Hey guys I am new to the forums and have a few questions. I am going to change my valve cover gasket and also want to change the spark plug tube seals. I have the gasket already but for the tube seals I was wondering if anyone has used the Fel-Pro ES72481 Seals and if they fit? It says theyre compatible with my 2004 350z but want to make sure if anyone has used them on their vq engine! If anyone could help me that would be great thanks!
