What's the word on this intake? a GruppeM ripoff?
<<After careful research and development, the RD Sport Sport Sound Intake Silencer is now available. The CAD designed CF housing provides a Ram-Air effect for the specially designed filter while keeping out the engine's heat.
The filter is made from Polyester material that in testing has 93.1% filtration rate vs. 40-70% filtration rate of cotton gauze. (The tests based on 100 micron particles). The polyester material flows more air than the cotton gauze - 6.3CFM per square inch of material vs. 6.04 CFM for cotton gauze. Another advantage of the polyester is that it never needs oiling. So now there is no chance of damaging expensive MAF sensors by using too much oil.
Fits E46 with M54 3.0L engines, 330i all styles.
