FAQ
What does the "Extra Oil Clearance" designation mean?
This set uses standard journal sizing but is machined with additional internal clearance, a spec some performance engine builds call for.
What vehicles does this fit?
Infiniti G20, Nissan 200SX SE-R, NX, and Sentra SE/SE-R, all equipped with the SR20DE/DET 2.0L engine.
Is this the 17mm-wide version?
Yes, SR20 bearings were made in more than one width, and this listing is specifically the 17mm-wide set.
When should I choose extra oil clearance over the standard-clearance set?
Only when your engine builder specifies it, typically for higher oil pressure systems or specific performance clearance targets.
