APR Iridium Pro Spark Plugs

Featuring one of the strongest available materials for this type of product, APR Iridium Pro spark plugs help provide an ideal upgrade for tuned engines. They run cooler, resist pre-ignition, last longer than other materials with higher melting points, and require less voltage to produce a strong spark. The electrode is harder and stronger than other materials; can dissipate heat more easily; and is better protected from melting, cracking and other limitations found with standard models. These plugs are designed for use on tuned and high-performance vehicles that benefit from a 'cold' plug. They also pair nicely with APR ignition coils, where applicable. Order the APR Iridium Pro spark plugs recommended for your vehicle. Other features include: * Heat range 9 (similar to Bosch 3, Brisk 10, Denso 27, and NGK 9 ranges) * Melting point is higher than platinum (38 percent), copper (125 percent) and silver (152 percent) * Available in non-projected and projected insulator designs * Optimized electrode design for hard-to-ignite fuels (ethanol, etc.)

NGK Laser Platinum Spark Plugs

These double platinum NGK laser platinum spark plugs feature laser-welded technology. Lasers are used to pinpoint precision welds, reducing excess debris. The reduction of debris decreases the required voltage to bridge the spark gap. Platinum disks welded on the ground and center electrodes reduce the wear rate on both of these surfaces, ensuring great durability and long life.

Autolite Copper Core Spark Plugs

Autolite copper core spark plugs feature a cold-formed steel shell with precision-rolled threads, a full copper core electrode for better performance, and a one-piece terminal post to add strength. The ignition plugs use a copper-glass seal that bonds the insulator and terminal post center electrode together. This ensures full voltage at the spark gap and a 100 percent leak-proof, gas-tight seal. Autolite features an extensive application guide to cover just about everything with an internal combustion engine. Keep your engine running smoothly and reliably with Autolite replacement copper core spark plugs.

Bosch EVO Spark Plugs

Bosch EVO spark plugs are engineered to ensure reliable ignition throughout their long service life, even under extreme conditions in modern engines. Thanks to an improved insulator design and high dielectric strength (greater than 45 kV), the new EVO spark plugs can withstand irregular combustion—known as mega knocking—that can occur in modern, technologically advanced engines. These plugs are developed and produced with the same high quality as original equipment spark plugs. Today's turbocharged gasoline direct injection engines place high demands on spark plugs; Bosch EVO meets these needs. Additional product details: * Long service life: The iridium alloy in the firing pin of the center electrode and platinum-iridium alloy on the ground electrode reduces the wear on the electrodes and increases the service life of the spark plug * Mechanical strength: Improved design features on the insulator and housing increase the head bending strength, reducing risk of damage during installation and optimizing gas seal tightness in the cylinder head * Corrosion defense: Improved corrosion protection through the use of a process developed by Bosch for nickel coating of the spark plug housing * Thermomechanical strength: Improved insulator design features provide greater resistance to irregular burns and mega-knocking * Center electrode core material: Nickel-chromium-iron and copper * Center electrode tip material: Iridium * Ground electrode core material: Copper * Ground electrode tip material: Platinum and nickel-chromium-iron and copper
