Customer Reviews
Got my new intake, it's good!
So I finally got around to grabbing that VW MK6 GTI Intake from here. Instal was pretty easy, like 30 mins tops. It definitely makes the turbo noises louder, which is kinda fun. Didn't notice a huge power jump but the car feels a little more peppy. The box arrived in good shape too. No complaints really, it was a smooth transaction.
Reliable as always, great intercooler
This isn't my first order from ARM, and they keep delivering. I picked up the Audi RS3 Intercooler this time. Just like my previous purchases, the quality is top-notch. It installed without any drama, exactly as described. I've always appreciated their consistent product quality and how everything just fits right, no surprises. Shipping was standard, about five days to get to my door, which is what I've come to expect. This is why I keep coming back for my Audi parts; never had an issue.
Quick shipping, perfect fit
Got the BMW N55 Downpipes. They shipped fast. Install was straightforward. Happy with the quality and fitment. Definitely recommend.
Good Intercooler, shipping a bit slow
I bought the BMW N54 Intercooler Upgrade a few weeks ago. The part itself seems well-made and the fitment was pretty good on my E90. I noticed a decent improvement in intake temps, especially after a few pulls. My main gripe was the shipping time, it took 7 days to reach me in Arizona, which felt a bit long compared to other places I order from. Customer service was responsive when I inquired about the tracking, so that was a plus. Overall, it's a solid product for the price, but they could probably speed up their logistics a bit.

Share tips, ask questions & help fellow shoppers save more
Hey, thinking about grabbing a downpipe for my N54. How long does shipping usually take to, like, California? Don't wanna wait forever.
Does ARM Motorsports do that financing stuff, like Affirm or Klarna? Easier on the wallet for a big purchase.
