Inline Oil Filter w/8an Fittings - Medium Length

The inline oil filter w/8AN fittings – medium length from SYSTEM ONE is purpose-built for custom engine builds, turbo installations, and high-performance modified vehicles where remote filtration, tight engine bay layouts, or aggressive plumbing demands a compact solution. Unlike traditional spin-on filters mounted directly to the block, inline configurations allow builders to position filtration away from heat sources and complex manifolds, improving serviceability and thermal management on street machines, track cars, and heavily modified street engines.

This medium-length unit features dual 8AN AN fittings, which are industry-standard adapters matching 1/2-inch SAE hose and AN line compatibility—the same plumbing standard used in fuel systems, power steering, and turbo oil supply circuits on professional builds. The compact 7.5-inch length fits into constrained spaces where traditional full-length housings cannot, while the robust aluminum construction and precision-engineered seals ensure reliable operation under sustained pressure and temperature cycling. The 8AN threads accept high-quality braided PTFE or steel-braided hoses, delivering superior durability and leak resistance compared to rubber fuel line alternatives.

This filter excels in forced-induction platforms—turbocharged and supercharged builds—where oil supply to turbo centers and remote coolers demands clean, regulated flow away from the engine block. Track enthusiasts and street rod builders benefit from easier oil changes without disturbing manifolds or cooling lines, while tuners running high-capacity oil coolers or multiple-pass circuits gain installation flexibility. Proper filtration media selection and correct AN line routing (matching OEM or tuner specifications for micron rating and flow capacity) ensure reliable long-term performance on modified engines operating at elevated boost levels or sustained high RPM.
