MAS One Round Ignition Coils on Plug Pack for Chevy GMC V8 4.8L 5.3L 6.0L UF262 — OE-Style Fitment, Heat-Resistant

These coils are made as OE-style replacements that match the electrical and mechanical fitment of many GM V8 models produced across the late 1990s through the mid-2000s. They replace factory part numbers such as UF262, 10457730 and related interchange references, and are offered with a one-year limited warranty. Because GM switched coil styles mid-year on some models, it's important to confirm your vehicle uses the round UF262 design before ordering.

How do I confirm this coil fits my vehicle?

Fitment varies by model year and engine displacement. Check the original coils on your engine for the round UF262 shape and compare the part numbers stamped on the coil. Use the detailed vehicle list provided to cross-reference your year, make, model, and engine size before purchase.

• Look for UF262, 10457730, C1251, or similar part markings on your current coil.
• Verify engine size: 4.8L, 5.3L, or 6.0L V8 as listed in the fitment table.
• If coils are square instead of round, you likely need UF271 (do not buy UF262).

What performance and durability features should I expect?

MAS coils are built to match OE electrical characteristics and physical dimensions so they install without modification and maintain consistent spark delivery. Materials and connectors are selected to resist heat cycling and vibration typical of V8 truck and SUV engines. While not a performance upgrade, they are intended to restore proper ignition operation when replacing failed factory coils.

• OE-style electrical compatibility for plug-and-play replacement.
• Heat-resistant construction for under-hood durability.
• Factory-style connector and mounting points for straightforward installation.

Which vehicle models are supported by this MAS coil pack?

This round-design UF262 replacement fits a wide range of GM trucks, SUVs, and vans built from the late 1990s through about 2007. The fitment list covers many Chevrolet and GMC Silverado/Sierra, Tahoe/Suburban/Yukon, Express/Savana, Avalanche, Silverado HD, and Cadillac Escalade models with 4.8L, 5.3L, and 6.0L V8 engines.

What warranty and part interchange information is included?

MAS backs these coils with a one-year limited warranty covering manufacturing defects and premature failure under normal use. The product lists common interchange numbers to help match your original coils and avoid ordering the wrong style. Keep your original part number handy to streamline returns or warranty claims.

• One-year limited warranty with replacement support.
• Interchange references: UF262, 10457730, 12563293, C1251, D-585, and others.
• Verify compatibility first to prevent mis-orders (square vs. round coil distinction).
