When I bought my 2005 350Z it came with this questionable intake on it. I have replaced it with a stock airbox and just want to sell this for whatever I can get. It looks like a knockoff HKS filter and says R-1 Racing Sports, a name generic enough to bring in nothing relevant in a Google search.

I'm thinking $40 on ebay...

 

That is a R-1 Racing Sports.

 

lol

 

So the name is there... and you already thinking of 40$ ...you just answered your own question yo.
