NGK NGK Iridium IX Spark Plug P/N:4085
NGK 7544 spark plug for the 2005-2010 Polaris Phoenix 200 196cc and other vehicles ignites the air-fuel mixture in each cylinder. Among NGK spark plugs, this one is meant for modified or high performance applications and as an upgrade to OE nickel alloy plugs.
Hard starting, a rough idle or a misfire can mean the plug is worn, though a weak ignition coil or a worn plug cap can be behind the same signs. The engine takes one plug per cylinder.
The vehicles it fits include the 2005-2010 Polaris Phoenix 200 196cc, the 2018-2025 Polaris Ranger 150 Efi 150cc and the 2021-2025 Polaris Outlaw 70 Efi 70cc. If your machine is not named here, look it up in the "Vehicles it fits" section.
