The Texas Speed 10mm LS Truck & LSA Spark Plug Wires with Max-Plus Heat Protection are a heavy-duty wire set made for the coil layout on LS truck engines and the supercharged LSA. Texas Speed lists them for LS-based truck engines such as the 4.8L, 5.3L and 6.0L and for LSA engines in both factory and swapped applications, in red or black.
The oversized 10mm wire is intended for enhanced current delivery and the Max-Plus insulation is Texas Speed's upgraded thermal protection for tight, hot engine bays and forced induction setups. The wires use high-temperature silicone jackets over a premium core and are tailored to coil-on-plug LS truck and LSA ignition. Texas Speed describes them as a fit for turbocharged, supercharged or high-compression engines as well as stock replacements. Select the color at ordering.

FAQ
What engines do the Texas Speed 10mm LS truck and LSA plug wires fit?
Texas Speed lists them for LS-based truck engines such as the 4.8L, 5.3L and 6.0L found in Silverado, Sierra, Tahoe, Suburban, Yukon and Escalade, and for LSA supercharged engines in factory or swapped applications.
Why are there separate truck and car LS plug wire sets?
LS truck engines and the LSA position the coils differently from LS car engines, so the wire lengths differ. This set is cut for the truck and LSA coil layout; Texas Speed sells a separate LS car set.
What is Max-Plus heat protection on these wires?
Max-Plus is Texas Speed's upgraded thermal insulation for the 10mm wires, built to resist the extreme temperatures found in tight engine bays, near headers and on forced induction engines.
Are these wires good for supercharged or turbocharged trucks?
Yes. Texas Speed describes the 10mm Max-Plus truck and LSA wires as ideal for turbocharged, supercharged or high-compression engines, with the larger wire chosen for current delivery and misfire resistance under heat.
What colors are the LS truck and LSA wires available in?
The Texas Speed 10mm Max-Plus LS truck and LSA wires are offered in red or black, selected at ordering. Both colors use the same wire construction.
