- Critical Shape Check: SQUARE Coils (UF413) – This set contains 8 SQUARE ignition coils (UF413). Many GM vehicles use two different coil shapes (SQUARE UF413 vs. ROUND UF414). Please verify your current coil shape before ordering. If unsure, check the interchange part numbers below or contact us. We offer 1-year quality support for your peace of mind.
- Complete Kit with OE Cross-References – Includes 8 SQUARE ignition coils, 8 spark plugs (41-962 / 19299585), and 8 spark plug wires (9748UU / 748UU). Direct replacements for OEM numbers: UF413, D510C, D513A, 12570616, 12611424, C1511, 5C1554, 52-1819, IC533 (coils); 9748UU, 9748HH, 9748RR, 88862385, M8-48322R (wires). Everything you need for a full ignition tune-up.
- Broad Compatibility for GM Trucks & SUVs – Engineered for select GM vehicles with 4.8L, 5.3L, 6.0L, 6.2L V8 engines. Fits models like Chevy Silverado/Suburban/Tahoe/Express/Avalanche; GMC Sierra/Yukon/Savana; Cadillac Escalade/CTS; Buick LaCrosse/Rainier; Hummer H2/H3; Pontiac G8. Always use the Amazon fitment filter or match part numbers to confirm compatibility.
- Restore Power & Fuel Economy – Faulty ignition components cause rough idling, misfires, reduced gas mileage, and “check engine” lights. Our premium coils deliver a stronger, more consistent spark, restoring engine performance, improving throttle response, and maximizing fuel efficiency. Tested for high-RPM durability.
- Premium Build & Easy Installation – Coils feature a high-impact housing and neodymium magnet core for superior voltage output. Wires use a ferromagnetic Kevlar-reinforced fiberglass core with high-temp silicone insulation for excellent heat/oil/abrasion resistance. Pro tip: Apply dielectric grease to boots during installation to prevent cracking and ensure a secure seal.
