anyhow, with the chromies, you can run four breathers... one of the OEM valve covers and breather setups costs $100, right? and you can only breathe as much as the holes in the cyl head will allow. I bought four chromies w/ gromets for right ~$40... four times the holes in the head = four times the flow. roughly

Four chromies go in four valve covers how is this four times the holes in the head. If you run two of these covers you are breathing through the same amount of holes in the head as four chromies. The inlet on these breathers is much larger than four chromies. You also dont end up with the oily residue all over. Four chromies are alot cheaper, no arguments there and probably breath about the same. I guess this is a mod for people that care more about astetics, looking stock, and dont like the oily residue all over the engine.
