Spark plug wire set for the 1996 to 1998 Chevrolet and GMC C/K (GMT400) with the 5.0 or 5.7 Vortec V8.

Part numbers

Packard Wire Co, blue, 8mm spiral core. No confirmed GM OEM number.

Fits

1996 to 1998 Vortec 5.0/5.7 V8 only. The 1988 to 1993 TBI trucks need a different set, see the TBI spark plug wire listing instead. Physically the same wires also cover the 1996-2000 Suburban, Tahoe and Yukon, but this listing is scoped to the GMT400 truck years OBScure sells for.

Why it matters

Wire insulation degrades with age and under-hood heat, leading to misfires and rough running that can be hard to pin down. High running temperatures here mean this wears faster than it would in a milder climate.

What you get

One new set of plug wires, blue, 8mm spiral core, 270 ohms per foot. Brand Packard Wire Co, made in the USA.
