For those looking to increase the horsepower of their 335i to match the great factory torque delivery, Turbonetics and its high performance intercooler brand Spearco now offers bolt-on intercooler upgrades for the 2007-up 335i coupes and sedans.
BMW owners can now enjoy the benefits of increased flow and more efficient air to help dramatically lower intake air temperatures to increase power. By using a massive 6" thick W.A.V.E. Technology core, the Spearco front mount intercooler dropped charge air temperatures on average of 125 degrees on the twin turbo vehicle. In addition to lower intake air temperatures, the pressure of air exiting the intercooler compared to the pressure entering the unit was only an amazing 0.20 psi drop. The stock unit has over one pound of pressure loss/drop due to the factory unit's lack of efficiency and limited size. When the stock unit is upgraded to the Spearco you will have less heat and more power due to the ability to quickly and efficiently move the pressurized air through the intercooler assembly.
Once the initial investment is made, the result is a lifetime of free power and improved fuel economy. The intercooler reduces charge air temperature entering the engine, increasing the air density for increased power and torque, while reducing the overall thermal load on the engine and cooling system as exhaust temperatures are reduced at the same time. This results in less transfer of heat to the cooling system, and engine compartment and assists in maintaining normal temperatures on long hard power pulls. Since the intercooler is mounted in the factory location there is no need to worry about making any modifications to the vehicle. In addition to power and performance, you can anticipate an increase in fuel economy as the cooler, denser air creates a leaner air-to-fuel ratio.
Spearco's drop-in replacement intercooler upgrade features W.A.V.E. Technology bar and plate cores for increased strength and efficiency by utilizing the maximum surface area of the cores available each core is pressure tested to over 200+ psi. Hand crafted and precision welded, each Spearco assembly is fabricated to strict tolerances and every unit is pressure tested underwater to ensure a leak free intercooler assembly. The Spearco Intercooler upgrade drops in place very easily in 2-3 hours time. Combined with higher boost pressures, the Spearco 335i front mount intercooler provides a win-win combination of additional power and increased efficiency.
