MCCKLE Iridium Spark Plugs & 8mm Plug Wires Set for GM V8 (8 Plugs + 8 Wires) — 41-110 & M8-48322

MCCKLE 41-110 iridium spark plugs with M8-48322 8mm spark plug wires is a 16-piece ignition replacement set designed to restore spark performance on compatible GM V8 engines.

If your vehicle is showing age-related ignition symptoms — rough idle, reduced throttle response, or harder cold starts — renewing both spark plugs and plug wires at the same time is a practical way to return consistent firing and smoother running. This package pairs eight iridium-tip spark plugs (replacement for 41-110 and related part numbers) with eight high-quality 8mm spark plug wires (replacement for M8-48322 and listed equivalents). The set was built to match the fit and firing requirements of a wide range of late-2000s and early-2010s Chevy, GMC, Cadillac, Pontiac models that originally used these part numbers.

Which vehicles will these MCCKLE parts fit?

These spark plugs and wires are specified as direct-replacement items for many GM full-size trucks, SUVs and some performance cars from roughly 2007–2014. Always confirm compatibility by cross-checking your engine’s part numbers or owner's manual before purchase.

• Chevrolet models: Avalanche, Tahoe, Caprice, Colorado, Corvette, Express vans, Silverado 1500/2500HD/3500HD, Suburban (specific years listed).
• GMC models: Savana, Sierra 1500/2500HD/3500HD, Canyon, Yukon, Yukon XL (specific years listed).
• Other compatible: Cadillac Escalade ESV/EXT, Pontiac G8 where applications match the listed part numbers.

How do the iridium plugs and 8mm wires improve ignition reliability?

Iridium spark plugs offer a fine center electrode for a stable spark at high voltage and extended service life compared with standard copper plugs. Paired with properly insulated 8mm wires, the complete ignition path reduces misfires and electrical leakage that can cause rough running.

• Iridium tip for concentrated spark and long wear life.
• 8mm wires provide robust insulation and low-resistance conduction.
• Matched set ensures correct firing order and plug-to-wire length for compatible engines.

What’s included and how does installation go?

The kit ships with eight 41-110-style iridium spark plugs and eight M8-48322 spark plug wires. Installation is straightforward for anyone familiar with basic engine maintenance: replace plugs one cylinder at a time, route and seat wires according to firing order, and torque plugs to the OEM specification.

• Contents: 8 spark plugs (41-110 series) + 8 plug wires (M8-48322 series).
• Do one cylinder at a time to avoid mix-ups; follow factory torque specs.
• Inspect boots and connectors; use dielectric grease if recommended by vehicle guidelines.

Are these MCCKLE parts OEM or aftermarket, and any brand notes?

These items are aftermarket replacements designed to match the referenced OEM part numbers (41-110, M8-48322 and equivalents). They are manufactured and sold by MCCKLE, not by General Motors or any OEM brand. Customers should verify fitment for their exact engine variant before installing.

• Aftermarket replacement built to fit listed GM part numbers.
• Not produced or sold by GM; MCCKLE is the supplier brand.
• Verify application with engine model and VIN when in doubt.

Who this is for: This replacement set is intended for owners and DIY mechanics of compatible Chevy, GMC, Cadillac, or Pontiac vehicles who want a complete ignition refresh — replacing both plugs and wires at once to restore consistent spark delivery. It's also suited to technicians servicing fleets or performing scheduled maintenance where cost-effective, matched ignition components are required. If you need a full 8-cylinder ignition overhaul with parts matched to the 41-110 and M8-48322 family of numbers, this MCCKLE kit provides the core components to get the job done.
