This is our cream of the crop, top of the line. These 10.5's are 125 ohm/foot. That tells you alone how premium of a wire this is. Stock OEM wires range from 500 to 600 ohm.
These also come with premium matching screw down style spark plug wire separators. Each wire is also marked per cylinder so you know which wire goes where.
More heat resistant, far better look, and best of all added performance.

On a dyno run with no differences except for the spark plug wires we found an extra 4 horsepower to the wheels compared to MSD wires and an extra 5.7 horsepower compared to the stock OEM wires.
These work on all GM 3800 Series II and Series III engines. Which is 1997+ Pontiac Grand Prix's, Buick Regals, Pontiac Bonneville's, Etc. Works on the Australian Holden Commodore also! Should work on many other GM V6 cars, but these were especially made for the Supercharged and naturally aspirated 3800 series II engines. People have also bought and used them on the 3400 and 3100 V6 GM Engines.
