If you're looking to fine-tune your ride's performance, these screw-on plumb-back fittings are a solid choice. They’re designed to fit any universal blow-off valve, which means you can easily swap them in without a hassle. I’ve used the 5230 GFB Recirc Outlet Male fitting, and it works perfectly with a 30mm (or 1-1/8") ID hose. It’s a game changer for keeping that boost pressure in check while ensuring your setup stays nice and quiet.
What I really appreciate about these fittings is their versatility. Whether you're running a daily driver or a weekend warrior, having the right fitting can make all the difference. They screw on easily, and I’ve never had any issues with leaks or fitment. Plus, the quality feels solid; you can tell they’ve been built to last.
So, if you're tired of the loud venting noises that come with some setups, give these a shot. They’ll keep your system recirculating and working efficiently, which is what we all want, right? Just make sure you’ve got the right hose size, and you’re good to go. Trust me, your engine will thank you for it.
