Bosch Spark Plug P/N:9612
Bosch 8157 spark plug for the 1993-1998 Nissan Altima 4-cylinder 2.4L and other vehicles ignites the air-fuel mixture in each cylinder. Its double platinum, OE Fine Wire design meets Original Equipment specifications for double platinum spark plugs.
A weak ignition coil, a worn plug wire or a fuel delivery problem can also be behind a misfire, rough idle or hard start, so find the cause before you replace the plugs. Worn spark plugs can also show up as lower fuel economy.
This plug is a spark plug for the 1990-1991 Toyota Corolla 4-cylinder 1.6L and for the 1991-1994 Nissan Sentra 4-cylinder 2.0L, the 1995-1999 Sentra 4-cylinder 1.6L and the 1998-2001 Sentra 4-cylinder 2.0L.
