If you have a VQ35DE engine, you may have been looking for a replacement for the broken clip on the "power valve". I have found a replacement (nissan doesnt sell the clip alone, only the whole valve assembly). I have them listed on e bay here
fixed my valve in seconds for a fraction of what they wanted for the whole assembly.
Feel free to ask me questions if you want.
