I have used Sea Foam for years and love the product. Curious, i just cleaned out my throttle body and was wondering about the best place to inject the sea foam for the upper end cleaner. I have an 08 silverado with the 4.8L (25K miles) is there a better vacuum hose or is the brake booster still it?

Thanks

I find it hard to believe one product can work all of this magic? Can somebody explain to me how it works exactly?
