Everything in red is to be done fella, I should include a key for my sig huh, lol, anyway not fitted but 50% there, they're from a passat but the pipe & plug fit 100% but one side has wires to be extended by 2-3 inches & the jets need some glueing or sealant to hold in place as they arent as deep as the a3 oem ones, but I'm gonna do some hunting on the audi lot to see if they have replaced these on other cars then swap to the audi version, if not then I'll fit the passat ones as not really hard to do.
Do a search on here for fan spray jets as there's a thread I'm in on which has part numbers.
