Installing an Injen Intake in a Gen2 V-6 (+ video)

I just got this today. I was so excited that I installed in while still wearing suit pants and dress shirt. (I'm sure the stains will come out.)
Here's the intake kit: Injen Part # IS2032(P) - Ignore the listings that say 2003 Camry but don't list 2004 Solara. Injen can't list 2004 due to CARB issues with the OE carbon filter.
1) Remove the three bolts holding down the cold air intake to the radiator support. (Set them aside along with the upper portion of the intake. We will reinstall in later.) Disconnect the negative terminal on the battery. (Injen claims this helps the ECU learn the new intake.)
2) Unbolt the upper half of the airbox. (As if you were going to change the filter.) Loosen the clamp closest to the airbox. Detach the MAF Sensor but leave it screwed to the box. (To keep it from getting damaged during your installation.) Disconnect the vacuum lines to the front side of the box. Coil them up and plug the tubes. Use a plastic zip tie to secure it out of the way. I hid them between the battery and the radiator support.
There are two small vacuum lines on the left side of the box. Disconnect them and place them aside. (You will need to reinstall them onto the new intake.) Wiggle the upper half of the intake box loose and pull it off the intake hose you already loosened.
3) Remove the airfilter element. Throw it in the pile of useless junk. Unless it's a K&N or TRD filter, then sell it on SolaraGuy.org.
There are three bolts at the bottom of the intake box. Unbolt them. There are two wire harnesses attached to the intake box. Cut them free. Secure the harnesses with a zip tie. (Remember to attach the tie to something on the engine and not the body or master cylinder. Otherwise you'll cause damage as the engine moves.) You should be able to remove the lower intake box. (Leave the lower cold air intake duct. You can always use cold air blowing directly on your new filter.)
4) Remove the EGR tube from the OE intake tube hanging off your throttle body housing. (Set aside). Loosen the clamp nearest the throttle body. Remove the hose / resonance box off the throttle body housing. (Place in foremention pile.)
5) Attach the damper bolt to the factory intake box bracket behind the battery. (The bolt hole closest to the engine.) Remove the washer and nut. (Set aside) Slide the Injen Hose over the throttle body. Slide the two loose clamps onto the intake hose. (I installed the tightening screws on the left facing up. So you can tighten them without working around the strut bar.) Don't tighten them yet.
6) Install the 5/8" plug Injen supplied onto the short stub tube of new intake. Insert the intake tube into the new filter and clamp. Tighten down. (Don't worry about orientation of the Injen logo on the end of the filter. No one will see it behind the battery.) Insert the intake & filter into the hose on the throttle body. Slide the bracket onto the damper bolt. Check to make sure nothing is hitting the body. Tighten down the intake hose clamps, damper bolt washer and nut, install the three hoses you set aside earlier. (Two 4mm vacuum lines and one 5/8" EGR hose.) Remove the MAF fromthe factory box. (Held down by two phillips screws.) Install into the new intake. Reattach the MAF harness and reconnect the battery. Reinstall the factory upper cold air intake duct to the radiator support. This will supply fresh air to the new intake versus the hot air coming off the manifold and converter.
Double check all the fittings and clamps. Now go have fun. It will take you less time to install it than you took to read all this.
As for the "butt dyno"; the induction acoustics are great. I had to hit wide open throttle while going through a tunnel. Very nice. However, I don't notice any significant performance gains. Just smiles.
For the real gains, I'm confident the CP-e intake kit is the way to go. (Use the search engine for those threads.)
Props to Patricia at Overboost.com for working directly with Injen to get the part to me quickly.

That was a very cool present. Pass along a congrats on the graduation. Atleast I'll know next time when I see smiley posts.
