Why this intake works on the S58

The factory setup on the S58 can be restrictive when airflow demand rises. MST’s 4 inch pipework increases cross-sectional area, the heat shield helps isolate the filter from engine bay temperatures, and the high-flow dry element keeps pressure drop low while maintaining filtration. The result is a free-breathing induction path that complements spirited road driving and track work alike.

What’s in the box

• Black powder-coated heat shield
• Black powder-coated 4 inch aluminium intake pipe
• Red dry pleated performance cone filter
• Quality silicone joiner and clamps
• Complete fitting hardware and instructions
