Improve the performance of your E46 M3 with the Rogue Engineering Performance Intake Boot. Made from high quality, 4-ply silicone, it removes the turbulent ribs of the factory plastic elbow and smoothes the air intake path to the intake manifold.
The E46 M3 boot fits 2001-06 E46 M3 (US and Euro, NOT CSL). It does not fit the MZ4 Coupe or Roadster. This fits OEM intakes or aftermarket ones that use the factory, plastic intake elbow. This is NOT designed to fit aftermarket intakes that have been designed with their own elbow.
The E46 M3 intake boot includes replacement clamps, as the factory ones are not large enough to fit around the larger OD of the replacement elbow.
Intake boot intentionally left longer, to fit various aftermarket intake systems. Trim 1/4" off the smaller diameter end when using it in place of the factory boot only.
