Use Thermal Past (NOT Anti-Seize) on the spark plug threads and Dielectric Grease on the Spark Plug boots, (not the Coil Boots). I highly recommend you change out your spark plug wires with a High Quality set (not OEM). If you don't, you will be very disappointed. Especially when you have to do this again to replace them. If you do these things, I think you will be impressed!
