YEHERIT UF262 Round Ignition Coil Kit for GM V8 8-Piece — 8mm Spark Wires & Platinum Plugs for 4.8L/5.3L/6.0L

YEHERIT 8-piece UF262 round ignition coil kit includes eight round UF262 coils, eight 8mm 9748 spark plug wires and eight 41-962 platinum spark plugs for V8 GM engines.

This complete ignition set replaces worn coils, wires and plugs on compatible GM 4.8L, 5.3L and 6.0L V8 engines. The kit is designed as a direct-fit aftermarket solution for many Chevy, GMC and Cadillac models listed in the fitment, and uses the round UF262 coil shape—confirm your vehicle uses round coils, not square UF271 units, before ordering. Components are built with heat-resistant materials and nichrome-core wire for improved durability and conductivity.

How do these UF262 round coils improve ignition reliability?

The UF262 round coils are engineered to restore consistent spark delivery across all eight cylinders, reducing misfires and unstable idle that result from degraded coils. Replacing a full bank ensures balanced performance and smoother engine operation.

• Eight matched round ignition coils (UF262) replace worn or failed units.
• Design reduces intermittent misfires and rough idling when installed correctly.
• Direct-fit form factor for compatible GM V8 engines—no custom wiring required.

What do the 9748 8mm spark plug wires and nichrome core offer?

The included 8mm spark plug wires come with a nichrome core for enhanced heat resistance and corrosion protection, helping maintain signal strength under high-temperature conditions. These wires are designed to minimize electrical interference and provide reliable connection between coils and spark plugs.

• Nichrome-core construction improves thermal tolerance and longevity.
• 8mm diameter optimizes balance between flexibility and insulation.
• Pre-terminated ends for simple plug-and-play replacement.

Are the 41-962 platinum spark plugs included a good match?

The kit includes eight 41-962 platinum spark plugs chosen for consistent spark performance and extended service life compared with standard copper plugs. Platinum tips typically resist wear longer, supporting steady combustion and more predictable maintenance intervals.

• Platinum electrode for extended durability and stable spark gap life.
• Matched to the coil and wire set to optimize ignition timing and consistency.
• Packaged eight per kit to replace an entire cylinder bank at once.

Which vehicles and part numbers does this kit fit?

This set is compatible with a wide range of GM trucks and SUVs with 4.8L, 5.3L and 6.0L V8 engines—common examples include Silverado, Suburban, Tahoe, Sierra, Yukon, Escalade and H2. Confirm part shape: this offering is ROUND (UF262) not SQUARE (UF271). Review your vehicle’s coil shape and the provided part numbers before purchase.

• Common fitment: Chevy Avalanche, Tahoe, Trailblazer, Express, Silverado, Suburban, SSR.
• GMC: Envoy, Yukon, Savana, Sierra; Cadillac: Escalade EXT/ESV; Hummer H2 listed.
• Included part numbers: UF262 coils, 41-962 plugs, 9748 wires (see product pack list).

Who this is for: This kit is intended for owners and technicians servicing GM V8 trucks and SUVs that use round UF262 ignition coils who want a single-purchase replacement for coils, wires and plugs. It’s suitable for DIY mechanics comfortable confirming coil shape and completing routine ignition work, as well as professional shops seeking a matched ignition set to address misfires, rough idle or timing inconsistencies. Note: verify your vehicle uses round-style coils (UF262) before ordering—this kit is not compatible with square UF271 coils. YEHERIT provides one-year product quality support for buyer confidence.
