22RPD N52 Trumpets – Now in Production

After years of development, we're proud to release the most complete, tested, and performance-focused intake system available for the N52 platform. Preorder is now closed, and production is underway. Inventory is expected soon.

We’ve moved to German manufacturing for unmatched quality, precision, and reliability. Pricing has been updated to interim rates as we navigate tariff laws and other international factors. Final retail pricing may change once these settle.

Options

Trumpets Only

Injection-molded trumpet stack system
Designed for our lid or custom builds
Includes DXFs for fabricating custom lids (dual plenum, supercharger, turbo, etc.)
We are in development with ITG of a bolt-on Race-Panel-Filter (sold separately, cleanable and reusable), expected to be available for order any day.

Trumpets + Lid

Matched injection-molded lid with MAP, EVAP, PCV, and OEM-style throttle flange
Drop-in fit with most N52 setups (MAP/EVAP routing may require minor adjustment) We intend to create better solutions for this in the coming days.
OEM-like integration with your airbox and filter of choice. We intend to release a few variations of silicone couplers for order to direct match these to oem and oem style filter box options.

Why Ours?

Designed to use OEM lower gaskets and hardware
OEM-style metal inserts – torque to spec, no cracking
Smooth internal finish for optimized flow
Textured outer surface for heat resilience and structure
FEA-verified to handle boost; real-world testing ongoing

Software Compatibility

Fully compatible with our lidded systems; supports beta “Party Mode” tunes
Some AWD or automatic ECUs may enter limp mode when run without a lid
Party Mode tuning is still in beta, and support without a lid is not guaranteed — we are actively improving compatibility
If software incompatibility arises, you can always upgrade to a lidded system for optimal support

Vehicle Fitment

Fits all N52B30 variants (N52K, N52N)
Also fits N51 and N53 (lid required for N53)
OEM B30 port geometry – not for B25 heads (without porting)
Tested on E9X, E8X, E6X, E89, E70 platforms
Compatible with OEM or N54 throttle body

Boosted Note

FEA testing shows the trumpets can handle boost, but real-world durability depends on your setup. Testing continues – share your results!
