No idea. All I know is I needed one for my volvo last year and the dealer wanted $3500. Got one from them $520 shipped. Still making full boost with it so far
jm is reliable. i bought mine there a year ago, and so far all is good. im getting 39 psi boost loaded with 70k lbs
I don't see where it can go wrong. You get the same 1 yr parts warranty, no core charge and it's less expensive. Mine looks and operates just as well as OEM. Only difference is it doesn't have the $3k Volvo name stamped in the side of it.
