The Complete Engine Breathing and Cooling Kit includes the SILA Concepts Boost Pressure Silicone Hose, SILA Concepts Exhaust Manifold Cooling Silicone Hose, Hose Clamps and the BMC High Performance Air Filter for the Alfa Romeo 4C.

Once you begin increasing the power on your Alfa 4C the stock rubber boost pressure and exhaust manifold cooling hoses can begin to breakdown and start to leak. Upgrade the unreliable rubber hoses to these High Quality Silicone Hoses designed to handle higher pressures and temperature.

Each hose is molded to fit precisely and are designed to handle substantially more power. They are High Quality direct replacements for the factory rubber hoses.

The kit also includes a BMC High Performance replacement air filter. We do custom fabrication and design on premises and when evaluating the factory intake system on the 4c we felt that a high quality, high flow filter like BMC is a better alternative to a replacement intake unless intake noise is specifically what you are looking for. There is simply no way to beat the factory ducting on the vehicle if you are strictly focused on getting the best performance. While this BMC Filter will give you a throatier sound, it is not as loud as an aftermarket intake that others offer. If you are looking for the best combination of filtration, performance and function this drop in filter cartridge cannot be beat.

Each BMC Filter is hand oiled with a high quality oil that is exclusive to BMC so there is no issues with any sensors being fouled over time like with other pre oiled air filters.

BMC Filters offer a wide filtering area allowing higher air flow passage along with greater retention and screening. This gives you better mileage, fuel efficiency and guarantees containment of impurities as small as 7 microns (compared to OEM's 10 micron). BMC Air Filters are reusable and have a general life-span equal to that of your vehicle unlike OEM filters. BMC Filters are the top in the industry and are used around the world in many different race and high performance cars. When it's time to upgrade the performance of your Alfa 4C, it's only fitting that you give it the very best.
