Land Rover LR3 Spark Plugs - NGK - Laser Iridium (IFR5N10), Box of 4 - `05-`09. Precision OE-equivalent iridium spark plugs designed to meet factory specifications for the LR3 (2005–2009) and similar Jaguar/Land Rover applications.

These NGK Laser Iridium plugs combine long life with consistent ignition performance. The iridium-tipped center electrode is exceptionally hard (about six times harder than platinum), providing extended service life while maintaining a stable spark gap. High-grade pure alumina ceramic insulators and a 98% pure copper core help control heat transfer and support reliable starts and steady combustion. Many Laser Iridium designs also include a platinum pad on the ground electrode to promote even wear in distributorless ignition systems.
