Replace your restrictive factory intake system with the PRIME Silicone Performance Intake Kit featuring the highest quality filters available on the market. The S&B intake filters greatly increase flow in the mid to upper RPM range while introducing a more aggressive engine note. Gains of up to 60whp can be realized by replacing the restrictive factory intake inlets with this bolt on kit.
 
The PRIME passenger side inlet upgrade kit relocates your coolant reservoir to the driver side while providing a more direct, high flowing intake path for your turbos. The passenger side kit is 2.5″ and is made from a one piece reinforced high temperature silicone. This kit works with any chargepipe available without restriction due to our unique mounting brackets. This kit will only work with LHD 135i/335i/335is.
Our inlet kit include everything you need to replace the restrictive OEM inlets with our upgraded higher flowing set, including relocation brackets, filters, vacuum/coolant hoses, and one piece, steel wire reinforced silicone tubing.
