ACDelco Gold Automotive AGM Batteries

ACDelco Gold Automotive AGM batteries have high-cycling capabilities, are remarkably charge-receptive, and are necessary for start/stop applications. These batteries are also maintenance-free, 100 percent pressure-tested against leaks, and are manufactured to resist corrosion. Best of all, they are backed by ACDelco's outstanding warranty coverage. When reliable starting power is a priority— ACDelco Gold Automotive AGM batteries are the answer! Additional features include: * Absorbed Glass Mat design is 100 percent leak and spill-proof, because the electrolyte is permanently held in the glass mat separator, instead of free flowing within each cell * Oxygen recombination reduces water loss and reassures maintenance-free performance * ACDelco Gold Automotive AGM batteries have longer life expectancy in traditional vehicle applications, due to a maintained pressure on the plates, which significantly reduces the amount of active mass lost from the grid

Mishimoto Ignition Coils

The basic requirements for a properly running engine are fuel, air, compression, and spark. A weak spark from your ignition system can result in misfiring under high-load driving, and spark blow-out under high boost, which is bad for performance. Mishimoto ignition coils are high-quality replacements that can bring your vehicle up to Stage 0 before moving on to horsepower adding modifications. They are designed and tested to meet or exceed OEM performance standards and are available as a single coil or in sets. Once installed with a set of new spark plugs, you can expect a refreshed ignition system with improved engine startup, a smoother idle, and restored performance. The primary frame of Mishimoto coils is constructed from extremely robust phenolic resin, ensuring optimal longevity in high-temperature environments, while a precision lower rubber boot provides a barrier against moisture entry into the plug well, eliminating chances for spark plug contamination. Each coil is pre-lubricated with dielectric grease to prevent corrosion and ensure an optimal connection between the spark plug and coil. Swap out your worn or defective factory coils with Mishimoto's ignition coils, and as with all their products, the coils include their signature Mishimoto Lifetime Warranty. Choose the ones designed for your vehicle in the quantity needed.

Standard Motor Mass Airflow Sensors

Standard Motor mass airflow sensors are higher quality, precision alternatives to remanufactured models. MAF sensors measure the amount of airflow entering the intake manifold and must communicate clearly with your vehicle's Engine Control Module (ECM). Remanufactured components with debris from prior use can hinder this communication and cause your vehicle to experience drivability issues. With many new—not remanufactured—MAF sensors in the Standard lineup, they cover more than 90 percent of all MAF-equipped vehicles, and all are airflow-calibrated to ensure accuracy. SMP-manufactured sensors are designed with improvements such as thicker walls, upgraded components, and a custom-designed platinum RTD sensor. The result is a line of MAF sensors that provide highly accurate readings and precise airflow output under all operating conditions. Order the model designed for your car, truck, or van.
