ordered this oil cooler from summit for the hydro set up. I looked at some local auto parts stores and wasnt really impressed with the quality they carried. it looks like it should fit nicely behind the grill because its only 3/4 inch thick and has 3/8 inch barb fittings (which are the same as stock lines) I do believe I can use all the stock lines to connect as well...no additional plumbing but we'll see.
