Cable Master 10.2mm Racing Spark Plug Wires for GM LS V8 2008–2020 — Blue, Kevlar Core & Low-Resistance

Cable Master 10.2 mm racing spark plug wires are a high-temperature, low-resistance ignition upgrade designed for GM LS-based 4.8–7.0L V8 engines from 2008–2020, delivered in a striking blue jacket for improved durability and electrical performance.

These spark plug wires combine a kevlar-reinforced core, nickel wire-wound conductor and a double silicone jacket to withstand heat, suppress radio frequency interference (RFI) and deliver consistent voltage to spark plugs. They fit many Chevy and GMC models—Escalade, Silverado, Tahoe, Camaro, Corvette, Sierra and more—covering common LS engine sizes. Built for both street and performance use, the set aims to replace worn OE leads or upgrade older ignition components without altering engine tuning.

Will these wires fit my 2008–2020 Chevy or GMC V8?

Yes — the set is engineered for GM small-block Gen III/IV (LS-based) V8 engines in the stated displacements. Compatibility covers factory 4.8L, 5.3L, 6.0L, 6.2L and 7.0L engines and a wide list of models from 2008 through 2020 (and some later model years listed by application).

• Fits models: Escalade, Avalanche, Camaro, Colorado, Corvette, Express, Impala, Silverado, Suburban, Tahoe, Sierra, Yukon, Savana, Canyon and related variants.
• Engine families: Chevy small-block Gen III/IV LS-series V8 engines (4.8–7.0L).
• Model years covered: primarily 2008–2020 with extended year references provided.

How do these wires improve ignition and engine response?

The wires use a nickel wire-wound (mag) conductor and kevlar core to reduce electrical loss while keeping resistance low, which supports a stronger, more reliable spark. That can translate to steadier idle, cleaner combustion under load and better throttle response compared with aged or high-resistance OE leads.

• Low-resistance, nickel-wound conductor for consistent voltage transfer.
• Kevlar core for mechanical durability and longer service life.
• Improved RFI suppression protects sensitive onboard electronics and radios.

What durability and heat protection features are included?

Multiple layers shield the conductor: a fiberglass layer beneath a heavy double silicone jacket resists tearing, while premium silicone boots tolerate high underhood temperatures. These construction details help prevent breakdown from heat, vibration and oil exposure common in engine bays.

• High-tear-strength double silicone outer jacket for abrasion resistance.
• Fiberglass wire layer and heat-resistant insulation for secure electrical isolation.
• Premium silicone boots designed for long-term high-temperature stability.

Are these plug wires easy to install and what part numbers do they replace?

Installation follows standard spark plug wire replacement steps—disconnect one wire at a time and match lengths to ensure proper routing. The set lists several OE reference numbers, making it straightforward to confirm fitment against existing components.

• Direct OE references included: 748UU, 19206447, 19209100, 19297035, 19351569/70 and others.
• Designed as a direct-replacement routing and boot fit for listed GM applications.
• Color-coded blue jackets help keep track of runs during installation.

Who is this for: Enthusiasts and technicians seeking a durable, performance-minded plug wire set for GM LS-based V8s from 2008–2020. Ideal for owners replacing aging ignition leads, upgrading to better RFI protection, or maintaining reliable spark delivery on trucks, SUVs and performance cars such as Silverado, Tahoe, Escalade, Camaro and Corvette. If you need dependable high-temp insulation, low electrical resistance and a factory-fit replacement, these Cable Master blue 10.2 mm wires are a practical choice.
