ENA Ignition Coil and Control Module Kit for GM 4.3L/5.7L Trucks SUVs (Direct-Fit, OE-Style)

ENA’s ignition coil and control module set replaces worn factory units to restore spark delivery and reliable starting on compatible Chevrolet and GMC V6/V8 models.

If your classic GM truck, van or SUV from the late ’90s to early ’00s is showing rough idle, misfires or hard starts, a failing coil pack or ignition module is a common cause. This ENA kit includes one multi-terminal coil pack and a matching ignition control module manufactured as direct-fit replacements for many Chevrolet and GMC applications. Built to meet OE-style fitment and electrical specifications, it gives technicians and DIYers a straightforward swap without extensive adaptation.

What vehicles and engines will this ENA coil & module work with?

This kit is engineered to fit a broad range of GM models equipped with the 4.3L V6 and several V8 engines (5.0L, 5.7L, 7.4L) across model years roughly 1996–2007. Fitment spans Chevrolet and GMC full-size trucks, SUVs, and vans including Astro, Blazer, S10, Silverado, Tahoe, Express/Savana, Sierra, Sonoma, Jimmy and others as listed.

• V6 4.3L installs: Blazer, Astro, S10, Silverado, Express, Jimmy, Safari, Savana, Sonoma (1996–2007 ranges).
• V8 support: 5.0L, 5.7L, 7.4L on C/K, Tahoe, Express/Savana vans and related GM platforms (1996–2002 mostly).
• Check vehicle year, engine displacement, and OEM reference numbers for exact match before ordering.

How does this ENA replacement match original equipment?

ENA designs the coil pack and ignition control module to replicate OE mounting points, terminal counts and 12V electrical characteristics so the parts bolt into the factory locations and plug into existing harnesses. The kit’s materials and internal interconnects follow industry standards to provide compatible conductivity and sealing for under-hood use.

• Direct-fit bolt-on mounting for both coil pack and module to avoid drilling or adapters.
• Coil pack: three-terminal configuration; module: four-terminal attachment points.
• 12-month limited warranty and part references to OEM numbers for cross-checking compatibility.

What are the installation and performance considerations?

Installation is straightforward for mechanically inclined owners or professional installers: disconnect battery, unbolt and remove the old module and coil pack, swap in the ENA units and reconnect wiring. Replacing both the coil pack and module together helps eliminate dual-failure scenarios and can resolve intermittent misfires or poor idle caused by degraded ignition components.

• Recommended: confirm fit using vehicle specifics (year, make, model, engine) before purchasing.
• Tools needed: basic hand tools, torque wrench for correct bolt torque, dielectric grease for terminals if desired.
• Includes one coil pack and one control module; replace both for best results when symptoms involve ignition timing or multiple misfires.

Who is this kit best for? This ENA ignition coil and module set is ideal for owners, mechanics and restoration shops working on late-1990s to early-2000s Chevrolet and GMC trucks, SUVs and vans that use 4.3L V6 or the listed V8 engines. It suits drivers who need a cost-effective direct replacement that installs with OE-style fit, fleet maintenance technicians who prefer standardized parts, and DIY enthusiasts looking to remedy misfires, hard starts or check-engine light codes tied to ignition faults. Always verify the OEM reference numbers and your vehicle’s engine code or VIN fitment before ordering to ensure compatibility.
