I need a bosch 3737 o2 sensor but i can only find them on ebay... dealerships have them... (liek vw and volvo use them in there cars as oem parts) but i need the part number because they cant look up bosch 3737 they need like vw ***-***-*** or something... soo... does anyone know the oem part number or anything cause i need the 5 wire o2 with the 3737 head so i can tune my car...

Thanks
