ENA Ignition Coil Kit 8‑Piece with Iridium Plugs & Red Silicone Wires — UF414 Round Fit

ENA's 8-piece ignition kit delivers eight round UF414-compatible coils, eight iridium platinum spark plugs, and eight red silicone spark plug wires engineered to replace factory units on many GM V8 engines.

This complete ignition set from ENA is built for direct-fit service on a long list of Chevrolet, GMC, Cadillac and related GM vehicles fitted with round UF414 coil packs. The kit pairs bolt-on, 12V coil packs with high‑performance iridium platinum spark plugs and heavy-duty red silicone wires, giving you a single-purchase solution when replacing all eight ignition circuits at once. Before ordering, verify your original coils are the round UF414 style (not the square UF413) to ensure proper fitment.

Which vehicles will these ENA coils, plugs, and wires fit?

The kit covers many GM V8 models across Chevrolet, GMC, Cadillac and Pontiac from mid-2000s through mid-2010s. Fitment includes Silverado, Tahoe, Suburban, Avalanche, Camaro, Colorado, Sierra, Yukon, Escalade, and more — check your year and engine size against the detailed list.

• Common Chevy fits: Silverado 1500 (2007–2013 4.8L/5.3L/6.2L), Tahoe (2007–2014 5.3L), Suburban (2007–2013 6.0L).

• Always confirm with your VIN or the Amazon Confirmed Fit tool; this kit replaces UF414-style coils only.

How do these parts compare to the original equipment?

ENA designed the coils and wires for plug-and-play installation with the same terminal count and bolt-on mounting as many factory units. The iridium platinum spark plugs use a long-life tip material and a 1.0 in gap specification to match OEM performance characteristics while offering improved durability.

• Coil specs: 12V, bolt-on mount, 4 terminals per coil, engine-bay mounting.
• Spark plugs: iridium platinum center, 1.0 in gap, 14 mm thread, 16 mm hex.
• Wires: 8 mm diameter, fiberglass-reinforced graphite core, silicone insulation in red for heat resistance.
• Reference cross-numbers included (UF414, 12573190, 1788407, etc.) to assist verification.

Can I install this kit myself, and what should I watch for?

Yes — the kit is intended for direct replacement and typically installs with basic hand tools. Work on a cool engine, label or replace one cylinder at a time to maintain firing order, and follow torque recommendations for plug seating to avoid damage.

• Confirm coil shape: this kit fits round UF414 coils only (not square UF413).
• Replace one spark plug/coil at a time to keep leads ordered correctly.
• Use correct torque on plugs (consult manufacturer specs) and inspect boots for proper seal.
• 12-month warranty included; have fitment info ready if contacting support.

Who this is for: Drivers and DIY mechanics who need a full eight‑cylinder ignition refresh for GM V8 trucks, SUVs and performance models and who prefer a matched set of coils, iridium plugs and color-matched silicone wires. It's suited to anyone replacing all eight ignition components at once for consistent performance and easier installation — as long as the vehicle uses round UF414-style coils. If you’re uncertain about coil shape or exact fit, verify with your vehicle’s service manual, VIN lookup, or the seller’s fitment tool before purchasing.
