Frequently Asked Questions
Q: Will this fit with my factory intake and turbo?
A: Yes, this is a direct bolt-on replacement for the factory Y-bridge and works with stock intake manifolds and turbochargers.
Q: Do I need a tune after installation?
A: No tune is required, but a custom tune will maximize the gains from the increased airflow.
Q: Is the resonator delete necessary for performance?
A: The resonator delete block is primarily an engine bay cleanup modification — it removes a potential boost leak point and frees up space for other mods.
Q: What's the difference between this and the combo kit (ER-0198)?
A: This is the intake elbow bridge only. The combo kit (ER-0198) includes the EGR valve and cooler delete components as well.
