These Kinugawa oil feed kits are to suit either the factory TD05HR-16G turbo, or any of the Kinugawa aftermarket performance turbochargers for the EVO 4-9 (TD05, TD06 etc). This is the oil filter housing oil supply variant, where oil is taken from the oil filter housing instead of the cylinder head. We recommend this kit instead of sourcing from the stock location for all EVOs running elevated boost levels. The filter housing offers a much stable oil supply at the required pressure. Ultimately, this line could well save your turbo! 320-01034-018
