Just installed my CAI Injens (no mechanical experience) small review

wipeoutlol · 11-01-2009, 07:16 PM

Hey all, first performance mod. Ordered my Injen intakes from Import DPS.. Fast shipping thanks to them..

This was my first time doing a performance mod on my car, although not as sophisticated as anything else. I did a short ram on my civic a while ago but that was nothing. I will say this can easily be done by someone without any mechanical experience.

First, taking off the bumper was pretty easy although timely thanks to the DIY write up...

Taking off the actual bumper sounded painful after all the bolts were taken off. there were 2 bolts that were silver the rest were black, I forgot where those 2 go specifically I couldve put em in the wrong place but im not sure. I just put them in the wheel well connecting the bumper.

Next time I'm going to put labels for groups of screws heh.

The only bitch of the whole intallation was removing the drivers side air resonator which took me about an hour heh. Couldnt get the screw driver to pop the clip. But I managed to do it from underneath after a long *** time..

Removing the stock intakes and the washer reservoir was easy as hell.

Putting in the actual Injen tubes required some shoving into place, and the filters themselves had to be pushed against some stuff to fit, but nothing too bad.

Putting the bumper back on was kind of strange, i snapped it back on but it seemed like the clips on the middle passenger side got damage or something cause it seems kind of loose, more of a gap there than there was before. And while bolting on the metal bracket that says (LH) or whatever, i heard a snap when screwing it in, not sure what I broke.

Also dropped 2 screws from my clumsiness...and being the genious that I am I forgot to hook up the power to the motor on the new washer reservoir as well as plugging in the black plug lol. So once I take off the bumper again to hook that up Ill find those loose screws my car has. I'll probably do it in a few thousand miles to clean the filters while Im at it.

All in all the install took me 6.5 hours. A lot of that time taking out drivers side resonator, and reading the instructions on my laptop.

The rubber tubes that hold the intake to the motor on the drivers side is a little awkward shaped since the intake tube is pushing out at it cause it doesnt PERFECTLY fit on the drivers side but its not that bad or noticeable.

The car sounds really loud with WIDE OPEN THROTTLE past 4k RPM and stock exhaust now. I really do notice a speed increase. Sorry no DYNO.

All in all very pleased with the intake, although its the only one I tried. Well worth the price and I would recommend it to a fellow G37 owner.

I could include pics if someone really wants them, but theyll just look the same as any other pic people have uploaded. I might upload the bumper pic in case people are curious.

I had battery disconnected for some hours, and I do notice a LOSS in MPG from 26-27mpg highway to 23-24 mpg highway. and about a ~2mpg loss on city driving. Not sure if its because ECU needs to learn to use it or not.

Anyways, I'll be contemplating which mod to hit up next in the meantime. A twin turbo would be a dream, way too expensive though

Good job, mods are always better when you do them yourself.

Get an exhaust next, you can install that yourself also.

^^^would highly recommend a lift though.

wipeoutlol · 11-01-2009, 08:42 PM

Yeah heard some great things about HFC, test pipes and exhausts... but also heard it robs some power from the intakes.

I would definitely have to find out how to get a lift.

Had anyone tried to pop out the fake vents for the Injen CAIs for maybe better gains?

denishot · 11-01-2009, 09:50 PM

don't install HFCs or test pipes by yourself please lol

TommyG37S · 11-01-2009, 11:52 PM

Yeah I totally love my Injens too, install overall wasn't too bad...I as well hated taking the bumper off...oh well gonna have to do it again in the future to clean'em. I am as well getting HFC 's soon but definitely gonna get as shop to do it after reading all the horror stories on here

That sucks you got to take the bumper off to clean those air filters!

That's the prob with a lot of the Cold Air intakes on the G. When you need to clean the filters. You will need to completely remove the CAI to do so. What a f'ing PITA!
