The OEM Porsche lead acid batteries are heavy, and can leak acid - NOT what you want - especially if you just restored the car!
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 especially take full advantage of the higher ignition output, resulting in better combustion, smoother performance, and lower emissions.
