    Performance parts for a 07 550i

    Hey guys,

    New member here. I just picked up my 07 550i (european delivery) and looking to do some minor upgrades. I would like to find a comp. chip for a little more horsepower, and maybe upgrade the brake package. Heck, I would like to get an H&N filter but I cant even find that. Are there any performance parts for this car, or is it a) too new or b) there is just not a demand for performance parts for these cars.

    Thanks in advance, look forward to chatting with all

    Robert

    Jason,

    You beat me to it. Money spent on drivers schools may save your life one day. Best perfroance mod money can buy. My advice do schools and dont make any performance mods until you are faster than the car.

    Robert, aside from echoing the advice that Jason and Dave voiced about spending money first on your skills, then, later 'upgrading' the car (although aside from dropping a V10 into it, I don't really see what you can do), the best advice I can give you is: never, ever, put a K&N in your car.

    A) It actually causes a performance drop, and
    B) The additional dirt it allows through will cause more wear and tear.

    My race car had a K&N cone when I bought it; it now has a factory airbox and a Mahle paper filter and I have the dyno data to back up that choice.

    That's interesting Dave, I've seen many many dyno charts from several different air intake manufacturers that yield nice power gains. I however agree with you about allowing through additional dirt, paper filters are excellent at keeping the engine clean.

    First, why do so many people see "Dan" and read "Dave"? It happens all the time, not just here, BTW.

    The airboxes on fuel-injected BMWs are designed as a cold air intake, drawing air from outside of the engine compartment. On bone-stock engines, the flow restriction resides in the AFM, not the airbox. Surprisingly enough, those BMW engineers realized that their engines perform best when they get cold air and as much of it as they need.

    Now, if you swap out the AFM and bore out the intake manifold or the head, gut the cat or some sort of serious physical change to your engine, then a bigger intake might provide a gain.

    The few times I've seen the K&N cones or other "cold air induction" systems provide positive gains is on other manufacturers cars whose intakes draw warm air from the engine compartment or on models which offer various engines, but went cheap on the intake by offering only one design. (CoughFordCough)

    Why would you believe any manufacturers dyno chart for any part they sell? Its their dyno under their conditions and test methods. A certain tuner over near Fairfax Circle was known to post questionable dyno numbers. And there are countless others to include K&N.

    Sorry I guess I wasn't clear enough. If you browse bimmerforums and do some searching you'll easily find member's dyno sheets for almost any part including intakes. From all I've seen intakes usually net around 5-10 hp on the dyno. I am talking about e36/e46 models.

    Hey Guys,

    Thanks for the replies. I'm set in terms of a drivers school. I actually race formula continentals in SCCA. Been doing it for a few years now. That said, I think you are right about the K&N now that I have thought it through more. I use a K&N on my formula car, but the motor is constantly being rebuilt, so dirt isn't as much an issue. I didn't really think about it in terms of applying it to a street car.

    I guess I was just looking for some easy bolt-ons to gain a little more HP. At the end of the day, I don't plan on doing anything hard core with the new car, thats why I have the formula car!

    Thanks again guys.

    Robert

    Take it from somebody who used to sell "D i n a n" for a few years, it's just not worth it on the new cars. That's just one of the many reasons we do not sell their products anymore.

    I'll have to double ditto what all three of these gentlemen have just said.
    I have heard so many stories of these types of filters spewing oil (and thus dirt) all over the MAF and causing them to need frequent cleanings and even premature failure.

    Also, go to driving school.

    To be fair, even ITG filters can cause problems if not cleaned and recharged properly. I clean my ITG filter and make sure it's good and dry before reinstalling.
