NGK NGK Iridium IX Spark Plug P/N:3903
NGK 2115 spark plug for the 1990-1998 Hyundai Sonata V6 3.0L, the 1999-2005 Sonata 4-cylinder 2.4L and other vehicles ignites the fuel mixture in the cylinder. It is one of the NGK spark plugs in the Iridium IX line.
A worn plug can show up as hard starting, a rough idle, a misfire or poorer fuel economy, but a coil, the wiring or the fuel supply can produce those symptoms too. With the engine off and cool, look at the plug's electrode and insulator for rounding, oil or deposits to find the cause before replacing it.
The 1986-1989 Honda Accord 4-cylinder 2.0L and the 2001-2006 Kia Optima 4-cylinder 2.4L take it as well, along with many other cars and motorcycles. Both of those take four plugs, while the 1990-1998 Hyundai Sonata V6 3.0L takes six. Open the Buyer's Guide tab to check your exact model and engine.
