Post-MAF Pipe Kit

The GrimmSpeed Post-MAF Pipe Kit is engineered to enhance the performance of your 2022+ Subaru WRX by replacing the restrictive factory plastic post-MAF pipe. This kit utilizes larger diameter, CNC mandrel-bent aluminum tubing with large radius bends to minimize restriction and maximize the efficiency of your stock airbox. The design aims to improve airflow, potentially resulting in faster spool times and a more engaging driving experience. Constructed with durability in mind, the pipe features a textured black powdercoat finish for added resilience against the elements. The kit is designed to maintain OEM emissions standards by retaining the essential hydro-carbon filter found in the 2022+ WRX models. The connections utilize 4-ply stainless steel-reinforced silicone, offering a balance of extreme durability and flexibility. Installation is straightforward, with an OEM fitment that requires no modification to your vehicle. This makes it an accessible upgrade for owners looking to achieve an OEM+ look and improved performance. The kit is specifically designed for the 2022+ Subaru WRX, including all trims, and is compatible with the FA24 engine. No tuning is required, even when paired with a GrimmSpeed DRY-CON Panel Air Filter for optimal performance gains.
