About the Autolite Double Platinum Spark Plug Line

The Double Platinum Spark Plug line from Autolite features spark plugs with platinum on both the center and ground electrodes. This design enhances electrode longevity and maintains consistent spark performance over time. The APP5364 model benefits from this technology, providing reliable ignition and reduced electrode wear compared to conventional spark plugs.

Technical Details and Compatibility

The APP5364 spark plug incorporates a tapered ground electrode tip made of platinum with a nickel core, paired with a platinum center electrode. The ceramic insulator is mid-projection type, aiding in heat management and electrical insulation. With a resistor value of 4000 ohms, this spark plug helps minimize radio frequency interference. It is compatible with various models such as the Buick LaCrosse, Cadillac ATS, Chevrolet Malibu, Ford Focus, Mazda MX-5 Miata, and Mercury Cougar, among others.

Common Applications and Problem Solving

• Restores engine misfire issues caused by worn or fouled spark plugs
• Improves fuel efficiency by ensuring consistent ignition
• Reduces ignition system electrical noise with built-in resistor
• Extends spark plug service life in vehicles with moderate to high mileage
• Supports smooth engine start and idle stability

Installation Notes and Tips

• Verify compatibility with your vehicle’s make and model before installation
• Use a torque wrench to tighten to manufacturer specifications to avoid damage
• Check and adjust spark plug gap if necessary, though pre-gap is set at 0.054 inches (1.40 mm)
• Inspect ignition components for wear during replacement
• Handle spark plugs carefully to avoid damaging the ceramic insulator
