    Hi,

    I'm changing the sparks on my BMW 318iSE E46 (August 2001 model) and I bought some new Bosch spark plugs in consort. The odd thing is...they have four pins each and I have never seen them before. My old plugs are NGK BKR6EK and they only have two pins each. I've tried ringing consort to check this out but I cant get through. Do i have the right sparks? Are they simply an upgrade?

    Thanks in advance

    spark plugs for 318 M43/ N42 are

    BOSCH FGR7DQP or NGK BKR6EQUP
    both have 4 pins accoriding to google search
    perhaps incorect plugs previously fitted.
    i have a M43 engine and it has 2 pin spark plug

    make sure they are the right length anyway - ie they screw in the same amount

    these 4 pin ones are High power spark plugs - better quality

    http://www.bmwtradeparts.co.uk/PDF/Why/21.pdf
    Function in detail
    – For normal driving, the spark plug must withstand voltage discharges from 20 – 30 kV, 55 times per second; in "stop and go" traffic, it
    must resist wear-inducing load changes; and in cold starts, it must withstand soot deposits.
    – To reduce spark erosion and to guarantee a reliable ignition, Genuine BMW High Power Spark Plugs use highly erosion-resistant
    materials like iridium or platinum in conjunction with ground electrodes.
    – The spark plugs’ heat range is an index of its capacity to absorb and dissipate thermal energy.
    – The characteristics of each BMW engine with regard to load, sealing, engine speed, cooling and fuel require a spark plug exactly matched
    to these requirements. Every engine variant has its own specification of Genuine BMW High Power Spark Plug to guarantee high
    efficiency.
    – The insulator in which the centre electrode is located determines its heat conductivity and prevents uncontrolled arcing.
    – Through semi-slide spark technology, the ignition spark always occurs over the insulator tip every time to clear away any possible
    deposits. This achieves optimal soot deposit prevention.
