The NGK 6046 Iridium Spark Plugs, also known by part number DCPR7EIX, are engineered for enhanced performance and extended service life. The specific dimensions include a 12mm-19mm thread size, a 0.8 mm plug gap, and a 16mm hex size, ensuring precise fitment and reliable contact. NGK is a leading global supplier of original equipment spark plugs, making these Iridium IX plugs a top choice for many vehicle manufacturers. They are known for providing a superior combination of performance and longevity compared to conventional spark plugs. This listing is for a set of four spark plugs, suitable for specific Harley-Davidson models including Twin Cam and XL engines. While widely listed for Twin Cam models, some sources indicate potential fitment discrepancies, advising users to verify compatibility. It's important to check your specific vehicle application and owner's manual to ensure proper fit and optimal performance. The spark plugs are typically pre-gapped, but adjustment may be necessary for some applications.
