DENSO Auto Parts Spark Plug P/N:3370
DENSO Auto Parts 3007 spark plug for the 1990-1991 Volkswagen Jetta 4-cylinder 2.0L and other vehicles ignites the air-fuel mixture in each cylinder.
Hard starting, a rough idle, a misfire or poorer fuel economy can mean worn plugs. Weak ignition coils or wires, a dirty fuel injector or a vacuum leak can also be behind those signs, so find the cause before buying plugs.
This OE-grade plug is a direct-fit replacement for the 1990-1991 Volkswagen Jetta 4-cylinder 2.0L, a spark plug for the 1987-1990 Jeep Cherokee 6-cylinder 4.0L and for the 1990-1991 Volkswagen Passat 4-cylinder 2.0L, and it fits many other vehicles. The two Volkswagens take four plugs each and the Jeep takes six. If your car is not named here, look up your year and engine in the "Vehicles it fits" section.
