{"type":"firestarter.listing","listing":{"id":"lst_FOLQjNBM","product_name":"BFI Limited Edition GS4 Alcantara (VW/Audi Manual) - Launch Edition","category":"Shift Knobs","description":"We're excited to finally offer our Limited Edition GS4 to those of you who may have missed out at L'OE Show this year!\nThe GS4 is the next evolution of our manual shift knob line. The upholstered cousin to our GS3 shift knob, an ergonomic design inspired by Porsche. With the spherical portion offset forward from the base, the GS4 gives a natural feel in the hand with each shift more crisp than the last.\nUnlike our standard black crest coin, each Launch Edition GS4 comes with it's chrome coin counterpart - the machined finish is paired with our chrome crest coin and the black anodized finish receives our popular black chrome crest coin. The GS4 shift coins blend perfectly into the precision-machined ring. In the light of day, these crest coins give a unique appearance from every angle. You won't see many of these at your local cars and coffee, so let your interior stand out from the crowd.\nMade from machined 6061 billet aluminum, and carefully hand wrapped in black Air Leather or Alcantara, these hand made knobs are distinctive but not to over the top for any European interior. We've gone to great lengths to make sure each knob is the best it can possibly be.  \nWe only made 100 of these Launch Edition shift knobs, currently only available for VW/Audi & Porsche 991/981+ manual applications. Each limited edition GS4 comes with a numbered limited edition card, and mini logo coins inserted on either side of the base. ","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/GS4SU-LE_final.jpg?v=1758030460","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/GS4U-LE_final_b27bf538-0a90-4959-8bec-c0628d24d39f.jpg?v=1758030460","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/GS4U_MK7_GTI_installed_pass_view_19a3f041-be9b-41e2-8e75-feb5af7bedfd.jpg?v=1757702693","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/GS4SU_MK7_GTI_installed_pass_side_close_zoomed_b72ba604-ede6-43ab-bc13-4b7912078b61.jpg?v=1757702693","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/GS4U_MK7_GTI_installed.jpg?v=1757702693","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/GS4SU_MK7_GTI_installed_pass_side_close_b48f1c19-67bf-4b90-91d5-f18a03a88f50.jpg?v=1757702693"],"price":289.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:25.286Z"},"share_url":"https://firestarter.network/l/lst_FOLQjNBM","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
