Product Description:

-4 (-4AN) Size oil inlet restrictor fitting (0.035" orifice / hole size) for BorgWarner Turbochargers. Output is -4AN male flare. High durability and reusable Stainless Steel material.

Use with any -4AN oil feed lines with a -4AN female hose end!

Please Note: NEVER use thread sealant with this fitting. The fitting engages with the mating part and creates a "compression" seal once installed. Any type of liquid or thread sealant used will run the risk of plugging up the oil feed port causing oil starvation and failure of the turbo..
