HKS 70019-AK112 Super Power Flow SPF Reloaded 200mm Wet Red Filter 100mm Inlet

Vehicle Fitment

• Universal - fits any vehicle or custom intake application with a 100mm (4") outer diameter intake pipe or turbo inlet

Fitment Notes

• Universal fitment - not specific to any year, make, or model; compatible with any intake system using 100mm (approximately 4") piping
• This is the complete SPF Reloaded Assembly (wet 2-layer red filter element + funnel housing + aluminum backplate) - it is not a filter-only replacement
• This is the wet/oiled red (2-row) version of the 200-100 assembly - for the dry green (3-layer, no oil required) 200-100 assembly, see HKS 70019-AK106
• The wet red filter type is pre-oiled from the factory and requires re-oiling after cleaning - do not use without oil or performance and filtration efficiency will be significantly reduced
• Designed for use with HKS vehicle-specific intake kits using 100mm piping, as well as standalone custom intake and large-diameter turbo inlet builds
• For other pipe sizes in the wet red 200mm format: 70mm inlet (70019-AK107), 80mm inlet (70019-AK111)

Features

• HKS Super Funnel inner design - the patented internal funnel geometry smoothly guides incoming air into the filter element, reducing inlet turbulence and promoting laminar airflow for consistent, efficient air delivery across the RPM range
• Wet 2-row (2-layer) red oiled polyurethane filter element - the oiled construction captures a higher volume of airborne particulates compared to a dry filter of equivalent flow area, while allowing a greater airflow rate than a paper element. The two-layer design balances filtration efficiency with low restriction for high-performance applications
• Oiled filter advantage - the oil layer on a wet-type filter acts as a chemical adhesive that traps and holds fine particles that may pass through the foam matrix itself, providing superior particulate capture in dusty or dirty environments
• Washable and reusable - the polyurethane element can be cleaned with appropriate filter cleaner, dried, re-oiled, and reinstalled repeatedly; replacement elements are not required for routine maintenance
• 200mm outer filter diameter - the largest standard filter body in the HKS SPF Reloaded lineup, providing maximum filter face area for the highest possible airflow capacity, suited to large-displacement engines and high-output modified builds
• 100mm (4") inlet diameter - mounts directly to 100mm intake pipes or large turbo inlets without adapters
• Hyper Stealth Frame - the Reloaded generation frame design increases air intake surface area by 27% over the previous Super Stealth frame generation, improving flow efficiency across the entire filter face
• Aluminum backplate with secured funnel outer edge - provides structural rigidity that prevents filter deformation under sustained high-velocity airflow and anchors the funnel assembly firmly to the backplate for long-term durability
• Engineered and manufactured in Japan by HKS to the same performance and quality standards as their vehicle-specific intake systems

Product Description

The HKS 70019-AK112 is the Super Power Flow (SPF) Reloaded complete filter assembly in the 200-100 wet red configuration - 200mm outer diameter, 100mm inlet, oiled 2-row red polyurethane - for use with any intake application using 100mm piping. As a complete assembly, it includes the HKS-patented inner Super Funnel housing, the two-layer oiled red polyurethane filter element, and an aluminum backplate. The 100mm inlet is the largest pipe size in the HKS SPF Reloaded lineup, making this the highest-flow configuration in the 200mm filter body series - well matched to large-displacement engines, highly modified turbo builds, and applications where intake restriction is a primary concern.

The wet 2-row (2-layer) red filter construction uses an oiled polyurethane matrix that provides superior particulate capture compared to a dry filter by using the oil layer as a chemical adhesive for fine particles that pass through the foam. This makes the Red wet variant the preferred choice in dusty or dirty operating environments - off-road use, track events with debris, or any situation where engine contamination protection is a higher priority than the maintenance simplicity of a dry filter. The trade-off is that the wet filter requires periodic re-oiling after cleaning, which must be done correctly to maintain both filtration efficiency and airflow performance. The Hyper Stealth Frame in the Reloaded generation represents a 27% improvement in air intake surface area over the previous Super Stealth frame, and the aluminum backplate with secured funnel outer edge prevents deformation and maintains the assembly's structural integrity under sustained high-airflow conditions.

The inner Super Funnel design - HKS's patented geometry that guides incoming air smoothly into the filter face - is shared across the entire SPF Reloaded lineup regardless of inlet size or filter type. This ensures the 70019-AK112 delivers the same laminar airflow benefit that defines the SPF series, reducing inlet turbulence and improving the consistency of air delivery to the engine. For the same 200-100 configuration in a dry green (no oil required) version, see HKS 70019-AK106. For the wet red format in smaller inlet sizes within the 200mm body, the 80mm version is HKS 70019-AK111 and the 70mm version is 70019-AK107.
