Description: Specifically engineered to help Polaris vehicles perform at their best This iridium spark plug is the latest evolution in high performance plugs The natural properties of iridium help enable the plugs to burn fuel more efficiently and to deliver better performance iridium plugs have a minimum service life of 100,000 miles (service life varies with individual driving conditions) Since iridium is one of the densest materials found on earth, the iridium-tipped center electrode is half the size of a platinum electrode, and 1/5 the size of a conventional nickel electrode The specially designed electrodes increase the electric field strength at the gap, reducing the voltage required for sparking to begin Specifications:- 14mm Thread Size- 25.4mm (1") Reach- 5/8" (16mm) Hex Size- Tapered Seat- Copper Core- 0.6mm Finewire Center Electrode Design- Platinum Sidewire Technology- Solid Terminal Nut- .051" (1.3mm) Gap- Heat Range 3- 1 Spark Plug Designed To Fit: 2019 Slingshot GT 2018-2019 Slingshot S 2018 Slingshot SLR LE 2018 Slingshot GT LE 2017-2019 Slingshot SLR 2017 Slingshot SL LE 2015-2019 Slingshot SL 2015-2017 Slingshot WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov.
