    a decent air filter with heat shield and a BBTB (alpina527 can do you one i think) are recommended along with a cat back exhaust, make sure the exhaust is for a 318iS as the exhausts are specific to them
    i would leave the exhaust manifold alone, its a 4 branch already and it flows pretty well
    past that i wouldnt so much else, you could try uprated plug leads
    the M44 engines were pretty well tuned from the factory unless you want to throw money at it then youre not going to see much more power out of it

    They are mate yeh but if you want more power just do the m52 swap with a m50 manifold and the same mods disco has said also apply to the m52

    this is recommended
    however i have seen this recommendation alot on here and to be honest not everyone can afford to do this conversion
    its not the cost of the conversion itself more the stupid insurance quotes that go with it
    not everyone can afford it
    when i put the M52 into the 318iS i kept getting people saying why didnt you fit a M3 engine blah blah, S50/52s are expensive and the resulting insurance would have crippled me
    sorry for going a bit ranty, but seeing this all the time is starting to irk me a wee bit
    this isnt a dig at you niall, i do say this myself but only really in the case where people want to fit M52 2.0 6 cylinders, as good an engine it is i think its actually worth the extra insurance costs for the extra power and economy that goes with it
    rant over

    tut tut
    to be honest i would probably do that too...if I knew i would get away with it
    it will only become a problem if you have an accident and then the questions start getting asked
    the other problem is if the police stop you and check under the bonnet, this rarely happens, well its happened to me once only, its not really a risk worth taking especially if you get a ctstable that knows what they are on about

Lmao when he said it needs to get took away to see what caused it Matthew said no don't I crashed because I'm used to modern cars with modern breaks not old bangers haha

    Dont forget, a lightened flywheel can reduce parasytic load on the engine and free up a bit of power, it lets the engine rev cleanly.

    The M44 head could also be gas flowed for a mild improvement.

    Air filter selection is important to, i found the ITG best after R/R sessions.
