    I would go for a nice set of springs that don't lower the car and again of he has money to spend a remap but that's about it really I think!

    You can't fit a supercharger and carbon CSL manifold as most charger's have their own manifolds, well I have never seen a CSL manifold and supercharger which is not to say they don't exist but is unlikely i would have thought.

    Regards the OP, the E46 M3 induction system is one of the best factory setups out there and can not be bettered unlike other restrictive models (like E36), even by the likes of Gruppe-M. K&N will most definately lose you power as their heatshields are totally mickey mouse and not completely sealed. The E46 intake works on a semi-pressurised pulse system so as soon as you take the airbox away you lose the pressure and pulse tuning that BMW probably spent millions on developing. Its well proven that the OEM system is best I believe, at most get a BMC panel filter. For power if he already has Milltek cats and back box i would definately get the Evolve remap, not a single person has anything negative to say about it and all say it has increased power/throttle response and got rid of the kangarooing that some/most E46 M3's have from cold start. Check out the reviews on cutters.

    Other than that if he wants to go faster, lose some weight! nice light recaro's will save him abotu 30-40KG alone.

    spot on!
    A well tuned factory NA engine won't require any further mods. From my experience any open air cone filters will bog down the performance of NA engines no matter what heatsheild or how many air feeds it has.

    Personnaly I would change the panel filter for a K&N replacement and then lighten the car. The milltek exhaust system is already a top quality and well proven product.

    hello mate,

    your bit about open filter, I agree and disagree. Agreed that one without heatshield or rubbish shield (tried this too) will bog down once engine is warmed up. Although, this wouldn't matter on somewhere like a track where there is open air and the car is moving most of the time as the on coming cold air will constantly be pushing the hot air to the back of the engine and out of the nooks and cranny's. on a road car in traffic its a totally different story.

    I have actually got my external temps sensor from the brake duct and put it in my intake enclosure, (I have a pretty well shielded K&N cone) and the temps do stay low. instanding traffic they rise but then i put this sensor in the OEM air box and they also rose, as soon as you start to move it starts to drop again until its steady. Granted, with the OEM airbox they drop very rapidly, more so than with a shielded cone but the added throttle response/pickup and BHP the cone gives over the OEM box makes up for this. Mind you this is on a E36 Evo which has a restrictive box compared to the E46 M3. I also have a very large (3+")airfeed going into the enclosure from my brake duct and have channelled air to it from the kidney grille too so when moving the temps drop quickly and stay low.

    It all depends on the design and materials used to make the heatshield, I have made a lid for mine too so as much of the hot air is blocked off as possible.

    We map a good number of them.. as said there qucik enought but the map will really help with low speed driving and will gain on mid range responce.. We have dyno'ed them with a cat back and a map see over 360hp...

    mmm, have heard that sport cats and remap make a good difference from standard power.

    Do you guys map the vanos profiles as well?

    Best mod for an E46 M3 is the 4.10 diff swap. Standard gearing is far too long.
