STi MAFci™ System
The Subaru STi MAFci™ System offers average gains of 21.7 hp and 20.1 ft lbs. above 4000 rpm’s. Peak gains of 36.3 Hp and 31.7 FtLbs. were also realized.  Stock the STi offers unreal acceleration numbers, but with the installation of the intake and the additional horsepower across the board this thing runs like a freight train. 

Each kit comes with a 3.5” high flow intake and cp-e™’s fuel management sub-computer, the MAF Customizer™ with a preset fuel map to safely extract the most horsepower possible for your STI. If you have other modifications, or if you simply desire the ability to alter the fuel map, cp-e™ now offers a user-programmable version of the MAF Customizer™

This limited edition intake is powder coated ripple red to match the red, stock intake manifold.  Also each heat shield is powder coated black to match the plastic under the hood.

Please click on the links for horsepower and torque graphs, and study them for your self. Please note the broad increase of horsepower over the entire RPM spectrum, not just a “peek spike” at red line. These large gains across the RPM spectrum are real increases that you can feel. cp-e™ has set out to build the best intake system possible for the STI, and we have achieved it. This is by far the best horsepower-per-dollar aftermarket improvement for the STI.
