Hyundai conducted minor tweaks to the ‘GK’ model in 2005, for the outgoing named 2006. The vehicle incorporated reworked sleeker blackened headlights, redesigned rear tail lights, a different range of alloy wheel designs, colored stitching on leather seats (half leather seats available for the 1.6 range). A popular modification, as promoted on www.newtiburon.com, saw owners of the 2003 vehicle removing the air-filter resonator box. The resonator box was located directly in front of the front left hand side wheel, behind the fender. This allowed for a greater airflow to the air filter, gaining a minimal increase of (BHP). Hyundai, seeking cost cuts, adopted this modification for 2004+ models.
The 2007 model has seen minor changes in interior & exterior design. Most notably the previously amber gauge and button lighting has been changed to blue and white, similar to what can be found in the line. Exterior changes include muted side scalloping, new headlights and grille design and revised tail lights.
