The IAG Performance Replacement Blow-Off Valve (BOV) Elbow is designed for 2002–2007 WRX and 2004–2021 STI models. Machined from high-quality billet aluminum, this direct replacement for the factory elbow—which is not sold separately by Subaru—offers both durability and precision fitment.
Engineered with 180° rotational flexibility, the IAG elbow allows for easy positioning when used with aftermarket intercoolers or custom setups. Each elbow comes complete with a new rubber o-ring and stainless steel screws, ensuring a secure, leak-free installation and reliable performance under boost.
