Oil Radiators / Heat Exchangers

Air duct diverter plate centre oil cooler. 



Fits:
Porsche 911 / 930 - 1974 to 1989

Optimize Airflow for Maximum Cooling Efficiency
Enhance your center-mount oil cooler setup with this air duct, designed to sit behind the cooler. It creates a streamlined exit path for air, significantly improving airflow and boosting cooling performance.

RS/RSR Diverter Plate Replica
This oil cooler panel is a precise replica of the original RS/RSR diverter plate. Installed by cutting out the front of the tub and welding the panel in place, it securely mounts the oil cooler. Air enters from the front, passes through the cooler, and is efficiently diverted downward. Some trimming may be required for a perfect fit. Compatible with 1974-89 911/912/930 models.

Universal dual-pass oil cooler with direct fitment for Porsche 911 center front oil cooler (RS Style).
Custom end tanks with a 45° chamfer
M22 x 1.5 connections - 22" L x 4.75" H x 2.25" W
Dual pass for increased oil cooling

Fits
911/930 models up to 1989

RS style bar and plate oil coolers for air-cooled Porsche 911/930 models (up to 1989). This oil cooler is a direct-fit performance replacement for the original Porsche items but they can also be used as heavy duty universal units

These new oil coolers have custom end tanks with a 45° chamfered front angle, allowing them to fit flush inside '73-style RS/RSR bumpers. The fittings are pointed straight back. For best airflow and highest performance, CSF recommends cutting the front tub to allow for proper air flow, exiting behind the oil cooler and underneath the vehicle. Cutting the front tub will also give clearance to allow adding a rear fan shroud to pull more air through the cooler at slower speeds or while idling

Product Features:

•High Efficiency & Rugged Durability Bar/Plate Design

• M22 x 1.5 Inlet/Outlet Connections
• "Aero-Flow" Bar Design for Lightweight, Strength, and Maximum Flow
• Triangular flush mounting bolts on both top & bottom (M8x1.25)
• Satin Black Finish for Extreme Protection Against Corrosion and Debris
• Pressure Tested at 120psi

After 2+ years of development and 4 rounds of prototypes, the world debut of the CSF Porsche 911/930 Engine Oil Cooler at Rennsport Reunion 2023 was met with resounding enthusiasm. Air-cooled enthusiasts know the struggles associated with the oil cooler located on the engine block of the old flat six motor. CSF’s highly anticipated new release is arguably the most important modern engine upgrade to be released for the 911 in years.
While the original design was effective at the time, they have not aged well. On top of that, there have been no updates to the design and original replacement units can be hard to come by. When the CSF 911 was being built, CSF realized this was a much needed part for the air-cooled community and set out to design something special.

The old original coolers aren’t the only issue though. CSF has gotten many first hand reports of brand new OE coolers from Porsche’s revamped “Porsche Classic” Catalogue leaking within a few months of installation. Apparently the new items available from Porsche are not built as well as the original Behr coolers. CSF has now brought to market a modern OEM+ solution to this vintage design.

The high-performance core uses 7 cooling tubes with 8 rows of fins. Between the ultra efficient fin design and high flow tubes, the CSF cooler is ~10% more efficient than a brand new OE unit and up to 25% more efficient than a used unit.

Because the base plate of the cooler is also a common problem area, CSF sought to improve this area as much as possible. Instead of the original cast design, the CSF cooler uses a CNC machined billet aluminum plate. This offers a perfectly flat mounting surface which is both stronger and more resistant to warping over time. You’ll also notice a special helix design which adds strength while keeping weight at a minimum.

Each unit is Individually Leak and Pressure Tested with a 10 year warranty
New OEM coolers from Porsche are extremely scarce/hard to source and cost $1,300+

Radiator oil cooler rubber buffer.
The Porsche 93020723900 / 93020723901 / 93020723902 Bonded Rubber Buffers are factory-original components designed to mount and stabilize the oil cooler assembly in air-cooled Porsche 911 and Turbo models. Each mount uses a precision-bonded rubber and steel design that isolates vibration and absorbs engine movement, protecting the oil cooler and its lines from stress and damage.
Sold individually, 3 required per car

Fits:
Porsche 911 1984 - 1989

Diagram Ref No 14.

Located between the oil cooler housing and the chassis or engine bracket, these buffers play a vital role in maintaining correct alignment and reducing vibration throughout the cooling system. Over time, exposure to heat, oil, and vibration can cause the rubber to harden or crack. Replacing with genuine Porsche parts restores factory stability, vibration isolation, and long-term reliability.

Radiator oil cooler rubber buffer.
This replacement buffer is a high-quality replacement for the factory bonded-rubber mounts used to support the oil cooler assembly in air-cooled Porsche engines. It helps isolate vibration, maintain correct alignment, and protect the cooler and adjoining hardware.
Sold each, required 3 per car.

Fits:
Porsche 911 1984 - 1989

Diagram Ref No 14.

This is a rubber buffer or mount (often bonded to metal inserts) used to cushion and secure the oil cooler assembly relative to the engine or chassis. It absorbs vibration, prevents metal-to-metal contact, and keeps the cooler in its correct position. It helps avoid stresses on oil cooler brackets, lines, and mating surfaces by providing a flexible mounting point.

Replaces: Porsche 930.207.239.00 / 930.207.239.01 / 930.207.239.02
Position: Between oil cooler and engine or chassis mount — isolates vibration and supports alignment
Function: Absorbs vibration and engine movement, prevents stress on oil cooler lines and brackets
Installation: Direct-fit OE replacement — install as a set for best results
Maintenance Tip: Replace when rubber hardens, cracks, or separates from metal housing

Over time, the rubber in the buffer mount degrades due to heat, oil exposure, ozone, vibration, and fatigue. It may harden, crack, shrink, or separate from its bonded metal insert. A failed mount lets the oil cooler shift or vibrate more than designed, putting strain on cooler hoses, brackets, and mounting flanges — potentially leading to leaks or damage. Excessive vibration may cause noise, misalignment, or premature fatigue of supporting parts. You should replace this buffer when you notice damage or deterioration, when removing or servicing the oil cooler, or as preventive maintenance on high-mileage engines.
