do88 Audi RS3 (8V/8Y) / TT RS (8S) Throttle Body Spacer

The factory throttle body spacer on the RS3/TT RS isn't optimised for good airflow, it has a large internal groove that causes genuinely uneven air distribution between the throttle body and the intake manifold. do88's replacement fixes this directly with a smooth internal bore for better, more even airflow.

Machined from a solid block of 6063 aluminium using CNC precision, finished in a matte black anodisation, this spacer fits perfectly as a direct replacement for the original part. Two 1/8-27 NPT ports are included, ideal for water-methanol injection or as a boost/vacuum reference point, with plugs supplied if you don't plan to use them.

Works with: OEM mounting points. Direct bolt-on replacement.
