N55CAI
The ARM N55 Intake increases airflow to your N55 turbo by expanding and streamlining piping from the air filter to the turbo inlet. The ARM N55 Intake comes complete with our heat shield which creates a strong seal with your hood to separate the hot air around the engine, from the cool air being pulled in by the OEM air snorkel. The ARM N55 Intake utilizes a dry multimedia inverted filter to clean the air passing into the turbo.
The ARM N55 Intake utilizes precision CNC machined fittings for the MAF sensor and vacuum line for easy reinstallation of these OEM components.
The ARM N55 Intake runner tube measures an oversized 3.5" at the air filter which then reduces down slightly to 3.3" to connect to the OEM N55 turbo inlet, or any aftermarket turbo inlet. The intake runner tube also incorporates a mounting bracket which is secured with the included mount to reduce vibrations commonly found with non-secured N55 intake kits. 
The ARM N55 Intake includes a heat shield to maximize the amount of cool air being pulled in by the intake from the OEM intake snorkel. The OEM intake snorkel directs cool air from outside the engine bay to the inside of the engine bay behind the driver side headlight where the ARM N55 Intake air filter is positioned.
The heat shield included in the ARM N55 Intake maximizes the amount of that cool air being drawn in by separating it from the hot air generated by the engine. The heat shield measures 1.6mm thick and has 3 mounting points that secure it into place. It also includes thick rubber weather stripping which is used to line the top and sides of the heat shield to prevent the hot air from passing through.
The ARM N55 Intake has a total filter surface area of 186 cubic inches with its inverted filter design. Making it capable of supporting even the most demanding big-turbo builds. If you're starting off with a stock turbo, but plan to upgrade your turbo in the future you can rest easy knowing that the ARM N55 Intake can grow with your build!

United StatesAmazing! The intake sounds sick and my single turbo’s singing like it’s got a blow-off valve haha. All jokes aside, the intake was super easy to install and the black filter looks really smooth with the rest of the engine bay. Only thing I will say is the heat shield is a definite must-install since these engines tend to run very hot especially now with the summer coming. Heat shield was slightly tedious but not too much of a bother to install at all!
United StatesFast shipping and part was fairly easy to install. No issues with working with my aftermarket inlet either.
United StatesFast delivery and part fit with ease
United StatesCAI sounds amazing. Highly recommend
United StatesHaving owned multiple N55 power BMW’s I can say the ARM intake surprised me. The closest thing I could compare it to is the MST intake, but at almost half the cost! This intake sounds and feels exactly like my MST intake felt on my F30 N55. I recently installed this on my F22 M235i, switching away from the BMS intake I had and all I can say is wow! The car pulls harder and overall feels more alive. I don’t have a lot of complaints but I’m at committed to leaving honest feedback to help the community when making upgrade decisions. The only piece of feedback I have to the development team would be to review the heat shield mounting locations. The install guide suggests that you need to ditch the DME cover. While it is a very tight fit, you can install the heat shield while retaining your DME cover.
