2.0 Turbo Z20LET engines come from factory with a non restricted oil feed, this oil pressure is to much for the turbo oil seals, which can cause them to fail, and make the car smoke at idle, so we recommend fitting the Oil Feed Restrictor for peace of mind & a longer turbo life.
Direct replacement oil feed banjo bolt. Designed to reduce oil pressure at the turbocharger. While remaining high enough to lubricate the turbo the reduction in pressure does not overpower the seals.
