The NGK Spark Plugs Iridium IX BPR6EIX-11 spark plug is designed to deliver reliable ignition, efficient combustion, and extended service life for compatible automotive and powersports applications. Built with a fine iridium center electrode, this spark plug supports consistent spark performance while reducing the voltage required from the ignition system. Its tapered electrode design also helps promote dependable starts and smooth engine operation.
The iridium electrode is approximately 25% smaller than a platinum electrode and about one-quarter the size of a conventional nickel electrode. This ultra-fine design concentrates the spark for reliable ignition and can help reduce strain on ignition components. A new metal shell plating provides enhanced resistance to corrosion, helping the plug withstand demanding under-hood conditions.
Use the NGK Spark Plugs Iridium IX BPR6EIX-11 only where the vehicle or equipment manufacturer specifies this heat range, reach, and plug configuration. The manufacturer part number is 3903, and the vendor part number is BPR6EIX11. Verify application details, thread specifications, and required gap against the manufacturer’s fitment information before installation. This product is supplied as an individual replacement spark plug.
