For sale is a set of 4 used ID injectors. Used them for 2 seasons. These are B series injectors but top hats can be easily switched for other applications. They were cleaned last season by ID and flow tested like new. I'd like $500 shipped or $475 picked up. I payed $775 for these injectors brand new.
