BAGARAATAN N55 Charge Pipe Kit — F10 535i / F12 640i / F01 740i / E70 F15 X5 / E71 F16 X6

Precision matters at every connection point, which is why BAGARAATAN machines the throttle body flange from billet aluminum using CNC equipment. The result is a fitment that mirrors OEM tolerances while eliminating the micro-gaps that cause boost leaks on worn plastic fittings. Paired with throttle body-matched 3-inch piping, the kit keeps intake charge pressure exactly where it belongs — in the system, not bleeding off at a cracked seam. Drivers typically notice sharper throttle response and a meaningful reduction in turbo lag almost immediately after installation.

This kit also anticipates where many N55 builds go next. The integrated 1/8" NPT bung is pre-tapped and ready for a water-methanol injection nozzle, saving you the hassle of modifying pipes later if you decide to push the platform further. A replacement OEM C-clip is included in the box — a small but thoughtful addition that ensures you're not hunting for hardware mid-install if your original clip is damaged or missing.

Fitment covers the full spread of N55 3.0L applications: F10 535i and 535xi (2011+), F12/F13 640i and 640xi (2011+), F01/F02 740i, 740Li, and 740ix (2011+), E70/F15 X5 35i and 35ix (2010+), and E71/F16 X6 35i and 35ix (2008+). Both rear-wheel-drive and xDrive variants are covered. Note that professional installation is strongly recommended, as instructions are not included with this kit.
