1.8T Billet Aluminum Fuel Injector Cup Replacement Kit

Constructed from heat-sensitive plastic, your factory 1.8T fuel injector cups are prone to self-destruction. After years of constant exposure to engine heat, vibration, and chemical-laden fuel residue, cracks will form in the seat of the insert and create a multitude of issues. Boost and fuel leaks will eventually prompt a lean running condition, a rough idle, and multiple diagnostic trouble codes.

With these issues in mind, our engineering team set out to create an everlasting, performance-minded replacement for the factory insert. The result is a precision-machined piece crafted from 6061-T6 billet aluminum a material selected for its excellent strength, durability, and overall resistance to fatigue. Unlike the brittle OE plastic inserts, our billet cups are built to last under extreme stress, ensuring your injectors remain perfectly seated and aligned at all times.
