    What model year and what's the mileage? Without any videos of your ride (or seeing your vehicle in person), it's a bit difficult to diagnose. However, if this is the second time this has happened, then I would question you on the waterpump (it's bearings in particular) if the waterpump fails, it would allow the fan blade to wobble thus causing it to Shred things in the engine bay.?

    I have an E46 330i and the only performance item I have is the Signature Motoring performance CAI for about $160. The performance kit adds around 13.5HP on the dyno, sounds freaking great, and installs in under 30 minutes. Highly recommended.

    -13.5 HP increase
    -Lifetime filter
    -30 min. install time

    Aside from the power gain,? the SOUND is amazing at higher RPM but sounds normal in regular driving. I'm thinking about added high-flow exhaust next.
