DETAILS

• Color: Red silicone
• Replaces factory post-MAF hoses
• Higher-grade than OEM rubber
• Fitment: 2015-2021 Subaru WRX

The post-MAF hoses on the 2015-2021 Subaru WRX are under boost pressure and see elevated temperatures. OEM rubber hardens and develops micro-cracks over time, causing small boost leaks that are difficult to locate.

The GrimmSpeed red silicone hoses maintain their compliance and sealing characteristics significantly longer than OEM rubber. The red color provides a visual upgrade alongside the functional improvement.
