1High Compatibility: The ignition coil can fit and work well with replacement for Chevy V8 engines, replacement for Ford V8 engines, replacement for Olds V8 engines, replacement for Pontiac V8 engines, and replacement for Mopar V8 engines. 2Wide Application: The high output ignition coil is extensively suitable for most street, strip, circle track, and drag racing applications to better meet your needs. 3Higher Output: The red high output electric core ignition coil could offer 70% more spark than ordinary coils and is much more reliable, greatly bring you more convenience. 4Wire Windings: There are large gauge wire windings in the Internal coil which can provide maximum spark current and voltage with better heat dissipation at high rpm. 5High Performance: The coil is ideal for working with capacitive discharge (CD) ignition systems, because screw on connectors and a high tension tower can minimised High voltage arcing.
