    What are the best spark plugs for the 2.0 fsi engine? I know fsi engines are fussy on the manufacturer/model of spark plugs they have, so can anyone give me any advice? thanks

    Best plugs imho are o.e std plugs. They were chosen by audi to be the best suited plug for your engine. Bosch or ngk are most known types. Are you looking to upgrade them? The only obes ive used are denso iridium, expensive but seemed to be a good plug.

    The ones i've got in at the moment look a bit worn, so I was just wondering if there is any upgrades, and Ihave a miss fire at low rpm, and wondered if the spark plugs could be causing this.

    I've always found NGK's to offer most consistent result. As it's in the B6 forum and the first car mentioned is a 2.0FSi, I'm 'assuming' your car is a 130bhp model and manufactured some time between 2000-2005. If not then these part numbers are not right.

    OEM Part: BKUR5ET

    Iridium Part: BKR5EIX

    Iridium tipped plugs have harder tips, so in motorsport applications they last longer. I used them for about 4 years with mixed results, and have returned to the standard platinum electrode plugs as they seem to foul less in the FSi engines, especially when modified. Also NGK say they conduct better than the Iridiums which as built for endurance rather than outright smooth running.

    If these aren't the right ones, suggest you look at this website that helps you choose step by step: NGK Partfinder Catalogues
