The Damond Motorsports Turbo Oil Restrictor Bolt, reduces the oil feed to the factory K04 turbo, to help in preventing the common Mazdaspeed "smokey-turbo." Using proven and tested hole diamaters, the Damond Motorsports bolt allows proper oil feed to the factory K04 turbo, without over-oiling the turbo, and prevents oil seeping past the turbo seals into the exhaust. In addition 2 new OEM spec copper crush washers are included. This is a great, low-cost component, if you're looking to add a catless or more free flowing exhaust that would potentially result in more exhaust smoke. 

Also works with BNR turbochargers. 
TQ spec is 18-26lbs/ft

Performed as advertised!

Did just what I needed it to do. Catless dp and full 3” straight exhaust, my ko4 was smoking like a banshee. Oil restrictor bolt has currently solved that issue.

It has worked wonders for my smoking problem accompanied with some oil additive my car doesn’t even smoke almost at all anymore

Great bandaid

I purchased this bolt probably 6 years ago now and it took until now for my junk stock turbo to start smoking people out again. To me, that makes it a $0.42 monthly subscription to not have a smoking turbo. Well worth it. Super easy install. Probably not even worth doing the review since anyone with a K04 has already done this but its definitely a product I would recommend, especially as a temporary fix.
