Kracka Vents!!!
As some of you know, I'm a big fan of Krank Vents since I have seen many benefits in using them both from my personal use and reviews written by others. They are a great product, but a tad ridiculous at $110. Rather than suck it up and drop the cash I decided to source my own that meet all the proper specs!
Benefits I have personally experienced:
Crankcase vacuum (basically suctions the oil dipstick in)
Smoother idle
Increased MPG
Increased throttle response
and much less oil consumption (due to the piston rings sealing better)
Dyno-tests are also showing a 3whp gain on N/A S2000's and up to 20whp on turbocharged S2000's. These work the same way on all cars, N/A or FI. These should help to eliminate some minor oil seepage/leaks such as the oil cap, valve cover gasket, etc. along with preventing the dipstick from popping out under boost. Long story short, these basically prevent air from entering the crankcase from a leaky PCV valve or the breather port.
I'm running a set on my car and so far they are behaving exactly as I expected. One goes between the PCV valve and intake manifold, and the other goes between the valve cover breather port and your intake/breather filter, catch can, etc.
