Purchase Kuehl Reliability Packages for Porsche 911 and 930 models. Our Reliability Packages include everything you need to improve the integrity and cooling of your air conditioning system at an affordable price. Reliability Packages don’t include Kuehl Fender Condensers.

Info

The Kuehl Reliability Package Upgrades address all of the common issues found with the Porsche 911 and 930 stock factory air conditioning system. These packages include replacement parts for nearly every component in your air conditioning system. Your Porsche’s AC system will be much more reliable after installing one of these packages. You will also notice colder air conditioning and no more refrigerant loss.

Reliability Package Includes

New Barrier AC Hoses

Your stock hoses are leaking refrigerant constantly because they are non-barrier hoses. This old fashion hose line slowly leaks (permeates) refrigerant through it’s skin overtime; this is not a design flaw nor was the design intended to do so, it was simply the way things were. Kuehl Barrier Hoses provide 5 layers of protection to minimize refrigerant leakage. System models with o-rings tend to leak after 25 years. All Reliability Package Upgrades include a new set of HBNR type o-rings.

New Kuehl Drier

The receiver drier is critical component to your a/c system. The drier is as important as your oil filter is to your engine. It consists of a steel tank, a filter, desiccant bag (drying agent) and a side mounted site glass.  The Kuehl drier uses XH9 type desiccant which is compatible with R134a and R12 refrigerants.

New Low-High Pressure Switch

All Kuehl Reliability Packages 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 special features helps to prevent compressor failure and is required by the EPA in certain State applications.

New Kuehl High Performance Serpentine Evaporator

OEM style Tube & Fin evaporators are prone to leakage. There are multiple brazed joints and the cooling fins were not securely bonded to the cooling tubes. The Kuehl Serpentine Evaporator has only 2 brazed joints. The cooling fins are permanently brazed to the serpentine extruded tube.

The Kuehl High Performance Serpentine Evaporator for the Porsche 911 and Porsche 930 has more surface area than the OEM and is lighter too. In a recent head to head controlled test, the original Kuehl out performed the OEM evaporator as well as an inexpensive copy. The Kuehl unit simply has greater surface area yielding more btu’s per square inch than any other

New Kuehl High Performance Parallel Flow Front Condenser

This new condenser utilizes the latest generation “plate and fin” tubing technology. The benefits of the Kuehl design lay in its twin (double) manifolds with thin multi-channel extrusions and high fin density, a newer more efficient plate & fin construction which yields higher BTU dispersion through greater fin density and increased refrigerant tube count.

New Kuehl Center Vent

Griffiths designed the Kuehl Center vent exclusively for your 911. The original Kuehl Vent replaces the factory “bow tie” floor vent located on the lower bulkhead (fire wall) in front of your AC floor console. The Kuehl Vent redirects the colder air from the bulkhead “floor” vent directly to you (rather than on your feet). Bulkhead air temperatures can be 5 F degrees colder than the sun baked dash vent temps.

The single Kuehl Vent installs in just 15 minutes (it’s pre-assembled for you). This is a non-invasive installation (meaning no cutting or drilling or gluing) using just two wrenches. Kuehl Vent does not interfere with the ashtray operation. And best of all the Kuehl Vent design is as close to OEM as you can get (probably better), and it belongs there. Get more colder air with the Kuehl Vent.

Compressors

Griffiths Reliability Packages are available both with and without new compressors.
