🛠️ Description

After a full year of development, I’m proud to introduce Version 2.0 of the Tuning3D 75° Cold Air Intake for the Mazda MX-5 NB.

This updated version brings major improvements in airflow, modularity, and ease of installation – making it a true plug & play performance upgrade for stock and lightly modified cars.

💨 Optional upgrade

You can enhance your intake even further with the Velocity Stack Add-on, which improves airflow smoothness and throttle response.

Plug & play installation – no cutting, no permanent modifications.

🔧 Filter Compatibility (Important)

When mounting the air filter directly to the MAF, use a filter with a 70 mm inlet diameter.

Headlight shape limits the maximum filter size.

Pre-facelift MX-5 NB (NB1, 1998–2000):

• Maximum filter length: 150 mm (absolute limit)
• Recommended: 140 mm or shorter for guaranteed clearance

Facelift MX-5 NBFL (2001–2005):

• Larger headlight clearance
• Filters up to 160 mm fit safely
• Standard cone filters (150–160 mm) work normally

These measurements apply when using the intake without the Velocity Stack Add-on.

🔥 Why choose V2 over cheap short intakes?

• Proven dyno gains on a stock engine
• No power loss anywhere in the rev range
• Heat-resistant automotive materials (not PLA)
• Designed specifically for MX-5 NB engine bay
• Fully reversible OEM-friendly install
• Developed and tested on a real car – not just CAD
