, you can adjust the gap size using a gapping tool. But since it’s not a set measurement, does it matter when you’re shopping for spark plugs?

For your engine’s performance, the size of the gap matters a lot. If the gap is too close, the spark between the electrodes won’t be large enough to ignite the fuel properly. If the gap is too wide, the spark can’t reach, and the plug won’t fire.

The majority of spark plugs are sold pre-gapped. In other words, the side electrode is positioned for optimal efficiency when they leave the factory. In some cases, however, spark plugs do need to be gapped before installation.

Gapping tools are inexpensive, but the gap size must be precise. For this reason, it’s best to buy pre-gapped spark plugs if you’re a relative novice in the garage. 

So What’s the Best Spark Plug for Toyota Camry (2007)?

Ultimately, the easiest way to make sure that you’re installing the correct spark plugs is to use the exact type recommended in your vehicle’s manual. With an older car, however, you may not be able to find that specific make in your local auto shop.

Even an expensive spark plug won’t cost you more than twenty bucks. Don’t choose a cheaper spark plug based on price if you’re not certain it’s right for your engine. Using the wrong spark plugs can cause misfires. Damage from misfires can cost a lot more to fix than the few bucks you saved. The only reason you should intentionally change from the original spark plugs is to adjust how your engine runs, using one that is “hotter” or “cooler” to alter the performance.

Understanding the differences between spark plugs will help you choose the right ones for your vehicle. You can count on any of the options above to fit in a 2007 Toyota Camry, and give you the performance that you’re looking for. Hopefully, this article has helped you better understand your Camry’s spark plug needs!
