Best Gas Spark Plugs of 2026

The NGK G-Power Platinum Spark Plugs TR5GP is designed to operate over a wider heat range than ordinary plugs, resist carbon buildup, and pre-ignition. The patented triple gasket sealing process eliminates the possibility of combustion gas leakage, ensuring reliable performance.

The NGK Iridium IX Spark Plug is designed for performance enthusiasts, offering improved throttle response, anti-fouling, and extreme ignitability. The spark plug features a 0.6mm laser-welded fine iridium tip that ensures high durability and consistent, stable sparks. A tapered ground electrode helps minimize the electrical quenching effect, while a longer insulator nose prevents fouling. The spark plug also has superior anti-corrosion and anti-seizing properties thanks to its trivalent metal plating.

The NGK LKR7DIX-11S Iridium IX Spark Plug is designed for performance enthusiasts, offering extreme ignitability and improved throttle response. Its laser-welded fine Iridium tip ensures high durability and a consistently stable spark, while the tapered ground electrode minimizes electrical quenching effect. The corrugated ribs on the longer insulator prevent flashover, and the triple gasket seal eliminates combustion gas leakage. The Iridium alloy has an extremely high melting point, making it durable to heat and electrical wear, perfect for high-performance engines. The Trivalent Metal Plating provides superior anti-corrosion and anti-seizing properties.

NGK Spark Plugs TR55 is designed to work in a wider heat range, resist carbon buildup, and eliminate the possibility of combustion gas leakage with its patented triple gasket sealing process. It has been a reliable OE cornerstone for decades.

NGK 6619 Iridium Spark Plugs are designed to operate over a wider heat range than ordinary plugs, resist carbon buildup and pre-ignition, and eliminate the possibility of combustion gas leakage with its patented triple gasket sealing process. These spark plugs are ideal for anyone who wants a durable and reliable option for their vehicle.

The NGK BPR6EFS Plug is designed to handle a wider range of temperatures than typical spark plugs, which means it can perform well in various driving conditions without overheating or fouling. It also helps prevent carbon buildup and early ignition, so your engine runs smoother and more efficiently. The plug uses high-quality alumina ceramic material that improves heat transfer and keeps the electrical parts well insulated, ensuring consistent performance. Additionally, its solid copper core and nickel-tipped electrode extend the plug's lifespan, so you don’t have to replace it as often, saving you time and money.

The ACDelco Professional Platinum Spark Plug offers a one-piece, gas-tight seal and a double platinum point pad that provides consistent voltage demands, prevents wear on the ignition system and protects against compression pressures. With pure copper core, this spark plug can maximize durability and reduce fouling resistance. Formerly known as ACDelco GM Original Equipment parts.
