    I got genuine ones and expect them to last a long time and they weren't that expensive. The same NGK plug aftermarket wasn't any cheaper I don't think. This is on a 1.8T though.

    Look on ETKA and see if the original are NGK, Bosch etc as it will tell you the make and code on there.

    I think the iridiums are around 30k, but I personaly use copper plugs and change them avery oil change due to the low cost compared to the £35 cost of the iridiums

    There was a guy in the states who changed spark plugs on a customer's a3 after 110k miles. They were the original 11 years old parts and when he tried to get the same part number from dealer, they told him that them spark plugs are now obsolete and offered him better ones ! Wonder why they were obsolete, maybe because they last longer ? In easter Europe, me dad used to change spark plugs every 5-10 years and ONLY if the car was hard to start in the winter at -20-30 Celsius !

    Fair one fellas. When I changed mine 10k ago I knew bugger all about these cars, so took the autofactors advice and used NGK BKR6EKUB-3584. Were these the right ones?

    I use BKR6EK's in the 1.8T

    NGK recommend silly platinum plugs (PFR6Q) but the BKR6EK is the copper equivalent.

    The UB plugs have a much shorter tip than the 6EK's and i've no idea if your car should have the shorter ones or not.

    The last set of plugs i put in, i fitted at 155k and they were still in there when i changed the engine at 195k. 40k from copper plugs is a pretty long time, and they were quite past their best, but it still ran fine, even remapped.
