It ended up costing over $100 to get the part shipped to your house, then once you have your old part out (the "core"), you email them for a return request, they email you a label to put on the box for shipping, and you ship the old part back to them. Then they refund you the "core charge" once they get the old part. It's a way for parts manufacturers to get parts so they can remanufacture them. Not sure if GM sends them back to Denso or not. Hope that helps.Thank you for the quote for the part! I've been finding 175+ for that motor
What is a core charge anyway?
