In addition, the design of the inner neck of the ARM air filters has been molded in a conical shape to further increase airflow by reducing resistance as air is being transferred from the filters to the aluminum adapters before finally entering the turbo inlets.
With less restriction, the N54’s turbos can draw in air more efficiently allowing faster turbo spool. Power gains can be seen throughout most of the rpm range, but particularly above 5k rpm where full bolt-on N54’s can see as much as 20whp.
In addition to the performance benefits, the ARM N54 Dual Cone Intake kit also opens up the sound of your turbochargers. The OEM airbox is designed to decrease the sound of the N54’s turbos, but with the ARM DCI kit you can hear the sound of the turbos spooling up as they draw in air through the massive high-flow inverted filters.
The ARM N54 Dual Cone Intake fits either the stock N54 turbo inlets and any upgraded inlets that fit the OEM airbox.

every other brand has bright red cones which are kind of an eyesore in my opinion. Once I saw these, I knew I had to get them. Clean black design blends in perfect with the engine bay. The sound is also very balanced. I found that BMS and VRSF cones had very loud induction noises which got a bit annoying after a while. These ARM versions have a nice sound at low throttle but once you get on it you can really hear the turbos spool and ingest air. 10/10. Also fitment will not be perfect. I got the cone shaft in a few grooves on the oem inlets, but no biggie. They work perfectly
I got the DCIs and downpipes for my 2009 e93 335i. These two upgrades paired with a BMS chargepipe make the car sound much more aggressive while providing a decent performance boost!
Items arrived sooner than expected. Very prompt in replying to any questions I had. I would definitely purchase from arm motor sports again.
Fitment was perfect and everything I needed to install properly was included. Product looks great and functions perfectly. Highly recommend.
The intake itself is in pretty good quality and shape. But I would recommend getting some after market inlets so it would fit much better.
