Modified an aftermarket system I was unhappy with in order to retrofit a standard silicone coupler and this stack. Depending on my mood, I’ll interchange between a cone filter and just a filter sleeve depending on how much ffssssss-psssssssstttt I wanna hear. Throttle response seems greatly improved and more linear. Gear changes and heel-toe downshifting are now somehow smooth as butter. I’m a big fan of a stack and I’ll always be a firm believer that they certainly help increase intake velocity, even if there’s boost. It’s a simple yet effective device.
