This ARM F3X N55 Charge Pipe is designed for RWD N55 cars that are on the list below. If you have an AWD F3X N55, you'll need our AWD F3X Charge Pipe.
Overall the kit is great, but there were two small issues during the installation. The O-ring provided is slightly thicker than the OEM and it did not allow me to push the charge pipe into the throttle body. I had to reuse the old one. Second, the provided adjustable clamps that hold the pipe sections together are not the same size. One is slightly smaller than the other which made it very difficult to put it together. I had to fight with the smaller one to make it fit. The larger one was the right size. They should both be of the same size since both pipe ends connected by the silicone adapter are the same diameter. The charge pipe is now installed and working well. The aluminum material in this charge pipe expands much better than the OEM plastic charge pipe, when then engine is warm the turbo pressure does not seem to fade.
Bought this for my 2013 335i rwd. The fit and finish is amazing. They sent me with one clamp a different size. Contacted them and they fixed the problem right away and I received the clamp two days later. Top notch customer service and products, 100% would recommend.
Hope to get time to install the parts soon, shipped fast and the quality of the parts look great
ordered this after my oem pipe blew up on stock power, the price was competitive in comparison to other similar products so I took a shot in the dark and got it, ordered the awd accidentally but with a call was fixed promptly. fitment was spot on and i was pleasantly surprised with the quality of the product was in person. so far so good, im still stock but car runs great now with no codes. Will definitely be getting the remaining upgrades from them and they have my recommendation.
I was sent a different sized o ring and a weird upper charge pipe. No questions asked, they sent me both of these things when i explained my situation, arrived in 2 days. This is great customer service!
