The latest kit from the silicone labs at Forge Motorsport is yet another quality part for the perennially tuneable Subaru WRX/STI GR engine. As history tells us, this will always be one of the scene’s most fettled cars, so anything that can help to keep a lid on coolant temperatures is a good idea. This impressive and all-new seven-piece coolant kit created by the Gloucestershire firm has been designed to cope with the latest OAT coolant formulations used in modern engines.

Subaru is one of many manufacturers that has been quick to adopt the latest OAT (or Organic Acid Technology) coolants. These are used in most modern cars and have superseded the previous generation of methanol and Ethylene Glycol mixtures. OAT coolants have an extended service life of around five-years use under normal conditions and while standard silicone hoses have a high resistance to the old Ethylene Glycol coolants, they can quickly deteriorate, if not protected, when OAT coolants are used. For this reason, these new Forge hoses have an internal lining of Fluoro-silicone to protect and ensure the longevity of the hose.

As well as being specifically designed to work with the latest OAT coolants, all Forge hoses are designed to withstand much higher pressures and temperatures than any original equipment hose, they are also available in three different colourways, including the discreet looking black finish for those looking to create a real ‘OEM+’ engine bay, or red and blue for those that aren’t…

Each kit has been designed and developed in the UK, using fabric reinforcement inside the finest quality European-sourced silicone. As well as significantly enhancing the under-bonnet appearance of any cherished Subaru engine, these hoses will dramatically outlast the original parts.

Not only do these hoses make a great insurance policy on a standard car, but they’re also an essential upgrade on a remapped or modified machine, or SDR V-Storm, for example. Let’s face it, most WRXs are going to get a little extra boost, aren’t they? – making these hoses a performance essential.

The hoses shown cost  £138.92 inc VAT for each complete kit – including all stainless steel hose clamps for every hose.
