Gxencks LS Coolant Bypass Hose Kit — Aluminum Steam Port Assembly for GM LS Engines

Gxencks LS Coolant Steam Port Bypass Hose Kit is a lightweight aluminum bypass plumbing kit designed to route coolant steam ports on all GM LS-series engines.

This complete kit replaces factory steam port plumbing with a durable aluminum assembly tailored for LS engines — including LS1, LS6, LSX, LQ4 and other common GM variants. It simplifies steam-cooling plumbing, reduces failure points compared with brittle factory pieces, and provides a clean, serviceable layout under the throttle body area. The kit ships as a set intended for straightforward installation and works with most standard LS intakes (FAST 102 intake manifolds excluded).

What does this bypass hose kit actually include and fit?

The Gxencks kit centers on an aluminum steam port bypass assembly sized for GM LS family engines. It is engineered to replace the OEM plastic or rubber steam plumbing that connects the throttle body and intake steam ports.

• Aluminum bypass tube and mounting fittings sized for LS-series ports.
• Compatibility across LS variants: LS1, LS6, LSX, LQ4, LQ9, LM4, LM7 and others.
• Excludes compatibility notes: FAST 102 intake manifold applications not covered.
• Hardware for straightforward attachment to existing throttle-body locations.

How simple is installation and what tools are needed?

Installation is designed to be simple and approachable for anyone comfortable with basic engine-bay work. Most users can install the kit with standard hand tools in an afternoon without specialized equipment.

• Basic hand tools: sockets, ratchet, screwdrivers and pliers.
• No engine modifications required for compatible intake manifolds.
• Step-by-step fitting typically involves removing the old plumbing and securing the aluminum assembly in place.
• Searchable video guides are available online for visual instruction.

Why choose an aluminum bypass over factory plastic or rubber parts?

Aluminum offers greater durability and heat resistance than many factory plastic or rubber steam hoses, helping reduce leaks, deformation, and premature failures. Its rigid construction also keeps a tidy under-throttle-body routing that is easier to inspect and service.

• Improved longevity compared with original plastic/rubber components.
• Better heat tolerance around throttle-body and intake heat sources.
• Simplified service access and cleaner engine-bay appearance.
• Lightweight construction maintains overall engine-weight balance.

Will this affect engine performance or require tuning?

The bypass kit is a plumbing replacement only and does not change engine tuning or internal performance characteristics. It maintains factory coolant steam routing function without altering thermodynamics or ECU parameters.

• No ECU or fuel/timing tuning necessary after installation.
• Intended solely for coolant steam port routing and leak prevention.
• Compatible with stock and most aftermarket intakes when fitment is confirmed.
• Check intake manifold compatibility before purchase (FAST 102 not supported).

Who is this for: The Gxencks LS Coolant Steam Port Bypass Hose Kit is aimed at do-it-yourselfers, weekend builders, and professional mechanics who want a more durable, serviceable alternative to OEM steam plumbing on GM LS engines. It’s suited for restoration projects, performance builds that retain OEM coolant routing, and anyone replacing aged plastic or rubber steam components. If you run an LS-series engine and want a tidy, reliable steam-port solution without tuning changes, this kit is a practical upgrade — just verify intake compatibility before ordering.
