So far, the best option I've seen is X's intake. Exerybody has high hopes about the Password JDM carbon fiber "lung" that's supposed to come out, but that's going to be over $300, then you still have to buy their battery relocation kit (and battery) to get the intake to fit. In the end you have a $500+ intake. Or you can get X's for $300, and have proven HP, and TQ gains, as well as regaining power in the lower rpm range (which I lack due to my Fujita SRI). Hope this helps.
