1. Airaid MIT and replacement filter. $175
2. VaraRam Velocity Stack. $ 40
3. Granatelli MAS. (for cold-air) $270

Installed upgrades in this order. I noticed a small performance gain after adding the first 2. Just added the Granatelli a few days ago, it made a HUGE difference at all speeds! (Drove it to and from work several days and went on a 200 mile fishing trip to Freeport / Surfside.)

Well worth the $485 investment!
