ACDelco Professional Platinum Spark Plugs (8 Pack)

The one-piece, fired-in suppressor seal blends three distinct glass types to create a gas-tight seal. This design helps to mitigate radio frequency and engine interference, regulate spark plug energy, and safeguard against compression pressures, ultimately contributing to extended lifespan.

Moreover, the double platinum point pad on both the center and ground electrodes offers excellent durability and consistent voltage demands, which in turn helps reduce wear on the ignition system.

Furthering the enhanced performance, the pure copper core results in a cooler electrode temperature, maximizing durability and fouling resistance.

It is worth noting that some ACDelco GM Original Equipment parts may have previously been marketed under the ACDelco Professional brand.

The strategic combination of the gas-tight seal, durable electrode design, and optimized core material collectively contribute to the exceptional performance and longevity of these spark plugs. The gas-tight seal's ability to mitigate interference and protect against compression pressures ensures reliable ignition, while the platinum point pads and copper core work in tandem to maintain consistent voltage demands and minimize electrode wear, ultimately extending the spark plug's lifespan.

This integrated approach to spark plug engineering exemplifies ACDelco's commitment to providing Original Equipment quality parts that meet the exacting standards of General Motors vehicles. By blending cutting-edge materials and innovative design, ACDelco spark plugs deliver a level of performance and reliability that helps vehicle owners maximize the efficiency and longevity of their engines.

Whether it's the one-piece suppressor seal, the durable electrode construction, or the heat-dissipating copper core, each component of the ACDelco spark plug is meticulously engineered to meet the demands of modern automotive engines. This attention to detail and focus on quality is a hallmark of the ACDelco brand, ensuring that their parts provide the reliable performance that drivers have come to expect.
