Cable Master 10.2mm Racing Spark Plug Wires for GM LS V8 1999–2007 — Red, Kevlar-Core & Silicone Jacket

High-performance 10.2 mm spark plug wire set by Cable Master engineered for GM LS-family V8 engines (4.8L, 5.3L, 6.0L, 8.1L) from 1999–2007, offering durable silicone jacketing, kevlar cores and superior RFI suppression in a race-ready red finish.

This complete set of spark plug leads is built to replace worn OE wiring on many Chevrolet and GMC trucks, SUVs and specialty chassis—Escalade, Avalanche, Silverado, Tahoe, Sierra, Suburban, Yukon, H2 and select tiltmaster/W4500 applications. Designed for LS-based Gen III/IV small-block V8 motors including LR4, LM7, L59, L33, LQ4 and LQ9 families, the Cable Master wires provide a long-lived, low-resistance path for reliable ignition under high heat and demanding driving conditions.

Which vehicles and engines will these wires fit?

These wires are compatible with a broad range of GM full-size trucks and SUVs from model years 1999 through 2007. They cover factory engine displacements listed for small block Gen III/IV V8s and match common OEM part numbers for straightforward replacement.

• Compatible models: Escalade, Avalanche, Silverado (1500/2500/3500 variants), Tahoe, Sierra, Suburban, Yukon, H2, W4500 Tiltmaster
• Engine sizes: 4.8L (294), 5.3L (325), 6.0L (364), 8.1L (496)
• Engine families: LR4, LM7, L59, L33, LQ4, LQ9 (GM LS V8 platforms)
• OEM cross-reference numbers included for verification

How are these wires constructed to handle heat and performance demands?

The Cable Master set uses a layered build to resist abrasion, high underhood temperatures and electrical interference. A kevlar-reinforced core and nickel wire-wound conductor deliver durability and efficient voltage transfer while a double silicone jacket and fiberglass layer protect against tears and heat soak.

• Kevlar core for long life and tensile strength
• Nickel-wound conductor provides low resistance and consistent spark energy
• Double silicone jacket plus fiberglass layer for heat and abrasion resistance
• High-temperature boots and insulation to maintain reliable seals

Will these wires affect electronic systems and ignition reliability?

Cable Master wires include design elements to reduce radio-frequency interference (RFI), helping protect sensitive engine electronics and preventing ignition noise on modern vehicles. Low-resistance conductor construction helps sustain stable spark delivery across cylinders for consistent firing performance.

• Engineered RFI suppression to minimize electronic interference
• Low electrical resistance preserves voltage delivery to spark plugs
• Premium silicone boots ensure secure spark plug connections and moisture resistance
• Color-coded/red finish simplifies routing and adds a custom look

Who is this for: Drivers and technicians replacing aged or damaged ignition leads on late‑model GM LS-based V8 trucks and SUVs who want a durable, performance-oriented upgrade. These wires suit DIY mechanics and professional shops that require OE-fit compatibility across many Chevrolet and GMC models from 1999–2007, plus anyone wanting improved heat resistance and reduced electrical noise without changing ignition components or tune.
