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 improved fuel efficiency. The platinum firing tip prevents gap erosion, extending the service life, while the high alumina ceramic insulator enhances thermal conductivity and insulation for added strength. Designed with a multi-rib insulator to prevent flash-over and a nickel-plated shell for superior corrosion resistance, these spark plugs deliver reliable, long-lasting performance. The extra-long projection of the standard center electrode design, combined with a nickel ground electrode tip, optimizes ignition for better acceleration and reliability. With a tapered seat type and integrated resistor, these performance-grade spark plugs are engineered to meet the demands of your engine while providing excellent value and durability.

Product Features:

E3’s Diamond Fire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn
Smoother Acceleration & Idle – The faster flame initiated by the spark plug results in a more complete burn of the ingested fuel charge. More pressure is created against the piston more fuel is put to work
Energy – Power output improved up to 6% on average in the typical operating ranges. Results will vary.
Efficiency – The “diamond shaped” side wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and larger flame kernel. The result is that more fuel is put to work durin
E3’s patented Diamond Fire Technology provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
The Spark Plugs are pre-gapped at the factory and cannot be adjusted.
