LRT K979 Manifolds

LRT K979 Exhaust Manifold

The LRT K979 is a high‑performance exhaust manifold designed specifically for the Mitsubishi Colt VI 1.1 Smart Forfour and its variants (Z3, Z2). It replaces the stock manifold with a lightweight, durable solution that improves engine breathing, increases horsepower, and delivers a more aggressive exhaust note.

Key Features

• Material: Stainless steel construction ensures corrosion resistance and longevity even under high‑temperature conditions.
• Design: The manifold incorporates a tuned exhaust path that optimizes backpressure, enhancing torque across the entire rev range.
• Compatibility: Engine codes: MITSUBISHI COLT VI 1.1, SMART FORFOUR 1.1, Z3, Z2. The part is engineered to fit the original mounting points without modification.
• Installation Kit: Comes with a complete set of bolts, gaskets, and an installation guide for a tool‑free setup.
• Performance Gains: Users report up to 5–7 hp increase in peak power and a noticeable lift in torque at mid‑range RPMs.
• Sound: The manifold’s geometry produces a deeper, more resonant exhaust tone that complements the Smart Forfour’s compact chassis.

Technical Specifications

Installation Procedure

1. Preparation: Warm the engine to operating temperature, then disconnect the battery for safety.
2. Remove Stock Manifold: Loosen and remove the bolts securing the stock manifold. Carefully detach the exhaust pipe connections.
3. Install LRT K979: Position the new manifold onto the cylinder head, aligning all mounting points. Tighten bolts to the manufacturer’s torque specification (typically 12–15 Nm).
4. Reattach Exhaust: Connect the exhaust pipe to the new manifold using supplied gaskets.
5. Final Checks: Verify that all connections are secure, then reconnect the battery and start the engine. Listen for any leaks or unusual noises.

Benefits Over Stock Manifold

• Improved Engine Efficiency: The optimized flow path reduces restriction, allowing the engine to breathe more freely.
• Enhanced Durability: Stainless steel construction resists rust and heat damage, extending service life.
• Weight Reduction: Lighter than many aftermarket options, contributing to better vehicle dynamics.
• Easy Installation: Designed for a quick swap without the need for custom machining.

Customer Feedback

Owners of the Mitsubishi Colt VI 1.1 Smart Forfour who have installed the LRT K979 report noticeable improvements in acceleration and a richer exhaust tone. Many note that the manifold’s performance gains are achieved without compromising reliability or daily drivability.

Compatibility Summary

The LRT K979 is specifically engineered for:

• Mitsubishi Colt VI 1.1 (including Z3 and Z2 variants)
• Smart Forfour 1.1 models
• Other vehicles with identical engine block geometry and exhaust manifold mounting points

Maintenance Tips

• Inspect the manifold for cracks or dents after any collision.
• Check gasket seals annually to prevent exhaust leaks.
• Avoid using high‑temperature lubricants on the bolts to preserve torque integrity.

Conclusion

The LRT K979 Exhaust Manifold delivers a compelling blend of performance, durability, and ease of installation for Mitsubishi Colt VI 1.1 Smart Forfour enthusiasts. Its stainless steel construction, optimized flow design, and comprehensive installation kit make it an attractive upgrade that enhances both power output and exhaust character without sacrificing reliability.
