This works with both the stock air box, and aftermarket air intakes!

If you have a 2012-2018+ Fiat 500 1.4 Turbo, 2013-2016 Dart 1.4L, or a 2015-2018 Renegade 1.4L and want a blow off valve noise instead of a whisper quiet engine, this is for you!

We've designed a diverter plate that goes in between the factory diverter and the turbo. With this piece, when you shift, or release the gas you'll hear a audible whish noise!

In most cases, whenever you wanted to install a blow off valve you'd need to buy a $250 blow off valve and then buy a mounting kit for a total of $350-$450. With this simple bolt on piece, you can keep your stock diverter, and have just as much fun for a lot less!


  • Easy installation, takes about 5-10 minutes with a single allen key.
  • Polished aluminum construction.
  • Great blow off valve sound in minutes without spending a lot of money!

Below is a video of the Forge plate installed on our Dart 1.4L Turbo. Our MPx plate is very similar and has the same sound and look for a lower price!!!

Note: The OEM intake system does not provide enough clearance for both the Go Fast Bits Diverter Valve AND the Forge or MPx Blow Off Plate to be stacked together. If you intend to use both of these products, you must first purchase an aftermarket intake to create enough space to do so.

      We have not directly compared the two, but it should be very similar. The only difference between the two is the Forge has two sides of ports, whereas the MPx has three sides of ports.

      I got to say that it almost sounds the same. Here is a sample of the MPX Blow Off Plate:

    Do you know if this will void my warranty on my jeep renegade?

      This is a very simple piece, it does not change boost levels, it doesnt alter fuel trims, etc. There is no reason any dealership should ever give you any problems with this. If you are still concerned, it can be removed in 15 minutes before going to the dealership.

      Definitely. You can install the GFB by itself, or with the MPx plate, or with the Forge plate, etc. If you use this with a noise plate, you'll need longer bolts though. You can get those separately from us, or just buy the GFB plus plate package that comes with longer bolts.

      Forge- has two air release holes
      MPx- has three air release holes

      That's the only difference other than price.

    Would the blow off be louder with the plate and cai then just a cai ?

      With an aluminum intake and no blow off plate, you'll have some sound that reverberates through the intake tube and makes noise. You'll be able to hear it in the car, but it will not be as clear, or as noticeable on the outside of the car as if you have a blow off plate. This is because the blow off plate releases air from the turbo into the engine bay directly so its louder, and more crisp sounding.

      This is one plate fits many 1.4 Turbo cars. Its exactly the same between Jeep/Dodge/Fiat We have a pull down menu to select which car you have so we can better understand which platforms are moving which parts.
