Product Description

The HKS 70019-AN109 Super Power Flow Air Filter is a performance-oriented intake upgrade engineered for Nissan Skyline ER34 and Stagea C34/WGNC34 equipped with the RB25DET NEO engine (model years 1998-2001). By replacing the restrictive stock airbox with a wider-induction, ambient-exposure filter, it significantly improves airflow - enhancing mid-range torque, throttle response, and overall engine efficiency. The 3-layer dry polyurethane filter ensures effective filtration while maintaining long service life, and the reinforced aluminum back plate and Hyper Stealth Frame provide durability even under spirited driving or modified engine use.

Installation is straightforward and bolt-on; no major modifications are required. Once installed, the engine enjoys improved breathing, a sharper throttle response, and a more aggressive induction sound typical of a performance turbo setup - making this filter a great choice for tuners, performance enthusiasts, or anyone wanting to extract more potential from their RB25DET-powered Skyline or Stagea.
