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!
Fast shipping great product sponsor me :P
So, I’ll say this to start: if you’re new to this, this is a very involved job. I went into it pretty blithely thinking it’d take a few hours at most. Maybe if you’re competent, but this took the better part of the weekend for me. Once I figured it out though it was spectacularly easy and relatively painless. The quality of everything is excellent. I also purchased and installed the 3” down pipe which I am VERY pleased with. Waiting on the BOV line adapter before I really run everything hard. Also, ARM’s support team is pretty much unrivaled. Super patient and kind. Zero complaints. Just wish they had more products for the e60–I’d do my whole build with ARM parts!
