Oil Lines: the plumbing that keeps oil where the engine needs it

An oil line carries pressurized oil from the block to where it does work - a turbocharger center section, an oil cooler, a remote filter, or back to the sump as a return. It has to hold up to heat, pressure and vibration without weeping or splitting. When a factory rubber line goes hard and cracks, or you add a turbo that needs its own feed and drain, the right oil lines are what keep that oil moving and off the exhaust. Braided and reinforced kits swap the failure-prone factory hose for something that seals at the fittings and routes cleanly around the manifold.

Turbo feed lines meter oil into the bearing; return (drain) lines let it fall back under gravity, which is why return lines run larger and need a clean downhill path. Get either wrong and you cook a turbo.

What ThreePiece stocks in oil lines

There are 18 oil line products on this page, spanning 7 brands: Torque Solution, Mishimoto, Fleece Performance, Bikers Choice, TwinPower, Gates and Wehrli. Current pricing runs from $38 to $556 for what is in stock - a range, not a promise, so check each listing. The spread reflects the split between single hoses and complete multi-piece kits.

Coverage skews toward turbo diesels and performance builds. Fitment data on this page names makes including Harley-Davidson, BMW, Dodge, Ford, Mazda, Chevrolet and Cummins, over model years from 1966 to 2022. Concrete examples: the Mishimoto RX8 oil line kit, the Mishimoto F8X M3/M4 nylon braided hose kit, the Wehrli Cummins high-mount turbo swap kit, and Ford diesel and gas turbo kits from Gates including the 6.4L Super Duty kit and the 3.5L F-Series kit.

How to choose the right oil line

Start with the job. If you are replacing a specific factory turbo line, a vehicle-specific kit like the Gates Ford kits is the least-fuss path - it comes shaped and fitted for that engine. If you are building a turbo setup, a braided AN kit such as the Torque Solution EJ -10AN turbo oil return line kit gives you sizing and routing control but assumes you know your fittings.

  • Direct-fit vehicle kits - fastest install, no AN math, matched to one engine.
  • Braided AN kits - flexible routing and larger returns for turbo swaps, but you confirm hose ends and adapters.
  • Budget vs. build - the low end covers simple single hoses; the higher figures are complete turbo kits.

What else you need

AN-style oil lines almost always need matching fittings and adapters to land against the block and turbo. If you are servicing the oiling system while you are in there, look at oil filters, and if a turbo swap has you deep in the engine, browse gasket kits too. Everything here lives under Engine Components.

Fitment help and ordering

Match the kit to your exact year, make and engine before you buy - turbo lines are engine-specific. Not sure? Call for fitment help at 813-535-5801 or reach us through contact us. Every order ships with free shipping, and Affirm financing is available on larger kits.
