N54 Full Bolt on kit
Create a custom FBO Kit for your N54. Customize your full bolt on kit exactly how you want it for your build. This is the exact kit used in our N54 335xi build.
5" FMIC
An ARM FMIC upgrade is one of the best modifications for your 335i because not only does it yield an average of 25whp and 27wtq but it does so consistently. "How?" you may ask. When you increase power with a tune for example, you are increasing boost pressure and ultimately heat in the engine. When the ECU (DME) detects too much heat, it will actually reduce timing and limit the amount of power the engine can produce in order to avoid damage. What an ARM intercooler upgrade does for your 335i is keep the intake air temperature in the ECU's "safe zone", allowing it to maximize all the modifications you have on your car.
7" FMIC
At 805 cubic inches the ARM Motorsports 7” FMIC provides a significant increase in cooling efficiency over the 5" FMIC and the perfect intercooler upgrade for the N54 and N55 powered E90 335i maxing out the stock turbos or running a turbo upgrade. With almost a 30% increase in size over our 5" intercooler upgrade, our 7" FMIC a respectable step up in overall volume for handling higher boost applications where the IAT's can rise quickly.
1K FMIC
The foundation of the ARM 1K FMIC is it's massive core with a volume of 1,155cu in. Measuring in at 20"x11"x7.5" it is 270% bigger than the stock intercooler and one of the largest FMIC's available for the E-Series BMW.
Size does matter, but it's not the whole story. Which is why the ARM 1K FMIC utilizes an ultra-dense fin pack of 20 fins per inch to maximize the volume of it's huge core.
Combine the over-sized core with the ultra-dense fin packs of the 1K FMIC and you have one of the best performing intercoolers available for the E-Series BMW. Below is a datalog from our project 335xi equipped with upgraded turbos, supporting modifications, and our ARM 1K FMIC. During 3rd gear datalogs we were seeing only 5 degree increases in IAT's from the beginning of the run to the end, the starting IAT being 59 degrees Fahrenheit, and still an icy cool 64 degrees at the finish.
RWD/AWD DOWNPIPES
Take your N54-powered BMW 335i to the next level with ARM Motorsports' 3" catless downpipes.
The ARM N54 catless downpipes eliminate the restrictive OEM converters on the stock downpipes allowing the exhaust to flow more freely, increasing power and torque. Because higher boost levels generate more heat, the ARM catless downpipes allows your 335i to run boost settings of Stage 2 tunes and beyond.
N54 CHARGE PIPES
Why do you need to upgrade the N54 charge pipe for your 335i? The OEM BMW charge pipe is a ticking time bomb for any N54 335i running higher than stock boost. Its plastic design will adequately hold the boost on stock settings, but on tuned cars it is prone to bursting. In addition, the OEM diverter valves are another component not designed for high-boost and can leak boost, limiting the power your 335i can put down. Don't wait until yours breaks to upgrade this critical component of your N54!
N54 RELOCATED INLETS
The ARM Motorsports N54 Inlets are the ultimate relocated inlet system for your N54. Relocating the inlets on your N54 with the ARM Inlets increase the power and torque of your N54 up to 60whp/60wtq. Expect improved turbo spool, faster peak boost, and more volume from the turbochargers on your N54. If you're looking to max out your stock or upgraded twin turbochargers these are a must!
N54 DUAL CONE INTAKE
The ARM Motorsports N54 Dual Cone Intake (DCI) allows you to easily add up to 20whp to your N54 335i by replacing the bulky OEM N54 intake with two open, high-flow dry media filters.
INLET ADAPTERS
The ARM N54 Inlet Adapters give you the ability to use 2" N54 Inlets on your stock N54 turbos. The ARM N54 Inlet Adapters are the perfect solution if you want to upgrade your inlets while running the OEM N54 turbos, but are planning on installing upgraded turbos in the future. This will save you the expense of having to purchase two separate sets of inlets, one for the stock turbos and one for the upgraded turbos.
FMIC HOSE UPGRADE
The ARM Motorsports' FMIC Hose Upgrade is designed to work seamlessly with the ARM 5"/7" FMIC and N54/N55 Charge Pipe upgrades to eliminate any restriction from the OEM connections. The ARM Motorsports' FMIC Hose Upgrade replaces the short hose from the turbo outlet pipe to the intercooler on the hot side, and the longer hose from the intercooler to the charge pipe on the cold side. With it's extra-large 3 in inside diameter, the ARM intercooler hoses are 50% larger than the OEM intercooler hoses, the largest intercooler hose upgrade available for the E8X and E9X chassis.
N54 TURBO OUTLETS
The ARM N54 Turbo Outlets increase power on your N54 equipped BMW by improving airflow post-turbo. This section of piping is enlarged on the ARM N54 Outlets to 2", and increase of 100% over the stock outlet size of 1". This section of piping is critical as it is the first component of the charge-air system.
