What turbo inlets do
The turbo inlet is the short piece between the airbox and the compressor housing. OEM inlets are ribbed plastic or silicone — quiet, cheap, and noticeably restrictive once airflow demand climbs. A smooth-bore alloy or reinforced silicone inlet removes the restriction, smooths flow into the compressor wheel, and on the IS38-equipped MQB platform delivers a clear measured gain as part of the broader hardware pathway.
Why it matters
- 01Smooth-bore vs OEM ribbed — measurable flow gain
- 02Reinforced silicone or alloy construction (no swell under boost)
- 03Pairs with intake + downpipe to complete the flow path
- 04Critical in the Stage 2 hardware pathway — OEM inlet becomes the bottleneck
Platform relevance
Where it counts most.
Biggest impact on EA888 Gen 3 & Gen 4 (IS38), EA855 Evo, B58 and S58 — all run restrictive OEM inlet pipes.
