Spark plugs

1 The spark plugs are located on the sides of the engine. Note: The 2.3L (1993 through 1997) and 2.5L (1998 through 2001) four-cylinder engine models are equipped with two spark plugs per cylinder, for a total of eight spark plugs. The spark plugs on the intake manifold side of the engine are very difficult to access, requiring removal of intake system components and/or several special tools (long extensions, swivel socket, etc). The maximum replacement interval for spark plugs specified by the manufacturer is as follows:
  1. 1993 2.3L engine - 30,000 miles
  2. 1993 3.0L and 4.0L engines - 60,000 miles
  3. 1994 2.3L and 4.0L engines - 60,000 miles
  4. 1994 3.0L engine - 100,000 miles*
  5. 1995 through 2000 four-cylinder engines - 60,000 miles
  6. 1995 through 2010 3.0L and 4.0L engines - 100,000 miles*
  7. 2001 through 2010 four-cylinder engines - 100,000 miles
  8. 2011 models - 105,000 miles
* While the manufacturer specifies a 100,000-mile interval for most late-model engines we recommend a 60,000-mile interval for these engines, since fouling and erosion can often cause misfiring before 100,000 miles
