Description

The HPS 57-1591-RED intake hose is a performance upgrade for the Nissan 2003-2006 350Z 3.5L V6. By improving airflow and reducing heat soak, the HPS intake hose allows the stock air box to perform at its peak efficiency. Installation is straightforward, with an estimated time of 45 minutes, and includes HPS industrial-grade 100 percent stainless steel t-bolt clamps for a secure fit. This upgrade delivers dyno-proven performance gains of +5.9 Whp and +5.5 Ft-lbs without requiring any re-tuning. Additionally, the HPS silicone post-MAF air intake tube is designed not to trigger a check engine light.
