The new coils were an exact fit for my 2001 Acura 3.2 CL. All components seemed to be very high quality and the engine ran perfectly after installation. Installation was easy, except for getting the electrical clip off on cylinder #1. The bar over the rear of the engine made it difficult to get a good grip on the release tab to pull off the clip. I removed the bolt holding the coil so I could twist it clockwise just enough to get a good grip and then it came right off.
