Improve air flow and gain more power! Our post MAF hose kit offers a smoother and more consistent air delivery.
Our post MAF hoses are a big upgrade from the OEM ones with two key features. First, they have a super - smooth inner surface. We've removed those pockets from the OE's corrugated folds. Made of 4 - ply silicone and reinforced with an internal stainless - steel wire, these hoses are flexible and keep their strong structure. They maximize air flow, are easy to install, and won't collapse under vacuum. And unlike some competitors' products, they're built to last.
Second, the hoses have tapered end portions. This ensures that the inner diameter matches the OEM air box and turbo inlet perfectly. A mismatched diameter can mess up the air flow and create small whirlwinds. Our design prevents these problems.
METHODOLOGY:
To improve on the existing part, we found its flaws. The OEM rubber hoses have sharp angles and corrugated folds, which cause uneven air pressure. Our hose design has a minimal curve and a smooth interior, leading to more consistent air flow to the turbo.
The tapered part is also crucial for even flow. A comparison shows that our tapered hose reduces turbulence better than non - tapered ones.
