NGK Spark Plug P/N:BKR5E-11
NGK PLFR5A-11 spark plug for the 2002-2006 Nissan Altima 4-cylinder 2.5L or V6 3.5L and other vehicles ignites the fuel mixture in the combustion chamber. It is one of the NGK spark plugs built with double platinum metallurgy.
A worn plug can show up as hard starting, an unsteady idle or lower fuel economy. A weak ignition coil, a fuel injector problem or a vacuum leak can be behind those same signs, so find the cause before buying plugs.
This platinum spark plug suits the 2002-2006 Nissan Altima, which takes four with the 4-cylinder 2.5L and six with the V6 3.5L. It is also a spark plug for the 2000-2006 Nissan Sentra 4-cylinder 1.8L and the 2002-2006 Sentra 4-cylinder 2.5L, and it fits as spark plugs for the 2001-2004 Nissan Pathfinder V6 3.5L and the 2005-2006 Pathfinder V6 4.0L, along with many other vehicles. If your car is not named here, open the "Vehicles it fits" section to check your exact model and engine.
