I have a few questions about the Injen CAI for the '07 tC. I read numerous comparisons and decided on the Injen because it seemed to get the best reviews, so I went ahead and ordered the Injen. I am wondering how easy or how difficult it is to install.

My car knowledge is so-so, but probably lacking in the engine department. I have changed my wheels, installed my custom grilles, done some basic wiring, changed bulbs, etc. I haven't really touched the engine on my own yet, but am considering installing the CAI on my own. I am good when it comes to following instructions, so if the instructions are clear then it should be a breeze. I wondered if there are any specific tools required that I might need to borrow from a friend? I also heard that the bumper and front-left wheel need to be removed, but that should not be a problem.

Also, I understand the Injen intake can be installed in either a CAI or SRI configuration. For me, the two-part CAI setup is the only way to go. If anyone went with the short ram setup, can you tell me why? I don't see any advantage to SRI. The full CAI will be harder to install, but in my mind it is worth the extra work.

Thanks for any info. Also, if a tutorial exists on installing the Injen intake, that would be awesome. I saw a tutorial for the Weapon R, but that's a bit different.

 

here ya go.

You should have no problem at all. This is a very basic install. Just make sure that you leave yourself enough time. Whenever I rush I always seem to get frustrated and tend to make mistakes.

Luckily this system comes with step by step instructions. Make sure to let us know how the install went and how much faster your car is

 

Very basic for you, maybe, but it will be the most complicated thing I have attempted. ;)

That is a great thread, thanks for the link. Looks like most people are doing it on their own in under 2 hours. I'm definitely going to try the install when the parts arrive next week. I'll be sure to let you know what happens.

 

Its not difficult but a pain in the... I have the 06 and it tells you to remove the bumper and the wheel. I managed not to remove the bumper but scratched the cold pipe a bit. Just take your time...

 

Would it be easier if I do remove the bumper? I have now read all 10 pages of that thread, and I am left unsure about which method is better. It sounds like you can either remove the bumper and the wheel, or remove the wheel and loosen the fender. Removal of the bumper looks easy, so I wouldn't mind doing that if it would make life easier.

 

Well i tried to half fast it and ended up scratching it. I would recommend taking of the bumper but I thought it would be a pain in the butt so I winged it.

 

i just undid the bumper on that side and pulled it back just enough. i had a used intake so it was already scratched, lol. the second time i did one it made things a little easier but that extension pipe was still a _____, if i were to do it again i would just leave the bumper on. also, i still managed to scratch the pipe a bit even when i did take the bumper off but its in a spot you can't see anyway. good luck man.

 

It depends if you pay close attention to detail, but if you are worried about scratching up your intake try masking the tube with 3m blue painters tape during the install. When you are done just pull the tape off.

might help out

 

Have you seen how the CAI sits? That would be more of a headache to take it off after

 

no one answered your question to why people use SRI i think, so people use SRI to avoid hydrolocking and i heard that theSRI compared to CAI is louder in sound. But since you live in SoCAL then stick with CAI, i dont think you gotta worry about hydrolocking there. And if you dont know what that means then its the intake sucking up water then going into the engine then engine shuts off......it can be somewhat prevented with a AEM bypass valve that fits in the Injen CAI also but like i said since you live in SoCAL forget about that stick with CAI. I myself am using the Injen CAI w/o bypass valve and the install is MUCH easier if you take the bumper off, don't do a mickey mouse job. You can resell the intake better w/o it having any scratches if you ever decide to do that in the future

 

oh and one more thing if you haven't already, order Dr. Isotope's CAI fender mount for like $18 bucks or something. It will prevent the CAI from rattling and mount breaking

 

Thanks for the good advice. I had no idea about the fender mount or the potential for fender damage, but a quick bit more research has shown me this is definitely worth the money. I just order my fender mount, and the intake actually arrived today (I expected it next week). I will be doing the install once the fender mount arrives.

 

thank you for the info
