OK before talking intakes though, and since I can't see your model, does your car have a silencer? If so maybe a silencer delete will get you the sound you like without much trouble and with zero cost. Something to consider. You could get the result you want for free maybe.
So, about intakes. There are two types: ones that require a new map and ones that don't. I like neither. The ones that don't require a new map don't seem like they make a difference worth their expense, since after all they don't make a difference requiring a new map. The ones that do require a new map make a difference large enough to require remapping the car, so they're not worth the expense. Intakes can't win with me.
Add to that the filter issue - the stock filter is excellent and the stock intake is great at doing its most important job: providing clean air. High flow filters that clean better would be great. So would world peace. The stock setup yields low dirt levels in the motor, when measured in terms of Si in the oil. Miracle filters are underwhelming.
Now, the SPT intake apparently does not require a map. It does affect your warranty, but it comes with its own warranty terms. I believe other makers have also claimed theirs do not require a map - have you contacted Cobb for example?
