Spool - High Performance Stainless Steel 10 Micron In-Line Filter Unit || N54/N55 (E9X/E8X/E6X)

Spool 10 Micron High-Performance Inline Fuel Filter Kit – E85 Compatible | 6AN

Protect your injectors. Unlock full fuel system flow.

The factory filter on Continental rotary HPFPs is tiny, restrictive, and prone to failure—especially under high-flow setups like the Spool Helix Overdrive System. These failures can lead to damaged injectors, leaky seals, and inconsistent performance.

✅ Why You Need It:

• Factory filters can rupture under pressure or become major flow bottlenecks

• High-flow builds (like Helix) demand clean, unrestricted fuel delivery

• Prevent fine particulate damage to HPFPs and direct injectors

🔧 Product Highlights:

• 10 Micron Stainless Steel Mesh Filter – Washable & reusable

• 100% E85 compatible – Built for ethanol-based fuels

• Flows up to 6 GPM – Over-engineered for high-output builds

• CNC aluminum filter housing

• Includes 6AN black nylon-coated, braided PTFE fuel lines

• Premium aluminum fittings included

• Replaces OEM rubber lines that are not ethanol safe

💡 Recommended Add-On for E85 Users:

Spool Wireless Ethanol Analyzer Kit

Pump E85 varies between 51%–85% ethanol, making tuning risky without knowing the true ethanol content. Pair your fuel filter with Spool’s Bluetooth Ethanol Analyzer Kit for real-time ethanol % monitoring.

Kit Includes:

• Continental inline ethanol sensor

• Spool Bluetooth analyzer module

• Plug & Play wiring harness

• 6AN PTFE, ethanol-compatible fuel lines

• FREE mobile app with E-content reading & blend calculator
  (Works even without the hardware for estimating blends)

📦 Fitment Note:

If your low-pressure fuel system is already modified, you may need a custom line kit for proper fitment. Contact us before ordering for compatibility assurance.
