Coming in as a more than less last bolt on. I had ported my own and that got me by but now I wish I had got it sooner. When it's opened up it's super intense. The last couple K RPM is amazing. It didn't get any spin out of my new tires but a little adjustment on my exhaust fixed that problem. 90mm is not to big. I'd say if you have headers with high flow carts and a tune get this bad boy and pull a log or two. You won't regret it. You don't have to port your intake for it to open but I did. Almost always nails a good downshift and pulls so damn hard I love it.
Just need to be mindful when replacing the original to the upgraded 90mm.... it’s bigger so the fitting, rubber hose connecting throttle body to air intake may need to be heated to make easier to install ..
Try a hair blow dryer to heat the hose!!! Trust, it’ll make your life easier when installing
