Infiniti Q45 Replacement Spark Plugs Information


The spark plug is the final component of the car's ignition electrical system where the current generated is finally emitted as a spark inside the cylinder to ignite the mixture of air and fuel. Performance of Infiniti Q45 spark plugs deteriorates over a period of time due to exposure to combustion. The heat affects the spark plug and the tip often gets covered with soot and carbon deposits. The end result is that the spark is not generated properly and this affects ignition. Cleaning the spark plug is a good way of keeping the engine in good condition. Excessive deposit of carbon may also indicate a problem in some other component of the vehicle. Improper air mass meter boot functioning may cause the on board computer to mess up the air fuel mix. This will create an over rich mixture generating more pollutant and affecting performance of Infiniti Q45 spark plugs. Over the years, car makers have come up with newer technologies to improve spark plug performance. Most OEM plugs come with a platinum coating to reduce deposit of pollutants on the spark plug and enhance life.


They are available for the following Infiniti Q45 years: 2006, 2005, 2004, 2003, 2002, 2001, 2000, 1999, 1998, 1997, 1996, 1995, 1994, 1993, 1992, 1991, 1990, 06, 05, 04, 03, 02, 01, 00, 99, 98, 97, 96, 95, 94, 93, 92, 91, 90. This part is also sometimes called Infiniti Q45 Spark Plug.
