Inline Fuel/Oil Filter S et (Size: -4AN)

The Inline Fuel/Oil Filter Set (Size: -4AN) from VIBRANT PERFORMANCE is purpose-built for fuel and oil system applications where reliable filtration and flow control are non-negotiable. Designed for automotive enthusiasts, engine builders, and performance shops, this kit addresses the critical need for clean fuel delivery and oil circulation in high-performance and custom engine builds. The -4AN sizing indicates compatibility with standard -4 AN hose and fitting systems, making it a drop-in solution for custom fuel rails, oil cooler lines, and auxiliary fuel systems where OEM filtration is insufficient or unavailable.

This kit features three selectable filter screens (30, 80, and 150 micron ratings), allowing users to choose the optimal filtration level for their specific application and flow requirements. The aluminum body construction is black anodized for corrosion resistance and durability in engine bay or underbody environments. The adapter-style inline design allows for seamless integration into fuel lines or oil circuits without requiring complex manifold modifications, while the multiple micron options enable tuning between maximum flow and maximum protection—a critical balance in forced-induction and high-RPM applications. The compact footprint (4.15 x 1.65 x 4.55 inches) and lightweight design (0.11 lbs) ensure easy installation in tight spaces common to custom fuel systems and engine swaps.

This filter set is ideal for EFI conversions, turbocharged and supercharged engine builds, custom fuel system installations, and oil cooling system setups where component protection is essential. The -4AN fitting standard ensures broad compatibility across fuel injector supply lines, carbureted high-flow fuel systems, and aftermarket oil cooler plumbing. Installers should verify line routing and pressure specifications to select the appropriate micron rating; finer screens (30 micron) provide maximum protection but increase backpressure, while coarser screens (150 micron) maximize flow for naturally aspirated applications. The kit's modular screen design allows field swapping without system disassembly, making it an adaptable choice for development and testing phases.
