13717577469 Suction Pipe | Fluid Dynamics & Structural Integrity

Designed for N20/N55 engine configurations, the 13717577469 Suction Pipe features injection-molded PA66-GF25 material with integrated vibration dampers. Its dual-seal architecture maintains 0.05mm dimensional stability across thermal cycles (-30°C to 150°C). The radial reinforcement ribs increase burst pressure resistance by 40% compared to standard designs.

Flow-optimized internal geometry reduces turbulence by 22% at 3,500 RPM. Chemical-resistant surface treatment withstands oil vapors and PCV byproducts. Pre-installed mounting brackets ensure ±0.8mm alignment accuracy during service installations. The thermal barrier coating prevents heat soak distortion in stop-and-go driving conditions.
