CTS Turbo O2 Pipe 1.8T (Transverse FWD)

The CTS Turbo O2 Pipe replaces the restrictive factory oxygen sensor pipe on 1.8T transverse front-wheel-drive engines fitted to MK4 VW Golf, Jetta and GTI models from 1999 to 2005. Mandrel-bent construction ensures smooth internal diameter throughout, eliminating the crimped sections found in OEM pipes that create turbulence and restrict exhaust gas flow. Built from quality materials to withstand elevated exhaust temperatures in modified applications, this pipe provides a more efficient path between the turbocharger and downpipe while maintaining proper sensor function for engine management.
