ENA Spark Plug Wire Set for Chevy GMC Cadillac V8 5.0L/5.7L (1996–2003) — Direct-fit, Improved Insulation

ENA Spark Plug Wire Set is a direct-fit replacement kit for Chevy, GMC and Cadillac V8 engines (5.0L / 5.7L) from 1996–2003, engineered to restore reliable ignition performance.

If your V8 is misfiring, running rough, or showing low spark voltage after years on the road, worn spark plug wires are a common culprit. This ENA wire set is manufactured to match or improve on original equipment specifications, providing an easy, out-of-the-box swap for models including Chevy/GMC C/K series trucks, Express and Savana vans, and Cadillac applications that use the specified 5.0L and 5.7L V8 engines. The kit replaces OE numbers such as 9718Q, 88862381 and aftermarket references like 35-8150.

How does this wire set improve ignition reliability?

The ENA set delivers consistent electrical conductivity and insulation to reduce misfires, radio interference, and premature wear from heat and vibration. Components are either identical to or upgraded from OE parts so that the spark reaches the plugs efficiently under normal driving conditions.

• High-quality conductor materials for steady spark transfer
• Improved dielectric insulation to resist heat and leakage
• Factory-style boots and terminal fittings for secure connections
• Pre-cut lengths and correct routing for plug-and-play install

Will this fit my 1998–2002 Chevy or GMC truck?

The set is designed specifically for many Chevrolet, GMC and Cadillac V8 applications from 1996 through 2003 that use 5.0L or 5.7L engines. Vehicle fitment depends on engine and model configuration, so always confirm compatibility before purchase.

• Direct replacement for C1500, C2500, C3500 and K-series variants listed
• Works with Express and Savana van models cited in product title
• Cross-references OE numbers (e.g., 9718Q, 88862381) for verification
