LS1 Remote Oil Filter Adapter

The LS1 Remote Oil Filter Adapter is a bypass-style filtration component engineered for LS-platform engine builds where conventional in-block filter housings create clearance conflicts or routing complications. Whether you're working with tight engine bay layouts, custom fabrication projects, or high-flow cooling system designs, this remote adapter relocates your oil filtration away from the block, streamlining plumbing and maximizing accessibility for maintenance. Built for serious enthusiasts and performance shops who demand flexibility in their engine modifications.

Constructed from aluminum and finished in black anodize for corrosion resistance, the LS1 Remote Oil Filter Adapter features a 13/16-16 inch center thread inlet designed to mate with standard remote filter housings, paired with dual 1/2 inch NPT female ports for inlet and outlet plumbing. The bypass design allows unfiltered oil circulation at startup or under high-viscosity conditions, protecting critical bearing surfaces during cold cranks while the filter media loads. Its compact footprint—measuring 7.5 x 3 x 8.25 inches—positions easily in engine bays without interfering with turbocharger piping, fuel rails, or accessory brackets common in modified LS1 installations.

Ideal for LS1, LS2, LS3, and LS7 engine swaps, this adapter pairs seamlessly with remote-style filter canisters and works with any hose-compatible plumbing configuration—AN fittings, stainless steel tubing, or traditional rubber hose. Installation requires basic NPT fitting knowledge and appropriate sealing compound; dry-seal fittings are not recommended for this application. Weighing just 1.4 pounds, it adds negligible mass while eliminating the packaging complexity of traditional cartridge filters in tight custom builds.
