Stage 2 Hardware Kit

The VRSF Stage 2 N55 F-Chassis Hardware Package is engineered to unlock reliable Stage 2 power for specific BMW models. This comprehensive kit is designed for the BMW M135i (F20, F21), M235i (F22), 335i (F30), and M2 (F87) equipped with the N55 engine. The package includes a VRSF 5-inch intercooler upgrade to lower intake temperatures and reduce heat soak, ensuring consistent power during repeated pulls. It also features a VRSF aluminum charge pipe upgrade, which replaces the restrictive OEM plastic pipe to improve throttle response and boost delivery. Buyers can choose between a VRSF de-cat downpipe for maximum exhaust flow and performance (intended for track and off-road use) or a VRSF sports cat downpipe with a high-flow catalytic converter for increased performance while retaining emissions compliance. This kit is presented as the ideal foundation for Stage 2 remaps, offering benefits such as cooler intake air, stronger mid-range power, improved top-end pull, and enhanced reliability for tuned cars. The components are known for their excellent fitment and quality, making this a trusted choice for enthusiasts. Professional installation is recommended for this hardware package.
