When intake air temps rise, timing is pulled, boost is reduced, and the car simply stops delivering. CarBahn’s motorsport-grade bar-and-plate core helps stabilize temperatures under sustained boost so your X3\/X4 delivers the same punch on the third pull as it does on the first.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin: 0 0 18px; font-size: 16px;\"\u003e\n\u003ch3 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.2;\"\u003eBuilt for Real Performance Driving\u003c\/h3\u003e\n\u003cp style=\"margin: 0 0 10px;\"\u003eThis isn’t a cosmetic upgrade or a mild replacement.
