I installed a VRSF 7inch intercooler recently, all went well and the intercooler and components fit well with trimming of the black plastic inner bumper on X1 35i M Sport, N55. I have made several full boost runs since the install and all feels great and the intake temps only increased by a couple degrees. The stock intercooler does a good job handling normal boost, but when you do a pull at 17psi+ the intake temps go up quite a bit.
I decided on the 7in VRSF because I wanted to give the front end a better look and the extra 2 inches really help make the intercooler more visible from the front inside the M Sport bumper. The clamps and piping work well and fit up just fine. I have an ER Charge pipe and that worked well with the VRSF upper intercooler pipe. As with any intercooler install, you have to think it through and position t-bolt hose clamps in a direction that can be reached to tighten. I did the install by myself and used jacks and jack stands to raise the front of the car in my garage. All in all it was a few hours and most of the time was spent cutting and trial fitting the intercooler. The stock intercooler can be removed in 15 minutes! If the 7in fits I am sure all of the other 5in intercoolers would be a breeze to install.
I don’t know of any other 7in intercooler installs on the X1 35i so I wanted to give everyone a heads up that it is possible and works great, just need to cut(dremel tool and tin snips) about 2 inches of material off the black bumper plastic then your good to go! Very pleased with the product and Tiago at VRSF has been helpful and part of the BMW community for a while and has great products at competitive prices. You'll see great reviews of his producs from 135 or 335 guys on those forums.
