The factory air intake on the RB25DET in the R33 GTST and R34 GT/GTT creates noticeable restrictions that limit throttle sharpness and turbo efficiency. The HKS Racing Suction Intake Kit (70020-AN104) is a premium upgrade that replaces the restrictive stock system with an advanced Hyper Stealth Frame design. This innovative frame increases the air intake surface area by 27%, delivering significantly improved airflow efficiency and a steady supply of clean, unobstructed air to the turbocharger for sharper throttle response and stronger power delivery across the RPM range.
The kit features a high-quality aluminum backplate that firmly secures the funnel for maximum rigidity and durability under high-boost conditions. An Alumite treatment enhances the surface quality while providing a sleek black finish that adds a premium look to the engine bay. Unlike the stock system with its corrugated hoses that generate turbulence and resistance, the specially designed pipe in this HKS kit minimizes internal gaps and restrictions, resulting in smoother airflow, reduced suction losses, and better overall engine breathing.
At Terra Firma Automotive, we supply this genuine HKS Racing Suction Intake Kit as a premium upgrade for R33 GTST and R34 GT/GTT owners seeking better intake efficiency and performance.
