S54 CSL edition

The upgraded S54 engine used in the E46 M3 CSL has a high flow carbon fiber air intake, modified valve and camshaft timing, and a retuned DME using a MAP sensor instead of the MAF sensor found in a standard M3. However, the engine is further modified in order to reduce weight – it features a lightweight exhaust manifold (made standard on late models of the normal M3) and thinner exhaust piping. Additionally, the intake and exhaust manifolds are slightly straightened to improve engine responsiveness.
