Reading their instructions is a good idea...the IAT sensor and grommet can sometimes be fun to remove/reinstall...they can be tight. 
Installing the Lid
It's pretty easy. The hardest part was trasferring the EGR sensor. I was to the point the rubber grommet was going to rip, so I ended up cutting it out of the old lid. I tried to grease the grommet and insert it into the new lid, but it wouldn't budge. I used my dremmel and did a light port job on the new lid, and slid it in.
the most difficult part is the IAT sensor, they can be a bitch so prepare to work with it a little bit, just be careful not to damage it, they are close to $30 bucks to replace, and after the install make sure it seals, a good thing to do is start the car up after you install it, and use a can of wd-40, or ether, and spray around the seal of the airbox, if your idle doesnt change your good to go!

Yea, thank god my SLP induction package finnaly came in. I installed it yesterday... never had any car mechanic experience or anything. It was a breeze... just read the paper instructions that come with it lol. The IAT wasn't difficult for me... but when i first installed the lid i wondered wat the whole in the neck was.. lol stupid me i forgot to take it off my stock lid and put onto my SLP lid. It was real easy taking it out... i prob. didn't do the smartest thing but at the time i didn't know it was so sensitive... i grabbed some plyers, clamped it on the edges and just pulled it out... easy... then installed the lid. The ram air was the most difficult... cutting and getting it to fit right... it was an overall fun day... i'd do it again!
