Specs & Features

• Crush-Proof Construction: Built with 4-ply silicone and an internal steel wire skeleton to prevent hose collapse under high-vacuum peak boost.
• The "True Taper" Advantage: specialized geometry creates a smooth, gradual transition for airflow, eliminating the turbulence caused by the "stepped" design of the stock part.
• Thermal Defense: Thicker silicone construction actively rejects engine bay heat, keeping intake air temperatures lower than the heat-soaking factory plastic.
• Direct Fitment: Precision engineered to replace the OEM unit seamlessly using included steel sleeves and hardware—no hacking required.
• Style Options: Available in classic COBB Blue or the stealthy, under-the-radar Black.
• Critical Note: Tuning is Required. This part flows so much better than stock that you must use appropriate COBB Accessport OTS Maps to ensure safe engine operation.

Product Description

Let’s be real about the factory inlet pipe: it is a clunky piece of plastic and rubber that becomes a major bottleneck the moment you start adding power. The biggest issue? The "milkshake effect." Just like a paper straw collapsing when you drink a thick shake too fast, the stock rubber hose can actually suck shut and collapse under the intense vacuum created by the turbo.

COBB Tuning solved this by embedding a steel wire reinforcement directly into the 4-ply silicone. This ensures the hose maintains its shape and volume even when the turbo is demanding maximum airflow.

But it isn't just about durability; it's about flow dynamics. The OEM part has sudden "steps" or neck-downs that cause air turbulence, slowing down the velocity before it hits the compressor wheel. COBB Tuning utilizes a True Taper design, which creates a perfectly smooth, funnel-like path from the intake to the turbo. This means your engine gets a laminar stream of cool air, resulting in sharper throttle response and more consistent power delivery. Whether you choose the signature Blue or the sleeper Stealth Black, you are getting a part that fixes a factory flaw and sets the stage for big power. Don't let a floppy rubber hose be the reason you lose a race. Make the switch to COBB and let that turbo sing.
