HKS Racing Suction Reloaded Cold Air Intake Honda Civic Si 2017-2020 | 70020-KH101

The HKS Racing Suction Reloaded (70020-KH101) is a high-performance cold air intake system engineered specifically for the Honda Civic Si. Designed by HKS — one of Japan's most respected performance tuning brands — this intake system replaces the restrictive factory airbox to deliver a more direct, unrestricted airflow path to the engine. Whether you're building a street-driven Civic Si or pushing it on the track, the Racing Suction Reloaded is the definitive bolt-on upgrade for measurable power gains and an aggressive induction sound.

Key Features & Benefits

• High-Flow Air Filtration — HKS's signature dry-type or oiled performance filter dramatically reduces intake restriction compared to the OEM airbox, allowing the engine to breathe freely and produce more power across the RPM range.
• Mandrel-Bent Aluminum Intake Pipe — Smooth, mandrel-bent aluminum tubing eliminates turbulence-causing kinks and bends, maximizing airflow velocity from the filter to the throttle body for improved throttle response.
• Reloaded Design — The updated "Reloaded" iteration improves upon the original Racing Suction with refined pipe routing optimized specifically for the Honda Civic Si's engine bay, ensuring a precise OEM-quality fit without modification.
• Aggressive Induction Sound — Experience a throaty, performance intake note under acceleration — a hallmark of the HKS Racing Suction lineup that transforms the driving character of the Civic Si.
• Direct Bolt-On Installation — Engineered to use existing mounting points and OEM hardware locations, allowing for a straightforward installation without cutting, drilling, or fabrication.
• HKS Quality Construction — Built to HKS's exacting Japanese engineering standards with premium materials designed to withstand heat cycling, vibration, and the rigors of both street and motorsport use.
• Improved Throttle Response — Reduced intake restriction translates to a more immediate, linear throttle response — a noticeable improvement you'll feel on every spirited drive.
