Hoses for your vehicle - Quality Assured Collection

What This Category Covers

The Hoses category covers flexible plumbing used to move coolant, fuel, air, vacuum signal, and crankcase gases around the engine bay. Coverage spans OE-style rubber replacement hose through silicone and PTFE upgrades built for boosted, high-temperature, and race applications.

Categories Included

Silicone radiator and coolant hose kits, braided and PTFE fuel hose, vacuum and boost hose, heater hose, and turbo inlet and outlet hose. Material options include reinforced silicone, EPDM rubber, and stainless-braided PTFE.

Silicone Coolant Hose Kits

Silicone radiator hose kits replace factory rubber hose with multi-ply reinforced silicone that resists heat cycling, cracking, and collapse under vacuum. Kits are commonly sold as full engine bay sets matched to a specific chassis and engine code.

Popular Silicone Hose Applications

Mishimoto and HPS Performance silicone hose kits cover Honda K-series and Civic Type R platforms, Subaru WRX and STI, Ford Mustang GT and EcoBoost, and Nissan 350Z and 370Z applications.

Braided and PTFE Fuel Hose

Braided fuel hose and PTFE-lined hose handle modern ethanol-blended and racing fuels without the swelling and breakdown common to standard rubber fuel line. PTFE hose is the preferred choice for E85 and methanol builds because of its chemical resistance.

Popular Fuel Hose Applications

Fragola and Earls braided fuel hose pairs with AN fittings for custom fuel system builds, while DeatschWerks and Aeromotive PTFE hose kits are common upgrades on flex-fuel and turbocharged applications.

Vacuum and Boost Hose

Vacuum hose routes signal to boost controllers, wastegates, and PCV systems, while boost hose and turbo inlet piping handle pressurized charge air between the turbo, intercooler, and throttle body. Silicone boost hose resists the heat and pressure spikes common on boosted engines.

Choosing Vacuum and Boost Hose

Match inside diameter to the fitting or nipple size on the boost controller, wastegate, or turbo piping. Reinforced silicone is preferred over standard vacuum hose on any application running elevated boost pressure.

Heater Hose and Coolant Routing

Heater hose routes coolant to the cabin heater core and is often overlooked during a cooling system refresh. Upgrading heater hose alongside radiator hose prevents a weak factory rubber section from becoming the next point of failure.

Turbo Inlet and Outlet Hose

Turbo inlet hose connects the air filter or intake pipe to the turbocharger, and outlet hose or couplers connect the turbo discharge to the intercooler piping. These sections see high heat and vibration and are common failure points when left on aging factory rubber.

How to Choose the Correct Hose

• Confirm the exact engine code and chassis, not just the vehicle year, make, and model
• Match inside diameter to the fitting, nipple, or pipe the hose connects to
• Choose silicone or PTFE over standard rubber for boosted, high-heat, or E85 applications
• Confirm hose length and routing clear the chassis, engine mounts, and accessories
• Match fuel hose chemical compatibility to your fuel type, gasoline, E85, or methanol
• Verify boost hose pressure rating matches your target boost level
• Check whether the kit includes clamps or if clamps must be ordered separately
• Inspect factory hose fittings and necks for damage before installing new hose
• Torque hose clamps to spec, overtightening can cut or deform silicone hose
• Budget for a full cooling or fuel system refresh when one hose section is failing

Common Questions

What is the benefit of silicone hose over rubber?

Silicone hose resists heat, ozone, and vacuum collapse far better than standard rubber, and it holds up longer under the heat cycling common on modified and boosted engines. Rubber hose is more prone to cracking and swelling over time.

Do I need PTFE fuel hose for E85?

Yes, in most cases. E85 and other ethanol-blended fuels degrade standard rubber fuel hose over time, while PTFE-lined hose resists this breakdown and is the standard choice for flex-fuel builds.

How do I size a boost or vacuum hose?

Match the hose inside diameter to the fitting, nipple, or port it connects to. Undersized hose restricts flow and signal, while oversized hose will not seal properly on the fitting.

Can I mix silicone hose kit brands on one car?

Yes, silicone hose is generally universal by diameter and can be mixed across brands, though a matched kit from one brand often provides cleaner factory-style routing and consistent wall thickness.

Do silicone hose kits include clamps?

It depends on the kit. Many full hose kits include matched clamps, but some hose-only kits require clamps to be purchased separately. Check the product listing before ordering.

How often should heater hose be replaced?

Heater hose should be inspected during any cooling system service and replaced if cracked, soft, or swollen. It is a common weak point that gets skipped during a radiator hose upgrade.

What hose should I use for a turbo inlet?

Turbo inlet hose should be reinforced silicone or a purpose-built turbo inlet hose rated for the heat and vibration at the compressor inlet. Standard rubber intake hose is not rated for this application.

Is braided hose better than silicone for fuel lines?

Braided and PTFE hose is generally preferred for fuel applications because of chemical resistance to modern fuels, while silicone is the standard choice for coolant, vacuum, and boost applications.

Can I run higher boost hose on a stock turbo car?

Yes, upgrading to a reinforced silicone boost hose is a safe and common upgrade even on stock boost levels, and it adds a margin of safety if boost is increased later.

What causes a hose to fail under boost?

Heat cycling, age, and pressure spikes cause rubber hose to crack, soften, or blow off the fitting. Reinforced silicone hose and properly torqued clamps reduce the risk of a boost hose failure.
