Performance Gains / Why It’s Needed

The stock B58 intake is prone to heat soak due to its location near the exhaust manifold. Eventuri’s sealed dual-feed carbon fibre intake reduces intake air temperatures while increasing volume and smoothing airflow. The result is faster turbo spool, improved throttle response, and consistent performance on spirited drives or track sessions.

FAQs

Q1: Will this fit stock turbo and airbox locations?
Yes. Designed to fit stock turbo and integrate with OEM airbox mounts.

Q2: Is tuning required?
No tuning required, but performance gains are enhanced with a B58 tune.

Q3: How does the dual air feed help?
It draws cooler air from the wheel arch while the sealed box reduces heat from the exhaust manifold.

Q4: Is the installation difficult?
Bolt-on with included couplers and brackets. Estimated time 1–2 hours.

Q5: Will this affect engine reliability?
No. Carbon fibre construction and heat shielding maintain safe operating temperatures.
