Selling my car.. I am posting things as they come off..
I believe they are originals.. I never had an issue. infact I have 2 sets of them. The other set have a couple ears snapped off them.
I never had them Dyno tested,but you could really notice the difference over stock when you put them on.
I had a buddy helping me work on my car,and he kept putting his hand on them,and snapping them off at the mount. So he bought me a whole new set.
