Nissan Pulsar GTIR - REAR PLENUM INTAKE VACUUM HOSE KIT

REAR PLENUM INTAKE VACUUM HOSE KIT – 6 PIECE

Let’s be honest — your GTI-R’s rear plenum hoses are OLD.

The factory rubber vacuum hoses hidden behind the intake plenum are now decades old. Most are hard, brittle, cracked, and only one heat cycle away from causing massive vacuum leaks, unstable idle, and boost issues.

Finding replacements is frustrating — and factory parts are either unavailable or overpriced. That’s exactly why this kit exists.

THE SOLUTION

This AlienSpeed rear plenum intake vacuum hose kit replaces those hard-to-find factory rubber pipes with modern silicone hoses designed to handle heat, age, and engine bay abuse.

Built from 3-layer silicone hose, this kit is far stronger and more durable than the original rubber, giving you long-term reliability and peace of mind.

FEATURES & BENEFITS

• Eliminates common vacuum leaks

• Restores correct idle and boost control

• Resistant to heat, cracking, and hardening

• Much longer service life than OEM rubber hoses

• Perfect for stock or modified GTI-Rs

SPECIFICATIONS

• Material: 3-layer silicone hose

• Construction: Reinforced, heat-resistant design

• Compatibility: GTI-R rear intake plenum vacuum system

• Durability: Significantly stronger than factory rubber piping

WHY THIS KIT EXISTS

This kit was developed because cost-effective replacement options simply didn’t exist locally. After struggling to source these hoses myself, I put together a complete, practical solution that actually makes sense for GTI-R owners on this side of the world.

WHAT’S INCLUDED

• 6 × Rear plenum intake vacuum hoses

✔️ Sold as a complete 6-piece replacement kit

WHY REPLACE NOW?

A failed vacuum hose can cause:

• Rough idle

• Lean running

• Boost leaks

• Poor drivability

Replacing them before they fail is cheap insurance for your GTI-R.
