Upgrade from the stock BMW N20 / N26 charge pipe to the MAD N20 / N26 charge pipe for maximum airflow and reliability! The stock BMW N20 / N26 charge pipe is plastic and prone to failure. It's only a matter of time before the charge pipe to break. The MAD N20 / N26 charge pipe is a strong aluminum piece; it will provide better airflow and won't fail, and fits like stock. The MAD charge pipe retains the BMW C-clip and O-ring for the best fitment. Do not forget to move them from the stock charge pipe to the MAD option. The MAD charge pipe comes with two meth bungs; both bungs are sealed. If you do not intend to use methanol injection, keep them closed. Features: Better airflow More robust material (aluminum vs. plastic) Two meth bungs Lifetime warranty on defects and fitment 90 day return period All orders ship in 1-2 business days Spot on fitment   Fitment BMW 1 Series F20 (07/2010–02/2015), F20 LCI (05/2014–06/2016) – 125i & 125i xDrive (2014–2016) N20 & N26 F21 (07/2010–02/2015), F21 LCI (09/2014–06/2016) BMW 2 Series F22 (10/2012–06/2016), F23 (04/2014–06/2016) – 220i, 220i xDrive, 228i, 228i xDrive (2012–2016) N20 & N26 BMW 3 Series F30 (02/2011–01/2016), F30 LCI (10/2014–10/2018) F35 (06/2011–08/2015), F35 LCI (01/2015–08/2016) F31 (07/2011–06/2015), F31 LCI (12/2014–06/2016) F34 GT (11/2012–06/2016) 320i, 320i xDrive, 328i, 328i xDrive (2012–2018) N20 & N26 BMW 4 Series F32 (11/2012–01/2017), F33 (03/2013–02/2017) – 420i, 420i xDrive, 428i, 428i xDrive (2012–2018) N20 & N26 BMW X Series X3 F25 (02/2011–08/2017) – 18i, 20i, 20i xDrive, 28i, 28i xDrive (2012–2018) N20 & N26 X4 F26 (05/2013–03/2018) – 20i, 20i xDrive, 28i, 28i xDrive (2012–2018) N20 & N26 SKU: MAD-023
