Product Description

It appears that you’re not the only one with excellent taste in premium automotive components! Unfortunately, BLACK Alternator Covers are temporarily out of stock. They should be available again soon. Please contact customer service via phone (612-379-0000) or email for details!


Tired of being teased for your corroded alternator and boring engine bay? Step your Alternator Cover game up; GrimmSpeed has just what you need. This cover mounts securely in place of your plastic factory cover and its asymmetric design is intended to compliment the GrimmSpeed Tool Tray Radiator Shroud perfectly. Available in brushed stainless steel, as well as our three standard texture DuPont™ powdercoat finishes, there’s an option for everybody. 

Quick Specs

  • Laser Cut Venting - provides plenty of cooling for your alternator
  • Machined Aluminum Mounts - anodized black for a sleek look and corrosion resistance
  • Heavy Duty DuPont Powdercoat - ensures a durable finish and resists discoloration
  • Slotted Mounting Features - flexability for tweaked factory brackets
  • Drive-by-Cable Dimples - hidden on the bottom face, dimples locate holes for cable mounts where needed

Once again utilizing our in-house FARO Arm along with 3D CAD software, we were able to map the location of not only the mounting points, but also the smaller, critical components in different model years. A belt cover designed without these in mind can wear through hoses or wiring and worse yet, may contact your accessory belts or pulley, causing serious damage. What this means for you is that the best fitting Alternator Cover on the market is here at last. It’s what you can expect from GrimmSpeed, and it’s what you’ll get with this kit. 

GrimmSpeed Alternator Cover - FARO Arm 

Our Alternator Cover is precision laser cut from locally-sourced material and the drive-by-cable dimples are punched before its CNC bent for a perfect fit. Aluminum covers receive a durable DuPont powdercoat in a textured red, black or silver, while the stainless steel covers receive a protective film to prevent scratches in both manufacturing and shipping. Mounting of the cover is facilitated by machined aluminum supports. Following the machining process, these supports are black anodized for a clean look and corrosion resistance. This is particularly important in an environment like your engine bay. Stainless Steel hardware finishes the look and keeps everything planted firmly.

  1. It fits and looks great!

    Posted by Ben Muro

    I had been considering getting a non-OEM alternator cover for quite some time and finally gave in and bought the Grimmspeed one. It came within a week and was everything I thought it would be. The install took roughly 15 minutes (one of the bolts from my snapped OEM cover was very tight so it took extra time), and watching a video helped make the install quick and easy. My engine bay looks fantastic with the red one, and I find as a bonus that when I work on my car, I like to set tools on the cover because it is relatively large. Couldn't be happier with the product, and would definitely recommend it to anyone willing to spend the money.

  2. awesome

    Bought this a rocky mountain subiefest 2016. Awesome addition to the engine bay.

  3. GS Alternator Cover

    Posted by Rick K

    I went with black. Fitment is spot on '17 STI. Would fit my LGT as well. The GS cover looks great and doesn't interfere with the dipstick or oil cap. I really like that the logo is cut instead of printed on the cover. Finish is durable and perfect for the engine compartment. Install was a breeze. Pleased with the quality and with the purchase.

  4. Amazing!

    Posted by Chris

    I have the black alternator cover and it looks awesome!Fits very nice and it compliments the rest of the engine bay. Must have if you want to liven up the engine bay.

  5. So fresh and so clean (clean, clean)

    Posted by Kentrik

    I picked up the stainless one.....It's shiny. It's pretty. It's also a good way to keep those belts covered.

    The install process was fairly easy, but with my giant sausage fingers, it was a little rough making sure the nut sits in place to tighten the one side. Still, totally worth it for both the protection and the bling factor.

    One thing I would advise - if you are drive-by-cable and not drive-by-wire, make sure that you still route the cables OVER this - when trapped underneath, your spinning belts can eat into the cable covers, and that's enough to ruin anyone's day.

  6. awesome
