HKS Super Power Flow (SPF) Replacement Filter Element – 150mm | 2-Row | Wet Type | Red

Keep your HKS Super Power Flow intake system performing at its best with the HKS SPF Replacement Filter Element — the genuine HKS replacement element for SPF intake systems using the 150mm diameter, 2-row filter configuration. This wet-type filter element is the correct service replacement for HKS SPF intakes requiring the 150mm / 2-row specification, maintaining the SPF system’s high-flow filtration performance and protecting your engine from contaminants. In red for a clean, distinctive appearance in the engine bay.

Key Features:

• Genuine HKS replacement element — OEM HKS filter element for SPF intake systems, ensuring correct fitment and performance
• 150mm diameter — fits HKS SPF intake systems using the 150mm filter specification
• 2-row (double layer) construction — dual-layer filter media for improved filtration efficiency and increased filter surface area
• Wet type — oil-wetted filter media for superior particle capture and high-flow filtration performance
• Red colour — distinctive red filter element for a clean, high-performance appearance in the engine bay
• HKS quality — genuine HKS part engineered to the same specification as the original SPF system filter

Performance Benefits:

• Maintained SPF System Performance: A fresh, correctly specified filter element restores the HKS SPF intake system to its original high-flow filtration performance — a clogged or degraded filter element restricts airflow and reduces the intake system’s performance benefit
• Wet-Type Filtration Efficiency: Oil-wetted filter media captures fine particles more effectively than dry filter media at equivalent airflow restriction — providing superior engine protection while maintaining the high-flow characteristics of the SPF intake system
• 2-Row Filter Surface Area: The dual-layer construction increases the filter’s effective surface area, improving both filtration capacity and airflow capacity versus a single-layer element
• Engine Protection: Regular filter element replacement ensures the engine continues to receive clean, filtered air — preventing the abrasive particle ingestion that causes accelerated engine wear

Specifications:

• Brand: HKS
• Part Number: 70001-AK031
• Compatible System: HKS Super Power Flow (SPF) intake
• Diameter: 150mm

Compatibility:

• Compatible with HKS Super Power Flow (SPF) intake systems using the 150mm / 2-row filter specification
• Note: Verify your specific HKS SPF intake system’s filter specification (diameter, row count, and filter type) before ordering. HKS SPF systems are available in multiple filter sizes and configurations — confirm the 150mm / 2-row / wet specification matches your intake system before purchasing.
• Refer to your HKS SPF intake system’s documentation or HKS’s parts catalogue for the correct replacement element part number for your specific system

What’s Included:

• HKS SPF replacement filter element – 150mm, 2-row, wet type, red (70001-AK031)

Installation & Maintenance Notes:

• Remove the existing filter element from the SPF intake housing
• Clean the intake housing before installing the new element
• Install the new element and ensure it is correctly seated and secured in the housing
• Wet-type filter elements should be re-oiled periodically — use HKS filter oil or a compatible filter oil product
• Replace the filter element at the interval recommended by HKS or when the element is visibly contaminated and cannot be cleaned effectively
• Do not over-oil the filter element — excess oil can contaminate the mass airflow sensor (MAF) on MAF-equipped vehicles

HKS Super Power Flow (SPF) Intake System:

The HKS Super Power Flow (SPF) is one of HKS’s most iconic intake products — a high-flow pod-style intake system featuring a distinctive mushroom-shaped filter housing that has been a staple of JDM engine bays since the 1990s. The SPF’s large-diameter filter element and optimized housing design deliver improved airflow over the factory airbox, with the distinctive induction sound that has made it a favourite among JDM enthusiasts. Regular filter element replacement is essential for maintaining the SPF system’s performance and protecting the engine — a clogged or degraded element restricts airflow and negates the intake system’s performance benefit.

Wet vs. Dry Filter Elements:

Wet-type filter elements use oil-wetted cotton or synthetic media to capture airborne particles. The oil coating on the filter fibres creates a tacky surface that traps fine particles more effectively than dry media at equivalent airflow restriction — providing superior filtration efficiency while maintaining high airflow. Wet filters require periodic re-oiling as part of their maintenance routine, but can be cleaned and re-oiled multiple times before replacement. The HKS SPF wet element is the correct specification for SPF systems designed for wet-type filtration — do not substitute a dry element in a system designed for wet-type media without verifying compatibility.

Why HKS?

HKS (Hasegawa Kikaku Seisakusho) has been producing high-performance aftermarket parts for Japanese performance vehicles since 1973 — one of the most respected and recognized names in JDM performance. Their Super Power Flow intake system is one of their most iconic products, with decades of development and a loyal following in the JDM enthusiast community. Using genuine HKS replacement elements ensures the SPF system continues to perform to its original specification — aftermarket substitute elements may not match the correct dimensions, filtration efficiency, or flow characteristics of the genuine HKS part.

Perfect For:

• HKS SPF intake system owners requiring a genuine replacement filter element in the 150mm / 2-row / wet specification
• Scheduled maintenance on HKS SPF intake systems where the existing element is due for replacement
• SPF system owners who want to keep a spare filter element on hand for quick maintenance turnaround
• Anyone restoring or refreshing an HKS SPF intake system with a genuine OEM-specification replacement element

Pro Tip: Keep a spare filter element on hand so you can swap to a fresh element immediately and clean the used one at your convenience — rather than having the intake system out of service during the cleaning and drying process. Wet filter elements need to dry completely after cleaning before re-oiling and reinstalling.

Note: Verify the 150mm / 2-row / wet specification matches your HKS SPF intake system before ordering. Do not over-oil the element after cleaning — excess oil can contaminate the MAF sensor. Use HKS filter oil or a compatible product for re-oiling.
