Oil Line Kits, Turbo Feed, Return and Cooler Lines for LS, WRX, EVO

Turbo Oil Feed and Return Lines

Turbo oil feed and return lines must match the turbo, engine oil source, drain location, fitting style, and heat exposure. A well planned kit supports dependable lubrication and clean routing.

Correct routing for turbochargers

Turbo oil feed and return lines must match the turbo, engine oil source, drain location, fitting style, and heat exposure. A well planned kit supports dependable lubrication and clean routing.

Oil Cooler Line Kits

Oil cooler lines connect the engine, cooler, thermostat, and fittings in a controlled circuit. Confirm hose length, thread type, pressure rating, and cooler location before ordering.

Cooling circuit planning

Oil cooler lines connect the engine, cooler, thermostat, and fittings in a controlled circuit. Confirm hose length, thread type, pressure rating, and cooler location before ordering.

Braided Hose and AN Fittings

Braided hose and AN fittings are useful for custom plumbing, but they must be matched to the fluid, pressure, temperature, and fitting seat style.

Common Questions

What is a turbo oil feed line?

A turbo oil feed line routes pressurized engine oil to the turbocharger bearing section using the correct fittings and hose type.

What is an oil return line?

An oil return line drains oil from the turbocharger back to the engine or oil pan using a properly sized, unrestricted path.

Are oil line kits vehicle specific?

Some are direct fit while others are universal. Confirm engine, turbo, fitting size, hose length, and mounting details.

Do I need an oil restrictor?

Some turbochargers require a restrictor based on bearing type and oil pressure. Follow the turbocharger manufacturer guidance.

Can braided hose be used near headers?

It can be used when properly routed and protected, but heat clearance and shielding are critical.

How do I select AN hose size?

Select hose size based on fluid volume, pressure, fitting compatibility, and the kit or turbo manufacturer recommendation.

Are cooler line kits only for engine oil?

No. The collection also includes transmission cooler and diesel service line solutions where listed.

Do oil lines need sealant?

Use only the sealing method specified for the fitting type. Incorrect sealant can contaminate the oil system.

Can I reuse old oil fittings?

Inspect threads and sealing surfaces carefully. Replace damaged or unknown fittings to avoid leaks.

How do I confirm fitment?

Use the vehicle filters and review product notes for exact engine, turbocharger, transmission, and model year details.
