Fits great no problem installing. When you spend the money right everything fits right. The sound of this bov is way different from hks or any other. Really like the sound and performance and quality of this GFB.
I had high expectations for this bov as I have been wanting it for a few years now. Go Fast Bits blew this one out of the water to say the least. Install was a breeze, no gasket for intercooler needed as it comes with an o-ring, it looks absolutely stunning and adjustments on the fly couldn't have been made any easier. I am beyond impressed with this and 10/10 recommend.
If you are looking for that old school blow off sound this is the way to go without breaking the bank. Install was easy, very detailed instructions. Recommend having a 2nd person for making final adjustments to the GFB Respons Hybrid BOV. If you are not very skilled in mechanics install will still be fairly easy, be sure to read through the instructions before beginning the install. Don't get discouraged by how many steps there are to the install. Definitely worth the price with how much quality control goes into this product.
Great craftsmanship and design. Easy to install make sure you order a replacement gasket, in case the oem gasket is worn. It is best practice to replace old gaskets when working on something which allows you access to the older gasket. This is very easy to use and adjust. Make sure you follow instructions. Adjust set screw one turn at a time some half turns either plus or minus depending on where your level needs to go in order to get the proper throttle response. Take several test drives and adjust each time, until you reach the correct setting. I am very pleased with my purchase. I do recommend this product. It is direct fit.
This blow off vale is pretty nice it look and sounds really good

A: You can not tune for a blow off valve, so not tuning would be required. The adjustment screw is to adjust the amount of recirculation or venting to atmosphere, which effects the noise.
