    • Evolve Automotive E85 Z4M CSL style S54 carbon airbox development with Alpha N tune pictures, video, and dynos

      The CSL airbox. A thing of beauty both in looks and sound for the S54 engine. The E85 Z4M never received a CSL version which was solely applied to the E46 M3. That did not deter demand from Z4M owners for a CSL airbox application and Evolve Automotive is accommodating this demand. Completely stock the Z4M on Evolve Automotive's Dyno Dynamics put down a respectable 269 horsepower to the rear wheels.

      With the CSL style airbox and Evolve Alpha-N tune? 290.8 wheel horsepower. Very solid naturally aspirated gains of just over 30 horsepower at the wheels on a fairly conservative dyno. Keep in mind a tune is necessary to maximize the gains with the airbox just as BMW had to do with the E46 M3 CSL.

      Check out the dynographs, pictures, and video below. Z4M owners, enjoy.

        That sound is amazing. I love this car, and love the engine more. I think it's the best engine BMW M has ever made all things considered... A few years back, 30+ NA rwhp was unheard of on this engine - this is good stuff. I want.

        Add SuperSprint headers and a mid-pipe and its a dream to drive. Had an M3 with this setup with full SS from the header back...i loved everything about it. Power everywhere, powerband smooth like a Porsche..almost considered buying the M3 over a 911 Click here to enlarge
