BMW N54 Downpipe Fix 07-12 E90 E91 E92 08-10 E82 335i, 135i, 535i, X5, X6, Z4

Description

All items are tested and verified on a N54 engine before packaging.
Similar to BMS DPFix and the overpriced blue/black dp fix, but with a few improvements. This O2 Fix is built with genuine BMW connectors to protect your oem parts. Additionally, the yellow signal wires are coiled together like the oem signal wires to ensure magnetic interference doesn’t affect the signals. Most notably, this fix uses a more robust trim-pot with 25 turns of adjustment. The BMS DPFix and others use trim-pots with 1 turn of adjustment which can be thrown off by rough roads or off-road driving.
If you’re interested or have a question please message me. These are pre-adjusted to ensure your N54 can pass OBD readiness for both the catalyst and O2 sensor systems. FOR OFF-ROAD USE ONLY. Not intended to defeat, bypass, or render inoperative emissions control devices.
