Oil Thermostat Delete Plate For BMW 135i 335i 535i Z4 N54 N55
The Oil Thermostat Delete Plate for BMW 135i, 335i, 535i, and Z4 models with N54 or N55 engines removes the factory restriction in your lubrication circuit and establishes a straight-through fluid path. By eliminating the stock thermostatic valve, this component enables direct routing to larger aftermarket oil coolers and remote filtration systems, addressing the common issue of elevated oil temperatures during aggressive driving, extended highway runs, or track sessions. Crafted from solid T-6061 billet aluminum, each unit undergoes precision CNC milling, surface anodizing, and machine engraving to deliver durable corrosion resistance while preserving a clean, factory-finished appearance under the hood.
Benefits & Tips
Installing this delete plate gives you predictable thermal control and maximizes cooling capacity when paired with an upgraded oil cooler setup. To maintain optimal oil pressure after shutdown, consider pairing the upgrade with an oil pressure kit or adjusting idle time before turning off the engine. Apply medium-strength threadlocker to all mounting fasteners to抵抗 vibration fatigue, and trace your custom AN or braid lines before final tightening to prevent contact with moving components like pulleys or the alternator.
