Detailed Description

Built for the BMW X3 cooling system, TYC 18142 is an intercooler designed around an aluminum core and crossflow configuration to manage compressed intake air through the charge-air circuit. The spring lock inlet and outlet connections help match the original-style plumbing layout, while the listed core dimensions support proper packaging in the vehicle’s front-end cooling stack. If you are replacing a worn or damaged BMW X3 intercooler, TYC 18142 provides a direct-reference option for 2015, 2016, and 2017 models. This part cross-references BMW OE number 17 51 7 823 571 and BM3012117 for the same application.

What It Helps Address

  • Charge-air cooling loss from a leaking or damaged intercooler
  • Boost pressure drop caused by cracked end tanks or core damage
  • Heat buildup in the intake charge under load
  • Fitment issues when replacing a failed BMW X3 intercooler
  • Service replacement needs for 2015-2017 BMW X3 cooling repairs

Installation Notes and Tips

Verify the inlet and outlet connection style, 61 mm diameter, and core dimensions before installation. Inspect adjoining charge-air hoses, seals, and clamps for wear before reassembly so the replacement intercooler can seal correctly. Confirm fitment against the vehicle’s cooling layout for your specific 2015-2017 BMW X3 configuration.

Quality Assurance

TYC manufactures replacement cooling components with OE-style fit and application-specific dimensions. TYC 18142 is cataloged for direct replacement use on the BMW X3 platform and should be matched to the vehicle’s original intercooler specifications before installation.
