KPALAG PCV Valve Tubing Hose for GM 1.4L Cruze/Sonic/Trax/Encore 2011-2020 Direct-Fit with Bypass Valves

KPALAG PCV valve tubing with integrated bypass valves is a direct-replacement crankcase ventilation hose engineered to restore proper crankcase pressure control on select 1.4L GM vehicles.

If your Chevrolet Cruze, Sonic, Trax or Buick Encore with a 1.4L engine is exhibiting oil smell in the cabin, slow throttle response, or service reminders related to the PCV system, a worn or leaking PCV hose is often the root cause. This KPALAG assembly replaces OEM numbers 25193343, 55568267 and 46829 and reproduces the original routing, valve locations and oil-resistant materials to help return the engine breathing system to factory specification.

How does this PCV tubing restore proper crankcase ventilation?

The assembly channels blow-by gases from the crankcase back into the intake while using built-in bypass valves to regulate flow under different engine loads. That stops excessive crankcase pressure and reduces oil leaks and seal stress without modifying engine hardware.

• Direct-fit replacement for the original routing and connections
• Integrated bypass valves replicate OEM flow control
• Oil-resistant materials resist swelling and deterioration

Which vehicles and part numbers is this compatible with?

This KPALAG hose is manufactured for GM 1.4L platforms and matches the factory specifications used on several compact models. Always verify your vehicle’s OEM part number before ordering to ensure fit.

• Fits Chevrolet Cruze (2011–2016) and Cruze Limited (2016) 1.4L
• Fits Chevrolet Sonic (2012–2019) and Trax (2013–2020) 1.4L
• Fits Buick Encore (2013–2019) 1.4L; replaces 25193343, 55568267, 46829

Is installation difficult and what tools are needed?

Installation is designed to be straightforward: the hose pushes into the factory ports and secures with existing clamps or clips. A basic set of pliers and a flat screwdriver are usually sufficient, though professional installation is recommended if you’re not comfortable working under the hood.

• Push-fit connections; clamps or clips replaceable without special tools
• Typical install time: 15–45 minutes depending on access
• Contact a qualified technician if routing or clips are corroded or stuck

What are the material and durability characteristics?

The hose is molded from oil-resistant polymer selected to withstand exposure to crankcase vapors, heat cycles and engine oil. Its durability aims to match or exceed OEM service life so you avoid premature softening, cracking or leaks that can lead to engine bay contamination.

• Oil- and heat-resistant elastomer construction
• Factory-style valves to preserve flow characteristics
• Manufactured to OEM dimensions for leak-free sealing

Who this is for: This KPALAG PCV valve tubing is aimed at owners and mechanics servicing 1.4L GM compact cars and crossovers who need a reliable, direct-fit replacement for a failed or aging PCV hose. It’s appropriate for DIYers familiar with basic engine maintenance as well as professional shops replacing OEM part numbers 25193343, 55568267 or 46829. If your vehicle shows symptoms of a compromised crankcase ventilation system—oil smell inside the cabin, oil leaks around seals, or engine performance irregularities—this hose restores correct ventilation pathing and valve function with minimal fuss.
