like the title states I have 4 Bosch 1600's low impediance I bought from a guy on here for my turbo build but dont need them any more because I have 450's I'm using. Before I got them from the guy they were cleaned and flow tested and work perfectly. I would like to see whats out there that you'd want to trade for. If any one has a good wide band sensor and gauge I would trade for that. Let me know what you have. I have an lsv turbo so if you have any parts for it let me know as well ex. TB or IM? text 4173177097 for pics or im me
