Would there be any intrest with a Oil Filter Cover with a 3/8 socket end built in ? <p>would be a direct swap for your plastic one and would be able with a 3/8 wrench just spin it right out so you wont have to worry about a strap wrench or what ever. <p><br>Just a thought off the top of my sleepy head. <p>I am ehhh on plastic but I would bet volvo made this plastic for a reason but I cant see why a metal one wouldnt work since the orignal ones 850 and older have all been metal. <p>So thoughts , ideas , concerns ? <p>And should be cheap also thinking aluminum for this $50 each max ?
