New intake, looses power 4500k rpm please help

Hey guys,
So I am new to the forum as well as to the wrx community. I am an owner of a 2012 wrx sedan pearl white! So far my only mods is a Cobb intake and rally armor flaps! My tuner and invidia exhaust is on there way but I got alittle ahead of my self and purchased the intake. Install was easy and I love the sound of this intake! Although it sort of created a problem. Around 4500rpm the car seems to shutter and looses power then kicks back in. It only seems to be in 2nd and 3rd gear pulls a tiny but in 4th as well. On my shops evo we had a similar problem, then we gapped the plugs and it went away! Is this the same problem or do I need to install the tune and see if that fixes it? Thank you guys so much for the input! Glad to be a subie owner again!

pretty sure you need a tune for your intake. that is most likely the problem.

The intake will cause you to run lean, either stay off of it until you get the new tune, or preferably, put the stock intake on until you get the tune. My guess is that the intake is causing you to run too lean, and your timing is being retarded because of it.

Thank you guys, it comes in Tuesday so hopefully that will fix it. What tune will I have to apply? Since I'm not doing a down pipe just yet?

Running an intake on an untuned car can cause detonation of your motor. It's really hard to feel bad for people like this. Lol

My first thing I bought was Accessport V3 because of how important it is to have. Should be everyones first purchase in my opinion.

Yeah with these cars as well as other turbo cars like the Evo/Ralliart you can't touch the intake system without a tune. You can do some damage. Let us know if the tune fixes your problems. If not there may be other problems now.

Not to beat a dead horse but that exactly confirms the need for a tune, the factory tune is nice and rich at the bottom and progressively leans out up top, The OEM tune is not just under powered but it can also be rather dangerous for the engine under "spirited" driving. Adding more airflow to the system can cause some serious problems. hopefully your AP takes care of the problem and no harm no foul.
@subawolfe , Its Tuesday, hows she run with the tune?

Sweet man we got her all hooked up and it runs and sounds amazing! I'm pleased to say the jerk at 4500 is gone.

Good to hear it, When you have time put down a few logs and send them to cobb, then post them up. The guys here are great with feedback.
