Detailed Description

Spectra Premium focuses on engineering, manufacturing technology, and quality control to produce filler necks that align with OE expectations. The FN1046 is intended for Acura TSX fitment from 2004-2008 and is suited for replacing a worn, rusted, or leaking filler neck without changing the vehicle’s fuel system layout.

Common Issues This Part Can Address

On Acura TSX applications, inspect surrounding fuel system components for corrosion or deterioration while the filler neck is removed.
