Subaru WRX COBB TMIC Coupler Black Silicone 08-21 Forester Legacy 724455

This is the small fix that saves you a boost leak headache — a genuine COBB Tuning TMIC coupler, part 724455, replacing the factory hose between your top mount intercooler and throttle body. Factory rubber gets brittle and cracks over time — this one doesn't.

Built from durable 4-ply silicone in a stealth black finish with the COBB logo pad printed right on it, this coupler holds boost pressure reliably whether you're running stock or a tuned setup, and it works with both your stock top mount intercooler or an aftermarket one. Comes with lined worm drive clamps included, so it's a genuine drop-in replacement — no separate hardware order needed.

But this isn't just about a boost leak. It's about an engine bay that's actually tidy and reliable — the difference between chasing a mystery leak down the road and knowing this connection is solid. Whether you're daily driving or pushing more boost, this coupler does exactly that.
