The ARM 7” FMIC measures 20 x 7 x 5.75 inches for a total of 805 cubic inches, almost DOUBLE the size of the OEM 535i intercooler and 180 cu in larger than our 5” FMIC. Combined with our Ultra-Dense fin packs, not only are you getting a substantially larger intercooler, but also one that utilizes its size efficiently for maximum cooling performance.
While testing the 7" FMIC for it's ability to cool the charged air, we found that IAT's increased only three degrees during a 3rd gear datalog. Considering our baseline test with the OEM intercooler resulted in a performance-robbing IAT increase of sixty degrees, the ARM 7" FMIC has 95% better cooling performance than the OEM 535i intercooler.
When testing the 7" FMIC on a Stage 2+ N54 335i we found it made an average of 10whp/10wtq over our 5" FMIC upgrade and 35whp/38wtq over the OEM intercooler!

Arm Motorsport had great and fast shipping Excellent customer service.
My overall experience was good shipping was fast haven't put parts on car yet but the parts seem like a good fit
Excellently made products. These guy's customer support is on point.
Had no issues with the intercooler or the included piping, but there was a fitment issue with the driver side intercooler mounting bracket. I added more brackets to make it work, and it works great! Hopefully Vargas doesn't send you 3 series outlets for your 5 series, like they did for me.
First time ever replacing an intercooler It was very easy and the fitment is on point Thought the upgraded lower charge pipe would rub against the PS pulley but it has enough clearance Elbow grease that thing and you’re golden IATs are pretty consistent, of course! I do not regret buying this kit whatsoever.
