These NGK Iridium IX spark plugs feature an ultra-fine center electrode designed to balance durability with a precise, consistent spark. The fine-wire iridium tip helps reduce the voltage required for a spark while maintaining the strength and longevity expected from a premium performance spark plug.
Iridium is significantly harder than the metals commonly used in traditional spark plugs, allowing NGK to produce a plug that supports reliable spark performance, strong service life, and improved consistency. This makes the LTR7IX a strong option for performance-minded applications where spark quality and durability matter.
Whipple highly recommends this spark plug for Ford F-150, F-250, and SVT Raptor 6.2L based engines running a supercharger at standard boost levels.
