Mazdaspeed 3 / 6 & CX-7 Turbo Oil Feed Line Kit | Garrett GT28R GT30R | 1.0mm Restrictor

Precision oil control for elite ball-bearing Garrett upgrades. Upgrading your 2.3L DISI engine to a Garrett GT-Series or GTX-Series dual ball-bearing turbo provides incredible response, but these cartridges are extremely sensitive to oil pressure. Without exact regulation, high pressure from the MZR block will overwhelm the seals, leading to blow-by and blue smoke. This GryphonTek Signature Series Kit provides the professional foundation: a -4AN PTFE Braided Line paired with a calibrated 1.0mm restrictor, ensuring your high-value Garrett investment stays healthy and smoke-free.

• 1.0mm Precision Metering: Features an integrated 1.0mm restrictor, specifically calibrated for Garrett ball-bearing cores to protect internal seals while ensuring optimal lubrication.
• -4AN PTFE Braided Construction: Replaces fragile rubber or rigid hardlines with a flexible, stainless steel braided PTFE hose that handles the extreme radiant heat of the DISI "Hot Side."
• Eliminate Sourcing Frustration: Includes the block-to-line and line-to-turbo adapters required for the 2.3L platform, saving you from the headache of hunting for mismatched fittings.
• Vibration Decoupling: Flexible architecture absorbs high-frequency engine harmonics, preventing the fatigue-cracking common in rigid OEM pipes during high-boost pulls.
