My first, but hopefully there will be many many more.

 

how hard was it to go cold air? and did you try it with just short ram?

 

haven't done it yet, (i took off the resinator and will get the K&N Drop in, pretty much the same thing, but for $40 instead of $200) but i can't magine it being that hard... airbox is a piece of cake to take off, resonator is like 2 clips, just take the wheel off and the fenderliner...

 

I didn't try it with just short ram.

It wasn't that bad to install, Injen directions recommended removal of the front, which we did. It took a lil over an hour for everything.

 

Looks really good

 

Looks awesome, now lets lose that huge plastic cover on the engine

 

Can it be taken off without affecting anything?

 

\

yes. I left mine on though...the Ecotec is not a pretty engine.

 

Yes but if you get mad wheelhop kiss your oil cap goodbuy. Luckly my engine cover was still on at the track which is what my oil cap was screwed into otherwise i would have none.

 

Rush...How was the performance increase?

I'm looking to do the same thing with my 2.4L, but I don't know if its worth it.

 

Well, it was just installed yesterday and to be honest I did not "feel" much difference in it. The car itself, only has 2200 miles, so maybe I just didn't notice a difference due to not owning the car very long. However, when I hit about 3.5 rpms there is a huge sound difference. But, I haven't driven it very hard, or much, since I have put it on there, so maybe I just need to give it some more testing.

 

nice job..looks good

 

Looks great. You made the right choice with the Injen.

 

Take off the oil cap. Remove the engine cover. Remove the oil cap riser (its tight, but a simple quarter turn is all it needs). Put the oil cap back on directly to the valve cover.

Then later, get your valve cover polished up to match the pretty new Injen. Maybe get the MPX billet oil cap to match too. Like this:

 

i have the same setup and i noticed a little pick up and when the exhaust was added it really helped out the top end....definately more pull now....nothing amazing but it is there

 

I hate how my injen intake isn't all one size like the cobalt one

 

actually, i was afraid of that too. but when i took off the riser, the thread is exactly the same, with the same size o-ring too. so it makes no difference if its just the oil cap or if its on the riser, it shouldnt fall off. Itll only fall off if its not put on properly

 

the only thing it changes to remove the ugly plastic is that you hear your engine sound better.

and halfcent, us 2,4 don't have a pretty engine top like that

 

hey how did you get your valve cover to look like that. i worked on mine for like three hours one night and it just looke ok. Any advice would be cool.

 

I never even realized that oil cap riser could be removed, thanks for the idea Halfcent. I pretty much had to butcher mine to get it off, but it looks much better now. And yeah the 2.4L isn't nearly as nice looking as the 2.2L. We're the freakish cousin who lives under the stairs and eats buckets of fish heads

 

There are write-ups in the how to section about polishing aluminum. You use Rogue. It's like a polishing compound for metals. Take the part you want to polish and get in on a bench. For the valve cover, that means taking in off the engine. Start with wheel brushes on a drill and get the whole part buffed. Use a Dremel in the tight corners. Then go to the Rogue. You can buy it at Home Depot in the tool department. Grits of black, red, and white in that order. Use a different buffer wheel for each. Then a little mothers aluminum polish and your golden. It's very time consuming, don't rush.

 

Does anyone have proof of this? I mean a K&N drop-in doing the same as a CAI? I have the K&N drop-in and yea it did give my engine a little pick me up but nothing special. Does anyone have any dyno sheets of what each makes?

later

 

an air filter will only do so much. The only reason you get a horsepower gain is because the computer realizes there is more air being taken in, thus, it has to pump out more fuel to keep the fuel/air mixture just right... thats your power gain right there.

 

I sell some stuff that polishes any kind of metal, I even took the paint off a pepsi can with it, it's strong stuff and it works great, If you want more info, pm me
