Allowed me to delete the silencer in the airbox for my car.
Cheaply made product. Went in the trash!
I’m extremely pleased with my intake resonator delete plug from J-Form Designs. Communication was excellent from the start, and shipping was fast. He created a custom plug specifically for my 2025 B58 X5, and the fit was absolutely perfect. The quality and attention to detail really show. Great seller all around—highly recommend.
Good quality, I can hear more turbo spool out and inside the cabin, highly recommend 👌
Item fits BMW 2020 G30 540i if you have one of each plugs listed in main description. Ask seller about this as we found it out together! Seller was quick to help and send me one large to use on the top side of my intake. The port closer to the turbo is the smaller hole.
Awesome upgrade so that you always have easy access to the downpipe and turbo. Get rid of the ugly and useless intake resonator box.
Stock intake is good for up to 700hp. Don’t waste your money on aftermarket intakes and charge pipes until you have to.
