Hey any of you guys familiar with any differences between the breather box between a 1995 gsr and a 1995 ls? Externally both boxes look the same, but I'm not too sure about the internals. I live in California if that makes any difference.

I am fully aware that they both have different part numbers: gsr (11851-P72-000) and ls (11850-PR3-000).

Any input would appreciate. Thank you.

 

Theres no diffrence the PCV box is the same. Wont affect your smog if thats what your worried about.

 

The p72 and pr3 look like ecu types to me. Just make sure they are compatible.
