Customer Review: (see review/s)
  • The product was good overall, the price could not be beat anywhere and I had put in a great deal of research on this product. The product did not ship in a box, it was just drop shipped @ my front door, which was odd. Moreover, when I purchased product I was not told that it did not ship with gaskets which caused a bit of a slow down on install. My mechanic did experience some problems installing product. It was a tight fit with NO room for error - professional install recommended
