This listing is for a new Genuine Holset HX30W with 6 cm2 housing. This is a great turbo for upgrades or factory replacement (on some non-Mercedes engines). Please make sure to verify compatibility before ordering. BenzForce sells turbos primarily to customizers/fabricators. If installing on a Mercedes engine, expect to have to make modifications to oil feed lines, oil feed fitting, oil drain line, flange adapters and compressor housing tubing/interconnects.

Additionally, there are manufacturer links to supporting informationTo offer the best prices we can, we ship via container ship. These turbos leave double boxed, two per box. Occasionally the freight forwarding company will unpack our order to maximize the utilization of the container. When this happens, the forwarding company in the USA will directly mail the individual turbos to us without double-boxing. It's the same turbo, they just add a lot of tape and mailing labels.
