What makes this CSF oil cooler different from older OEM RS oil coolers?

This CSF cooler is designed to be more robust and durable than the original 30-year-old Porsche RS oil coolers. It can withstand higher burst pressures and is built to handle vibration and debris, making it a more reliable and affordable alternative.

What type of fittings does this oil cooler use, and what adapters are needed?

The cooler uses universal style M22 x 1.50 female fittings. You will need to use M30, -16AN, or -12AN union adapters to connect your oil lines to the cooler.

Can this oil cooler be used in applications other than a 1989 and older Porsche 911/930?

Yes, while it was originally designed for specific Porsche models and bumper styles, its universal nature and adaptable fittings make it suitable for a variety of custom applications where effective oil cooling is needed.

Product Details

If you're building a classic Porsche 911 or 930, especially one with an IROC-style bumper, keeping oil temperatures in check is crucial for engine longevity. This CSF Universal Dual-Pass Oil Cooler is designed to fit that need, offering a modern solution to a classic challenge. It's a dual-pass design, meaning the oil travels through the core twice, giving it more time to shed heat compared to a single-pass unit. This is particularly important for air-cooled Porsches where managing heat is a constant concern.

What sets this CSF cooler apart from older designs is its construction and adaptability. Unlike the original Porsche RS oil coolers, which are rare and expensive, this unit is built to be more robust and durable. It can handle higher burst pressures and is designed to withstand the vibration and potential debris found in areas like the front fascia. The M22 x 1.5 female fittings are located on the same side with a slight 15-degree angle, which makes routing oil lines much simpler than older banjo-style fittings. This design also helps avoid stacking multiple coolers, which can restrict airflow to other vital components.

This cooler is well-suited for custom applications beyond the classic 911/930. Its dimensions and dual-pass configuration make it a strong option for various builds where space is tight but effective oil cooling is a must. It features 10 rows of high-pressure bar-and-plate cooling, and it's designed to work with M30, -16AN, or -12AN union adapters, giving you flexibility in your plumbing setup. While it's designed as a front-mount center oil cooler for specific Porsche bumpers, its universal nature means it can be adapted to many projects needing a reliable way to manage oil temperature.
