Hey anyone know of the difference between the power gains with the Blitz LM kit vs. the Sonic Power kit? What does this new Sonic Powerkit sound like? It states it whistles when it sucks in air....

 

From what I've understood, the sonic powerkit has two different size intake pipes that are overlapped. When air passes through each pipe, they resonate sound freqencies. With the combined frequencies from each pipe, you get sound waves that actually help your engine combustion. They are claiming a small increase over a normal intake. Try it out and tell us about it.
