Buying Guide

Spark plug wires matter. Get the right wires for your car.

Many owners say new wires boost power. Others notice better gas mileage.

Here’s what to think about when you shop:

  • Engine Type: Know your engine. Some wires fit specific engines. Double-check compatibility before purchase.

  • Wire Length: Wires must reach. Measure old wires for correct length. Too short or long causes problems.

  • Wire Diameter: Thicker isn’t always better. Match diameter to your system’s needs. Bigger wires can handle more power.

  • Material: Heat kills wires. Pick heat-resistant materials. Silicone and fiberglass are good choices.

  • Terminal Design: Terminals connect wires to plugs. They need to be strong and rust-proof. Good terminals ensure a good spark.

  • Insulation: Good insulation is a must. It stops electricity from leaking. Look for high dielectric materials.

  • Warranty: Warranties offer peace of mind. They show the maker trusts their product. Check the warranty terms before you buy.
