They aren't just face plates, they are complete units, and are accurate. The tacho is the turbo version, and isn't 100% on an NA but does work. The speedo is in KMs, so you'll have to do the mental calculations yourself. 60MPH is around 100KM/H. 100MPH is around 160KM/H etc. etc.^^ I like that look to. Do both work with the correct readings ie. mph - kph?
If its not broke dont fix it
Which ones did you go with? I ordered apexi boost and egt el2 gauges today along with the control unit. I spoke with the sales person and asked him if there were any gauges that match the mkiv interior. He said the ones that did were discontinued and no other gauges on the market match our interiors at the moment. I looked on several websites and decided to go with the el2 gauges since they have got some good reviews from some veteran members on here, and they look the best in their price range. I would have gone with defis but decided not to due to the price. I should be getting them in 2 weeks, so i will keep you guys updated on how they work.Thanks everyone, I just bought Défi gauges, they are the nicest ones I found..
