4AN Oil Feed Flange Adapter Kit With Restrictor For T3/T4 Turbochargers

Turbo builders and performance enthusiasts, this 4AN oil feed flange adapter is crucial for proper turbocharger lubrication! Made from CNC machined T6061 billet aluminum, this kit includes the flange, gasket, and two M8x1.25 stainless steel bolts for complete installation. The built-in restrictor is perfect for ball bearing turbos that require controlled oil flow - though you can drill it out for journal bearing applications. Fits T3, T4, T35, T40, and most T-series turbochargers commonly used in performance builds. The thick 8mm flange design prevents leaks and provides durability under high temperatures and pressures. Proper oil feed is critical for turbo longevity - too much pressure can damage seals, while too little can starve the bearings. This adapter gives you that professional-grade solution for connecting your AN-style oil lines to the turbo housing. Installation is straightforward if you're familiar with turbo systems - just remove the old fitting and bolt this one in place with the included gasket. The quality is excellent with precise machining that ensures proper fit and seal. Whether you're building a new turbo setup or upgrading your existing oil feed system, this adapter provides reliable performance and peace of mind. Your turbo will get the proper oil flow it needs for long life and consistent performance. Much better than makeshift solutions that can lead to oil leaks or turbo failure. Your performance build deserves proper oiling components, and this 4AN adapter delivers professional results!
