NGK Spark Plug P/N:B7HS
NGK UR55 spark plug for the 1984-1986 Chevrolet Camaro 4-cylinder 2.5L and other vehicles ignites the air-fuel mixture in the cylinder. As one of the NGK spark plugs in the V-Power line, it is recommended for vehicles with OE nickel alloy plugs, not for vehicles with factory precious metal plugs.
Worn plugs can bring hard starts, a rough idle or misfires. These signs alone do not prove the plugs are at fault; a vacuum leak, for one, produces a rough idle too.
Along with the 1984-1986 Chevrolet Camaro 4-cylinder 2.5L, this plug fits the 1985-1993 Chevrolet S10 4-cylinder 2.5L and the 1987-1993 Chevrolet LLV 4-cylinder 2.5L, and all three take four plugs. Owners of other cars can look up their year and engine in the "Vehicles it fits" section.
