i bought this from atp turbo and don't need it so it is for sale. its brand new in the box. its the oil inlet fitting with built in restrictor that is needed when you upgrade to a bb turbo.
price- atp sells it for $20 shipped so save yourself 5 bucks and buy it from me for $15 shipped.
here is the link to it on atp's website.
