    dont really think it matters cause its not gonna improve your performance by much, dont hold me to that but im sure they dont

    wont make any diffrence

    the cheaper ones wont last as long as the good ones

    iridium ones last a bout 30k miles

    Yeah dont waste money buying 'performance' spark plug as they wont be any different to standard ones.

    way back in the day I tried splitfire plugs on my mk1 xr2 and they were rubish, then put in bosch super 4 plugs and it was noticeably smoother and pulled better, so I've always used them.

    Your problem could be elsewhere, try putting a cleaning fluid in your tank & replacing the plugs
