The OEM Porsche lead acid batteries for MFI 911s are heavy, and often leak acid into the front of the car - NOT what you want - especially if you just restored it!
The MFI 911s, using these stock batteries, can experience slow startup, surge/hesitation at cruising speed, and unbalanced fuel mixture.
For years we've installed Odyssey batteries on all of our projects at Patrick Motorsports.
The advantages are crystal clear:
**No more leaks: Odyssey batteries are AGM (Absorbent Glass Mat) dry cell type. They have no liquid acid inside - if you cracked one open nothing would leak out!
**Lightweight: Due to having no battery acid inside, they are considerably lighter than the OEM Porsche batteries.
**Faster, Reliable Startup: Cold starts are a breeze with Odyssey batteries, as they operate at a higher power level.
**Increased Ignition Output: This is the #1 reason to upgrade. The MFI Porsches take full advantage of the higher ignition output, resulting in better combustion, smoother performance, and lower emissions.
Fits 1969 1970 1971 1972 1973 dual battery 911 models.
