Griffiths offers Porsche 911 AC Compressors & Upgrade Kits for the Porsche 911 Air Conditioning system. Your compressor replacement options vary depending on the year of your Porsche.
Porsche 911 (1968-1983) Compressor Replacement Options
When replacing the compressor on a Porsche 911 from 1968 – 1983, you have 2 options.
- Replace the compressor with a factory OEM York compressor.
- Alternatively, you can upgrade the compressor to an aftermarket Kuehl-507 Rotary Piston Compressor.
OEM York Compressor
The Porsche 911 used various a/c systems in the early years, some made by Delanair (later became part of VPC or Volkswagen Products Corp), another firm called Coolaire and Behr. Earliest systems used a Tecumseh 5cu.in. and York 6cu.in. Around 1971 the York 10cu.in. (size shown in the right side picture) became common in the Porsche 911 and 930 up through 1983 (in 1983 the euro 930 starting using the Nippondenso). The York design is uses a crankshaft type piston mechanism. Griffiths stocks brand “new” York 10cu.in. compressors, available without clutch.
Kuehl 507 Rotary Piston Compressor Upgrade Kits
Our Kuehl-507 Porsche 911 and Porsche 930 upgrade kits (for 911’s prior to 1984 and turbo’s prior to 1983) offer many benefits over the original York compressor found on the early Porsche 911 and Porsche 930 up through 1983.
The Kuehl 507 compressor uses an updated “wobble-plate” design, similar to a Sanden compressor. The wobble-plate moves five smaller pistons, compared to the York which uses a crankshaft to move two large pistons. The Kuehl 507 compressor requires less horse power to turn and is a better match for the condenser area. Griffiths’ Kuehl 507 upgrade kit also takes up less space in the engine compartment. It runs noticeably smoother & quieter than the York, and also improves system efficiency.
The Kuehl 507 compressor upgrade and its Kuehl Kwick mounting bracket bolt directly to the original York sub or base plate, which saves you considerable time and knuckle scraping during installation. Our Kuehl-507 upgrade kits are available in 3 configurations to match your objectives & budget. These kits range from bare bones compressor w/ essential replacements to complete system overhaul, including new upgraded Kuehl AC Barrier Hoses.
All Kuehl-507 kits include our exclusive “high-low” pressure cut-out switch feature. The switch prevents the system from running when the high side pressure is either too low or too high. This helps prevent compressor failure and is required by the EPA in some states. We offer Kuehl-507 upgrade kits in R12 or R134a. We also offer Kuehl-507 upgrade kits bundled with our Kuehl Condenser Systems in a larger package for additional cost savings.
Porsche 911 (1984-1989) Compressor Replacement
We recommend our Nippondenso compressor with clutch for the Porsche 911, years 1984-1989. It is a direct replacement for the original Nippondenso compressor. The pumping capacity matches that of the OEM and it bolts right on.
