It's pretty easy to split it between the two sides. An S8 would obviously be more difficult at it has two air boxes. It did stumble a bit when I drove it afterwords and it set some codes for misfires on all cylinders. But after that it ran great. In fact my butt dyno felt like it ran better. I know that's not an accurate measurement technique but it really does feel like it runs better. If it helps keep the carbon off my valves and the gunk buildup out of my intake then it's worth the $8 and 20 minutes it took to do it.
