Autolite Platinum spark plugs are crafted for exceptional performance and durability, making them ideal for older engine applications. Featuring a platinum center electrode firing tip, these spark plugs ensure quicker firing, smoother starts, and enhanced acceleration while boosting fuel efficiency. The platinum firing tip prevents gap erosion, extending the service life, while the high alumina ceramic insulator offers superior thermal conductivity and insulation for added strength. A multi-rib insulator design prevents flash-over, ensuring reliable operation, and the nickel-plated shell resists corrosion for long-lasting durability. With a mid-projection standard center electrode and a tapered seat type, these performance-grade spark plugs deliver consistent results. The combination of platinum and nickel materials in the electrode tips further enhances reliability, making them a smart choice for drivers seeking improved engine efficiency and extended part longevity.

BOSCH OE Fine Wire Double Iridium. All iridium plugs are NOT created equal. Give your customers the only one engineered for both high performance and long life. The ultra fine wire design and laser welded, tapered ground electrode deliver the ultimate in ignitability and high performance. The iridium-alloy center electrode firing pin and laser welded ground electrode with iridium alloy inlay help it to go the distance.

Double Platinum Spark Plug (PQ16R) delivers exceptional performance and reliability, meeting the strictest OE standards for durability and emissions. Featuring OE-grade platinum on both the center and ground electrodes, this spark plug ensures sustained spark performance for over 60,000 miles, making it a long-lasting solution for your vehicle’s ignition system. Its premium shell construction with machine-rolled threads enhances durability and ensures a secure fit, while superior thermal conductivity optimizes heat dissipation for consistent performance. Designed with reduced secondary required voltage, it increases ignition efficiency, providing smoother engine operation and reducing the likelihood of shop comebacks. The flat seat type ensures compatibility with a wide range of vehicles, while the double platinum design guarantees reliable performance under demanding conditions. This spark plug is a smart investment for drivers seeking enhanced ignition efficiency and long-term value.

ACCEL’s patented race proven spark plugs in a Shorty configuration. The overall length has been reduced 3/16 in to 3/8 in (depending on the specific spark plug) to gain critical air gap between the spark plug boot and the exhaust manifold or header tube. This helps eliminate burning the spark plug boot or dimpling the header tube. The shorter spark plug length also can make it easier to install an remove the spark plugs in certain applications where there is not a lot of room to fit a socket or move a wrench around. ACCEL Shorty Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire. ACCEL Shorty Spark Plugs are gapable allowing you to open the gap exposing a larger flame kernel or close it if needed for high boost applications. All ACCEL Shorty Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.
