The S series of 6 phase hairpin alternators offer a great punch in a compact and durable package. A side output stud and seamless rear cover with a side output plug allow for better clearance from the back of the alternator to the front of the engine and a smooth appearance. A single wire on the provided pigtail gets connected to any ignition switched 12V+ source to turn the alternator on and off with the ignition switch. Simply run a properly sized positive and ground cable from the alternator to the terminals of the battery and the alternator will work perfectly, regardless of what kind of wiring harness you have.
*** Please note that engine idle RPM's will usually need increased on these larger 320-amp versions for proper charging at vehicle idle RPM's. The 320-amp option is considered a max-effort alternator whereas the 170- and 240-amp versions are lower idle RPM friendly and streetable.
*** Will need to purchase 8-rib pulley if using on factory supercharged 3.8L engines ***
