hehe, well the instructions themselves that come with the box are in 4 steps:
1. Remove the stock intake box.
2. Install SIMOTA's products on the inlet manifold
3. Fasten Bracket
4. Install Completed.
Kinda lame, and if you don't really know anything about cars, it might take you like maybe an hour or so max to figure everything out.
It's fairly easy though. Just take out the air passage to the battery, unscrew the sinch-tie that holds the tubing to the engine, as well as unscrew the air sensor. Pull up on the intake box (it's just clipped in on the bottom) and take it out of the car. Set the sri's bracket in first (trust me if you have big hands like mine), pop the sri in there, fastening the tubing back onto the engine, insert the tubing and the air sensor, and you are golden. It sounds complicated on paper, but after you do it once, it takes you like 15 minutes to do so no worries.
