Complete V8 Ignition Tune-Up Kit: Coils, Iridium Plugs & Wires

Don't let a rough idle, cylinder misfire, or hesitation hold back your rig's performance. Whether you are hauling heavy loads in a Sierra 2500HD, hitting the trails in a Tahoe, or restoring factory throttle response to your Silverado 1500, this complete 24-piece ignition kit is the ultimate fix.

Engineered as a direct replacement for UF414 and 94567 setups, this all-in-one package delivers a hotter spark, improved fuel economy, and reliable combustion for GM's 4.8L, 5.3L, 6.0L, and 6.2L engines.

Key Benefits

• The Complete Fix: Includes 8 heavy-duty ignition coils, 8 high-performance iridium spark plugs, and 8 premium silicone plug wires to entirely overhaul your ignition system at once.

• Iridium Power: Upgraded iridium spark plug tips provide superior durability and a more concentrated spark compared to standard factory copper or platinum plugs.

• Built to Last: High-dielectric plastic coil housings and premium wire jacketing resist extreme engine bay heat, moisture, and heavy vibration.
