FAQ
What does the extra oil clearance spec mean?
It's a Standard-size bearing machined with roughly an extra 0.001 in. of oil clearance (thinner bearing wall), often used in higher-RPM or racing applications, while still fitting a factory, unmachined crank.
What vehicles does this fit?
The Honda S2000 (F20C/F22C engine) and the 1997-2001 Honda Prelude (H22A4 engine).
Should I use this or the standard 4B1912H-STD set?
Use this Extra Oil Clearance version for racing applications needing added clearance; use the standard set for a stock rebuild or mild street build.
Is this a rod or main bearing set?
This is a rod (connecting rod) bearing set only.
