I'd go with JLT. I spoke with a guy at AM, I called asking about the Steeda. He said they had gotten better numbers with the JLT. Now, a business is about making money so when a guy at a business tries to sell you on a product that's two hundred fewer dollars, there has to be a reason.
I say also JLT because the front of the S&B filters they use is open and has a little witch's hat instead of a cap on it like you see on Airad, Roush, BBK, or C&L.
Of the four mentioned above, with the exception of BBK, the JLT tube is straighter.
