2.5-Inch Aluminum Flange Pipe With Adapter For VW Jetta/Golf/Beetle Map Sensor

Upgrade your VW/Audi 1.8T intake with a precision‑machined 2.5-inch (63 mm) aluminum flange pipe and adapter, designed specifically for the MAP sensor flange. Crafted from 6061‑T6 billet aluminum, this durable flange delivers a tight, leak‑free seal that helps your MAP sensor read manifold pressure accurately, improving throttle response and engine efficiency.

Designed to fit Jetta, Golf, Beetle, and Audi A4 1.8T engines from 1998–2005, this 2.5" flange pipe pairs a standard inlet/outlet with a universal MAP sensor flange. The 63 mm diameter matches common sensor ports, providing a robust, corrosion‑resistant connection that withstands daily driving and performance setups alike.

With ISO 9000 certification and a universal model name, you can trust the build quality and compatibility across compatible platforms. This aluminum flange helps minimize vacuum leaks and MAP sensor misreads that can throttle performance, while keeping weight down for easier installation and long‑term durability.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
