Okay, So yesterday I did the airbox mod with just a generic oiled filter. I disconnected the battery, let the car idle and then test drove it.

First gear was good, but second gear seems to lag quite a bit more. It seems like it takes longer for it to get to higher RPM's. I love the sound and do NOT want to take it off. But i miss my speed.

my cobalt is my life and i just want it to be fast!

Help me!

 

Seems like your car is bogging, and hesitating, the oil could have gunked up your maf.

 

yeah it almost seems like when it hits 3k rpm it goes down a little then goes back up

 

lol i just installed my gmpp intake yesterday and i have the same problem. it seems it is lagging little bit. but at higher gears it opens up and it sounds great. i didnt know it was going to be that loud when u step on it. i dont need a muffler any more its loud enough.

 

It is the air filter. Not everyone will have this problem, but some come oiled more than others. That oil gets the maf dirty and then you have wrong airflow readings. Your car may even throw Rich Codes. P0171

 

P0171 is a lean code... but yeah. I gotta ditch my oiled filter and snag a AEM dryflow soon.

 

"generic oiled filter"


Got what you paid for.

 

I will be ordering a dryflow soon, I just couldnt wait for the scream!

 

yeah you can, rev it up to 5g, then drop the clutch, and you have more than a scream

 

lmao no seriously i did lol

 

Quite possibly true my friend. This is my 2nd Spectre filter... ran the 1st one for 10,000 miles without a single problem. Ran this one for 1000 miles before the code finally kicked. Just kinda wierd.

 

Any one of you know what site you can order one of the AEM dry flow filters from?

 

uh...www.aem.com...

 

American etching and manufacturing?

 

i have a ingen intake and havent had not one code or problem in over 2 years

 

I am actually suprised that with at least one thread a day of someone with this same problem, people are still going out and buying oiled filters instead of the AEM dryflow. I'm not saying that you are guaranteed a problem with the oil filter, and for those of you that have them without any problems that's cool. But, if someone is planning on doing this in the future you may as well avoid a "potential problem" and just buy the dryflow.
