A sealed, locking connector keeps the minimal wiring of the 6A tidy for a clean installation in all applications. It can be run on 4, 6 and 8 cylinder engines with a 12 volt negative ground electrical system and can be triggered with breaker points, an electronic amplifier or magnetic pickups.
The Digital 6A is a microprocessor controlled, capacitive discharge ignition that multi sparks up to 3,000 RPM providing easy starts, a clean, smooth idle and quick throttle response by optimizing your engines efficiency. Above 3,000 RPM, a single spark stays lit for up to 20⁰ of crankshaft rotation ensuring a complete burn of the air / fuel mixture in every cylinder.
If you're looking to improve the performance of your modified mill, we have the answer. Whether you've done a cam swap, or bolted on a carb, intake and headers… the 6A is a surefire way to harness all the ponies under your hood.
