As part of IAG's ongoing Subaru EJ Series engine performance program, we have developed a stainless steel AN breather fitting set with a focus on performance and serviceability. Our Stainless Steel AN Breather Kit allows you to use lightweight racing hoses with AN fittings which are easier as well as faster to remove and reinstall when you need to service your EJ at the track. AN fittings also provide a more reliable hose connection on the engine during competition. Combining the AN Breather Kit with our Race AOS will give you a complete AN breather hose solution. The breather set includes six stainless steel fittings designed to be press fit into the breather ports located on the block and valve covers. The set also includes two AN caps for installation as well as Loctite 620 high temp sleeve locker. *This part is not a direct bolt-on. Installing the AN Breather Fitting Set requires custom AN hoses, a Race AOS and is recommended to have an experienced technician properly press the breather fittings in place. IAG does not currently offer installation instructions for this part.
*This product was originally designed for use with the IAG Race Series AOS so that racecars could use AN fittings at the AOS as well as the breather ports. The product can be used with IAG Competition Series and Street Series AOS's however, you would not use AN fittings at the AOS. Race Series AOS will be available in the summer of 2018.
