1000 more seat horse power. Just buy it
Trims will be way off with the green filter. How would I know thoughYou do not need a tune to use the green filter. My car is stock except airaid with green filter and never had an issue for over 5 years. But if you are planning on those other mods you will obviously need it tuned so get the green filter at the same time you buy those other mods and have it tuned all together. Btw it is definitely worth it and many others think so as well. Just a pain to get it in there as its a tight fit
