My car was idling very rough, and popped a code for air intake leak. I had replaced only the pcv valve the first time, and it worked for about a month. When the rough idle came back, I ordered this valve cover. I got the part 3 days later, and installed it. It was more work getting the engine cover out of the way that it was to change the valve cover. This part did the trick for me, and the service from DAP is fast. I'll be ordering more parts from them in the future. Thanks again guys!!
