i've had the oil relocate kit moved to my airbox location. (92 civic) it was convenient for a while until the fittings all backed out no matter if you torqued them correctly. (greddy kit)
it isnt worth the hassle of the leaks that it causes. you also lose a bit of oil pressure which is important on VTEC and iVTEC engines. throttle response is sacrificed a bit.
if you decide to go this route, make sure you get quality fittings and high pressure hoses. the greddy kit is a POS.
