-12an 60 Micron Oil Filter w/Bypass

The Peterson Fluid -12AN 60 Micron Oil Filter with Bypass (Part No. 09-0452) is a high-performance in-line fuel and oil filtration system designed for motorsports applications requiring reliable contamination control. Built with a 60-micron stainless steel screen and AN threaded ports, this filter delivers precise filtration while maintaining flow integrity under demanding conditions. The integrated bypass valve safeguards engine protection by allowing oil circulation if the filter element becomes restricted, a critical feature in racing and high-performance driving scenarios where pressure spikes can occur.

The 400 Series aluminum construction with black anodized finish provides durability and corrosion resistance in harsh operating environments. Dual 12 AN male inlet and outlet connections ensure compatibility with standard motorsports fuel and oil line systems, while the compact 3.3 x 3.2 x 10.7-inch profile facilitates flexible engine bay installation. The 60-micron filtration rating removes contaminants while preserving the flow rates necessary for high-RPM applications, balancing protection with unrestricted fluid delivery. Weighing only 1.35 pounds, it adds minimal weight to fuel system configurations.

This filter suits road racing, drag racing, and engine rebuild applications where aftermarket filtration and AN plumbing are standard. The bypass feature is essential for cold-start conditions and high-flow demand situations common in competition engines. Buyers installing Peterson Fluid filtration systems appreciate the brand's reputation for precision manufacturing and the engineering standard expected in dedicated racing fuel systems.

Each unit ships individually, making it suitable for single-filter installations or system upgrades. Verify AN port compatibility and flow requirements with your engine management system before purchase to ensure optimal integration.
