Being new to the Subaru EJ25 engine and its features, I was not aware of the Subaru approach to oil cooling such as featured here: http://www.licmotorsports.com/produc...sti_21311aa051

On the face of it, this is a slick solution and approach to the problem, since it uses engine coolant already cooled and circulating to cool the oil and fits between the oil filter and the bottom of the block. Though I appreciate the efficiency of this, I will admit to being a little skeptical of those systems in which a minor defect in the device could have catastrophic consequences. On my new engine, which is an STi block with Tomei dual-scroll headers, it fits great.

However, I would be interested in the opinions of those with high performance/racing applications of the WRX/STi platform as to the effectiveness of this unit. One of the factors that makes me ask is that I haven't seen one in anyone's posts or build threads.

Thanks
