RCM Engine Oil & Power Steering Cooler Kit (08-14 WRX/STI)

Engine oil teperatures are key to maintaining a healthy engine as well as performance. Under hard driving conditions oil temperatures naturally raise as a greater heat is generated from the faster moving engine components. With oil temperatures greatly increased the viscosity of the oil can thin lessening its ability to efficiently lubricate precious engine components which eventually leads to premature wear and in extreme cases engine failure.

Our cooler kit has been specifically designed to combat the above problem and ensure your temperatures maintain a safe level. Choosing only the best possible components our kit not only cures rising engine temperatures but is built to last with no compromise on quality.

Each RCM oil cooler kit is supplied with the choice of either a 10 or 19 Row Setrab Core. Setrab's cores are renowned for strength and quality, with working temperatures from -40°C to 150°C and a maximum burst pressure of 37 Bar(g), these coolers are more than qualified for the job and will provide long term reliability as well as consistent performance.

Leading Aeropquip manufacturers Goodridge produce pre-assembled lines to our specification using their latest -8 200 Series stainless steel braided nitrile hose. Designed to Goodridges exacting specifications this hose has been supplied to motorsport racing champions for many years. 200 Hose provides essential protection and resistance to high pressure, temperature, vibration, fire risks and chafing. It is constructed of a seamless synthetic CPE inner with an integral stainless steel braid and a high tensile stainless steel outer braid. 200 Series hose has the highest corrosion and fire resistance threshold of any stainless braided nitrile hose available, but lets not stop there! In addition our lines are covered with a silicone covered sleeve which acts as a secondary fire retardant, insulator and chafe protector. With the fireproof sleeve having operating temperatures from -54°C to 260°C and short term fire protection of up to an impressive 1090°C our lines surpass all safety, reliability and performance requirements. To finish, each line end is fitted with a Goodridge re-usable alloy fitting precisely engineered to fit 200 Series Hose. Their Aerospace standard Triple Seal/Double O-ring nitrile, cutter design ensures a secure, leak free connection every time and allow for any required alignment with their 360-degree swivel ends.

The final vital component is the Thermostatically Controlled Oil Sandwich Plate. Manufactured so the oil lines can be directed at multiple angles the plate proudly offers the best possible fitting for all variants of exhaust manifolds (including Twin Scroll, Equal Length and Un-Equal Length), something not offered by most competitors. Additionally there are two spare ports for those who wish to run oil temperature and pressure sensors (also supplied with blanks should these not be required) along with a replacement extended union to allow fitment of both the plate and oil filter. The built in thermostat opens at 85°C allowing ample engine temperatures to be reached before further engine oil cooling is required.

In warm areas of the world power steering pump failures can be a common occurrence due to components overheating (even through normal everyday driving). This is also a common issue found on many race cars due to greater demands on the steering system which in turn generates higher temperatures, thinning your power steering fluid which then causes premature wear to the bearings inside the pump.

Our Power Steering Cooler Kit has been specifically designed to combat the above problem and ensure your temperatures maintain a safe level. Choosing only the best possible components our kit not only cures rising power steering fluid temperatures but is built to last with no compromise on quality.

During the design process of both our Power Steering & Engine Oil Cooler Kit, location and fitting played an important factor. Naturally the core's needed to catch as much cold flowing air as possible in order for the cooling effect to be at its best, additionally it would be advantageous if the cooler could locate somewhere on the vehicle where it would not be necessary to drill into the body. After much time spent in R&D followed by a number of dyno and road tests the perfect solution was formed. The mounting brackets for both coolers fit snuggly behind the front upper grill using existing mounting points and clips already found present on the vehicle. The cooler cores can be fitted within minutes, but perhaps even more beneficial is its access to a vast amount of fast moving cold air.

Each RCM Power Steering Cooler Kit is supplied with a 10 Row Setrab Core. Setrab's cores are renowned for strength and quality, with working temperatures from -40°C to 150°C and a maximum burst pressure of 37 Bar(g), these coolers are more than qualified for the job and will provide long term reliability as well as consistent performance.

Goodridge produce pre-assembled lines to our specification using their latest -6 210 Series hose. "210 Series" is a new development, based on the conventional 200 series stainless steel braided Nitrile hose, widely used in all forms of racing & our Oil Cooler Kits. The 210 series has a lightweight fibre braid, with high abrasion resistance, and is ideal for carrying power steering fluid. It is the perfect solution as a lightweight alternative to 200 series, where the robust stainless steel braid is not necessary, and weight saving is paramount. To finish, each line end is fitted with a Goodridge re-usable alloy fitting precisely engineered to fit 200 Series Hose. Their Aerospace standard Triple Seal/Double O-ring nitrile, cutter design ensures a secure, leak free connection every time and allow for any required alignment with their 360-degree swivel ends.

Each kit is supplied with a choice of either a "Black Hardened Powder coated" Steel or "Brushed Finish" Stainless Steel mounting bracket. Laser cut and skillfully folded into position the brackets also feature pressed fixings for the oil cooler core to attach to and swaged holes to reduce weight and improve rigidity and strength.
