I personally wouldn't give him any money back. I believe he got a pretty good deal, even though he got the wrong exhaust cam. The fact that he's willing to keep the cams means that he can use them in some way. Explain to him that you will be losing out because the ITR intake cam goes for around $291. If it's possible, ask him to return the cams for a refund.



You could check an online Acura parts dealer for the pricing on the cams.
