{"product_id":"optispark-distributor-vacuum-harness","title":"Optispark Distributor Vacuum Harness","description":"It is designed for 1993-1997 B-, D-, and F-body vehicles, specifically the Camaro, Firebird, Impala SS, Fleetwood, Caprice, and Roadmaster. This part directly replaces the discontinued GM part number 12555323.\n\nThe check valve and filter are made from Viton material for enhanced durability and maintain the original micron rating.\n\nKey features of this harness include optimized vacuum flow, thanks to the precisely designed vacuum orifice, which ensures proper function without causing distributor damage.\n\nIt is important to note that this vacuum harness is not compatible with Corvettes. A separate, Corvette-specific harness is available for those applications. For installation, it is recommended to use a non-silicone-based lubricant like WD-40 or CRC when attaching the vacuum hose to the distributor cap, especially in temperatures below 85°F, to ease the process. Minor variations in components may occur due to availability.","brand":"Petris","offers":[{"title":"Default Title","offer_id":52663249699128,"sku":"OEM \/ Interchange Numbers = 12555323","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687075635.webp?v=1784325343","url":"https:\/\/store.motormia.co\/products\/optispark-distributor-vacuum-harness","provider":"MOTORMIA","version":"1.0","type":"link"}
