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.
