7.5" Stepped Race Front Mount Intercooler

The VRSF 7.5" Stepped Race Intercooler is a high-performance front-mount intercooler designed to replace the factory unit in 2007-2012 BMW 135i, 335i, and 335is models equipped with N54 and N55 engines. This upgrade is crucial for drivers seeking to maximize the potential of tuned engines running increased boost levels, as it effectively prevents heat soak and maintains lower intake temperatures. By keeping charge air cool, the intercooler ensures consistent power delivery, reduces the risk of pre-detonation and knock, and improves overall engine reliability. The core utilizes an ultra-high density, 1100hp-rated custom bar and plate design with a staggered and offset fin pack, meticulously tuned to offer superior cooling with minimal pressure drop. This construction is also significantly more durable than the OEM tube-and-fin core, providing better resistance to debris. Constructed with CFD-engineered cast aluminum end tanks, this intercooler promotes improved airflow over traditional sheet metal designs and offers enhanced durability through its one-piece, seamless construction. The bright silver coating protects against corrosion and the elements. Installation is designed to be straightforward, with an estimated time of under 2.5 hours, and includes custom molded couplers, stainless steel t-bolt clamps, and all necessary hardware. Notably, it retains the factory fan shroud via integrated tabs. However, trimming of the black plastic shroud behind the bumper is required, though bumper trimming is not. This intercooler is compatible with Left Hand Drive (LHD), Right Hand Drive (RHD), and all XI models. VRSF backs this intercooler with a lifetime warranty and a satisfaction guarantee, covering fitment and defects.
