NGK Iridium IX Spark Plugs

NGK Iridium IX spark plugs feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plugs—and just thin enough to create an accurate and consistent spark. They represent the ultimate evolution of spark plug technology and performance. Iridium is the hardest metal used in spark plugs today—six times harder than platinum. This allowed NGK engineers to reduce the voltage requirement for a spark. Iridium IX plugs are available in more than a hundred configurations for universal and vehicle-specific applications.

Twin Air Fuel Filters

You'd be amazed at the dirt and debris that can work its way into your gas can--and from there, into your fuel tank. Twin Air fuel filters with monofilament screen pockets insert in your tank to catch particles as small as 40 microns (.00165 in.) while allowing the gas to flow freely. Available for many off-road bikes and ATVs, each flange is custom-sized for each modern 4-stroke model to ensure a leak-proof seal. To clean, simply remove the filter, turn it inside-out, and clean out the debris that COULD have been in your engine. Choose the Twin Air fuel filter designed for your powersports ride.
