22RPD - E46 M3 Intercooler Brackets (E46IB)

E46 Intercooler Mounts — Treadstone-Compatible

These intercooler mounts are the result of years of hands-on development and refinement within the E46 platform. Designed for strength, precision, and compatibility, we believe this is the best solution available for mounting a high-performance intercooler on your E46.

Key Features:

• Laser-cut and CNC brake-formed in the USA for perfect fitment and finish

• Designed for Treadstone side-mount intercoolers

• Multiple mounting patterns support intercoolers up to 4.5" thick

• Utilizes factory frame rail mounting points — no guesswork required

• Includes one driver-side and one passenger-side mount

• No hardware included unless purchased with an intercooler

Intercooler Compatibility:

• Tested with TR8 / TR8L, TR1235, and TR1245

• Supports high-power builds — these intercoolers have been tested beyond 1000whp and 50psi in both drag and circuit racing environments

Why These Intercoolers Matter:
Treadstone intercoolers are in a league of their own — 4x heavier than standard budget options due to their superior fin density and thermal mass. That means:

• Greater heat-sinking capacity

• Better charge air cooling

• Improved durability under extreme load

If you’re serious about making power, these intercoolers and mounts are your best bang for the buck.

Fitment Notes:

• Factory AUX fan must be removed

• Trimming of bumper support required for larger core sizes
