Oil Restrictor Fitting -4AN x 7/16-24in

The Oil Restrictor Fitting -4AN x 7/16-24in from Vibrant Performance is a vital component for turbo and supercharged engine builds where precise oil flow control is essential.

Designed with precision engineering, this -4AN x 7/16-24in fitting is built to handle high-pressure oiling circuits found in modern forced-induction systems. The -4AN connection accommodates standard -4 braided oil lines commonly used in turbo feed applications, while the 7/16-24 inch thread pitch ensures secure installation into engine blocks or aftermarket oil supply blocks.

This oil restrictor fitting is indispensable for track builders, tuners, and enthusiasts pushing aggressive boost levels or running unconventional setups. Its compact design allows it to fit into tight engine bay configurations without requiring extensive modifications, making it a practical choice for any performance-oriented engine build.
