• 【PERFORMANCE UPGRADE】 Replace worn plugs and wires with this complete 8-set ignition kit. The 41-110 iridium spark plugs deliver superior ignitability, longer service life (up to 100k miles), and consistent combustion, while the M8-48322 8mm spark plug wires feature low-resistance carbon core and high-dielectric silicone for reliable spark transmission – reduces misfires, rough idle, and hard starts.
• 【OEM EXACT FIT & DURABILITY】 Engineered to meet or exceed original equipment specifications. The 41-110 iridium spark plugs (replace 12680072, 12621258, 41-985, 12571164) feature a tapered cut ground electrode and iridium center electrode for extreme durability. The M8-48322 wire set (replace 48322, 7831, 483227831 ) uses double-layer high-temp silicone jacket plus fiberglass braiding to resist heat up to 500°F, oil, and abrasion – ensures stable electrical connection even under severe conditions.
• 【WIDE COMPATIBILITY – LS TRUCK & SUV】 For Chevy Silverado 1500/2500HD/3500HD (2007-2014), Suburban/Avalanche/Tahoe (2007-2014), Express (2007-2011), Caprice/Colorado/Corvette;For GMC Sierra/Yukon/Savana (2007-2014), Canyon/Envoy;For Cadillac Escalade, ESV, EXT (2007-2014); Pontiac G8 (2009).
