GPI Spark Plug Wire Set - Standard Length - Purple (1997+ GM LS Car Engines) - gpiLS-PUR-STD
Clean, Consistent Ignition for Naturally Aspirated LS Car Builds
The GPI Spark Plug Wire Set - gpiLS-PUR-STD is built for stock and naturally aspirated GM LS car engines that need dependable spark delivery and strong noise suppression without added extreme-heat materials. This Standard Version is ideal for street-driven and performance LS applications running factory-style exhaust and underhood temperatures.
Designed in a standard-length configuration, this set fits Chevy LS car engines with OEM-style coil placement. Each wire features a 30 ohms-per-foot high-inductance design, averaging ~400 mH per foot, helping reduce EMI/RFI interference while maintaining a clean, stable ignition signal for modern EFI systems.
A 200 TPI copper winding paired with a .085 - .090? conductor diameter delivers durability and consistent electrical performance. Finished in a bold purple sleeving with 45° LS coil boots and 45° spark plug boots, these wires provide proper routing, secure connections, and a standout underhood appearance. Every set is engineered, hand-built, and hand-tested in the USA.
