Overview
The factory EA855 intake runners restrict airflow distribution across the five cylinders at high RPM and power levels. This CNC billet aluminium runner kit replaces the OEM pieces with more precisely machined alternatives — improving cylinder fill consistency and supporting higher-output builds.
Why Upgrade?
- CNC machined for tighter dimensional tolerance than factory cast runners
- Improved airflow distribution across all five EA855 cylinders
- Supports higher-power EA855 builds targeting consistent cylinder filling
- Direct replacement for the factory intake runners
Engineering Focus
CNC machined from billet aluminium — significantly tighter tolerances than the factory cast runners. The improved geometry supports more consistent airflow into each cylinder at elevated RPM and power levels.
Built for the Drive, Not Just the Dyno
Five cylinders means five chances for the factory runners to feed each one a little differently. Tighter machining tolerance is the kind of upgrade that doesn't show up in a spec sheet headline but shows up everywhere else — smoother power delivery, more consistent response across the rev range.
Fitment
Compatible with:
- Audi RS3 8V EA855 DAZA/DNWA
- Audi TTRS 8S EA855
Note: this runner kit fits the shared EA855 2.5T intake manifold across RS3 8V and TTRS 8S — same part, same fit. It does not fit standard A3/S3 8V (EA888) vehicles, which use a different manifold entirely. Verify your specific model before ordering, or message us your rego/VIN and we'll confirm it for you.
