Fourtitude has discovered a company called CarLine that produces conversion kits to add Audi's single-frame grille to the company's previous generation of cars. The CI-Look package is available for the B5 A4 and first-generation TT ( gallery).
Other companies have hopped on the single-frame grille bandwagon, as well. Hofele Design produces a tasteful single-frame conversion kit for the first generation A8 sedan ( gallery) and tuners Mattig ( gallery) and PPI Automotive Design ( gallery) also make their own kits for the first gen TT.
So don't fret if you're stuck with one of Audi's previous generation cars – you too can have the same gaping grille as the current models.
