Stock resistor-core plug wires turn part of your spark energy into heat before it ever reaches the plug. Granatelli Motor Sports 0-Ohm spark plug wires use a solid stainless steel conductor with zero ohms of resistance, so the full output of your ignition gets to the spark plug.
Low resistance usually means radio and electronics noise, but our patented suppression design (U.S. Patent 7,185,622) eliminates RFI/EMI interference, so these wires are OBD-II computer safe and work with fuel-injected street cars and race cars alike.
Designed for 1999-2004 Buick Regal 3.8L, 2000-2004 Chevrolet Impala 3.8L, 2000-2003 Chevrolet Lumina 3.8L and 2001-2008 Pontiac Grand Prix 3.8L. Always confirm fitment with the eBay compatibility chart before ordering.
Will these interfere with my radio or engine computer? No. The patented suppression design eliminates RFI/EMI interference and the wires are OBD-II computer safe.
Do they work on stock engines? Yes. They are a direct replacement for the factory wires on street engines and hold up on race engines too.
