Conquer dunes, trails, and desert tracks with CB Performance’s Exclusive MX Off-Road Single IDF Kits, purpose-built for reliability, throttle response, and power — even in the harshest off-road environments.

Whether you’re building a sand rail, Baja bug, or a dedicated race car, these kits integrate legendary Weber carburetion with Premium-Quality Components. Each kit features a CBP Exclusive US-Made Low-Profile Center Section Manifold (details), CBP Exclusive Cable-Pull Linkage (details), and our US-Made Precision-Cast Air Filter Assembly with 6" Dual-Layer Foam Filters (details).

Single IDF Kits provide a simpler, budget-friendly option for stock and mild-performance engines, or for applications where dual carbs are impractical. MX Off-Road kits include exclusive features specifically tailored for off-road applications.

MX Only Features:
  • Uni-Foam Filters – 6” Dual-layer foam filter assembly with cleanable element for superior dirt and dust protection.
  • Float Bowl Vent – Reduce fuel slosh and spillage during rough terrain and aggressive driving (details).

Premium features don’t stop there, all CBP Single IDF carburetor kits include everything you need for a clean hassle-free install that delivers long-lasting, worry-free operation. See complete list of kit components below.

Key Features:
  • GENUINE Weber IDF Carburetor – Manufactured in Spain – No cheap knockoffs here. Built for precision, reliability, trusted by VW enthusiasts worldwide.
  • USA-Made Manifold – CBP Exclusive Low-Profile Center Section Manifold.
  • Strong & Reliable Design – The manifold bolts directly to the engine case for maximum support and stability.
  • USA-Made Air Filter Assembly – Heavy-Duty 356 Aluminum Alloy Air Filter Base and Top securely hold the Uni-Foam Element in place even while bashing through the rough stuff.
  • Exclusive Cable-Pull Linkage – CBP’s Sheathed Cable Linkage mounts directly to the CBP Single Air Filter Base (details) and delivers smooth, crisp throttle response and long-lasting reliability.
  • Velocity Stacks – Boost airflow and throttle response for immediate power delivery.
  • All-Weather Heat Risers – Full-Ascent Heat Risers provide essential carburetor heat, improving drivability and reducing icing in cooler conditions.
