There’s many fixes and repairs on a car that can be difficult and tedious. Changing your spark plugs is typically not one of them. Despite the fact that it’s an easy fix, that doesn’t mean that people want to have to replace their spark plugs.
Ideally, a car should have a reliable, high performance spark plug with some staying power. A good spark plug can improve both fuel economy and performance of an engine!
So who makes the best spark plugs? When choosing one, it’s important to keep in mind that not every spark plug is going to fit onto every vehicle. Always ensure you are choosing one that fits the engine. If you’re ordering online, there will likely be a tool that can ensure the spark plug in question will fit into your vehicle. In addition, make sure that the spark plugs are pre-gapped if you don’t know what “gapping” is when you’re changing spark plugs. (It’s about the space between electrodes) The following are all excellent spark plugs and a great choice if they fit your engine of choice.
1 - NGK 6619 Iridium Spark Plug
NGK is a performance brand that is going to make more than one appearance on this list for sure. Iridium spark plugs are always an excellent choice because of the metal they are made from. Unlike older spark plugs, iridium alloys feature a higher melting point. This means that the spark plugs are going to be more durable and work very well in a high performance setting. Good spark plugs cost money however. These run $40 for a set of 6. They aren’t the most expensive, but they certainly aren’t the least. When it comes to gapping, they are not advertised as gapped. Many people have used them directly from the box and stated that they are actually excellently calibrated despite the lack of advertisement.
2 - Denso PK20TT Platinum TT Spark Plug
When it comes to consistency and durability, there’s not a whole lot of plugs out there that can beat this Denso product. Unlike many of the others on this list, there’s absolutely no frills with this spark plug. It will do its job in a steady workmanlike fashion, and it will do it right for a long time. In addition to being stable, they are relatively cheap as well. These can be found for about $2.50 per spark plug at various retailers.
3 - NGK 3403 G-Power Platinum Spark Plug
If you’re driving a ford, lincoln or buick, this may be the spark plug for you. Using platinum rather than Iridium, these spark plugs do a great job at increasing power and increasing fuel economy. These plugs come gapped and ready to go right out of the box. Coming in at $20 for a six pack, the price point is quite reasonable as well.
4 - Bosch 4417 Platinum+4 Spark Plug
One of the benefits of these spark plugs is that they fit a really large number of vehicles. In addition to being durable, they also do a good job of keeping combustion efficient and effective. This Bosch product comes in at around $5 per spark plug from most retailers, making it a solid economical option.
5 - Autolite HT15 Platinum High Thread Spark Plug
This spark plug is intended almost specifically for large 3-valve Ford motors. The plugs are known for being incredibly durable during use, but sometimes they have issues during installation.
