All the international idi engines have roller hydraulic lifters in them. These same lifters are used in all the psd engines as well as the chevy 6.2 and 6.5 engines. There are several other completely differant engines that use the same exact lifter... So is it any good.... You betca its a good lifter if it can be used across the board sucessfully. Figure spending around $9.00 to $10.00 per lifter most anywhere. Ebay has the lowest price for a set. I have seen them for $99.00 with no shipping or handleing charge too... But not too often....
