That is all you need! There is just three bolts. Access is the only problem and it is doable, the stock parts kinda fall out, you'll have the cover, spring and diaphragm. When you install the BOV pick one of the bolt holes to be the top and slip the hose and retainer on before starting to bolt it in, it took me a few minutes if fenagling and a shot of WD-40 to get it on. Slipping it on was easy, getting the clamp back into place, not so much.
