ZZP LS4 10mm Performance Ignition Spark Plug Wires

These ZZP LS4 10MM Performance Ignition Spark Plug Wires have been improved to be more durable and give you a more powerful spark for your money.  ZZP wires have a lower resistance than factory wires but they are not directly comparable to other wires on the market.  Metal changes resistance based on temperature.  ZZP wires are designed so that during use the resistance increases at a different rate than a standard metal core wire. We do this after extensive testing with the factory coils and ZZP coils.  We are the only company testing in this fashion that we know of and below you can see the results of our wires compared to the competitions wires.  Remember that just because a wire appears the same, even measures the same, doesn't make it the same.  You need to test in real world conditions.  More heat resistant, a far better look, and best of all added performance. On a dyno run with no other changes except for the spark plug wires we found an extra 4 horsepower to the wheels compar
