About 2 weeks ago I decided to remove my mid-pipe w/ K&N cone filter. I was having problems starting the car every morning and my car was shifting horribly from 1st-2nd, especially from a dead stop. So when I installed my stock intake back on, in the days following I noticed that my max was shifting better than ever before. I was not getting that jerkiness through shifts. I also noticed that my car was starting without effort. With my intake, if my max was cold I would have to crank it at least twice to start.. Now it starts on the 1st crank. Also, my engine is so quiet, I didn't realize how annoyingly loud that filter was. Best thing I ever did to the max. It seems like my intake was sucking in to much air. Just thought I would share my experiences and improvements.

 

My car jerks and booms a little when shifting from 1-2nd ...also kinda gets stuck in between gears in overdrive in the city...is this what you mean? I did put a new filter in not too long ago too :-/ hmmmm

 

I mean like at a stop, when I got to accelerate from 1st to 2nd gear, it seemed like it would jerk or stick in gears. I thought it was my transmission acting up, but after returning it to stock. It shifts so smooth between 1st-2nd that I cannot even feel it.. A lot of people on the org have talked about the automatic transmission doing this, but I only had this problem with my intake.. It stopped after I put everything back to stock..

 

It's impossible for the engine to suck in too much air. That's what the throttle plate is for. You must've done something else in the process of removing your intake to resolve those issues. The intake itself wasn't the problem.

 

Mine has a jerk only when I go from 4th to 5th, it was more noticeable when I had a full CAI but I put the stock midpipe back on and it helped out, it is still happening though, changed my fuel filter this weekend and it still does it, just way less noticeable.

 

It could be your MAF going, and changing the intake just made it less jerky or not noticble.

 

so are you saying that only the filter was changed? or a full CAI?

 

i changed the K&N cone filter plus my mid-pipe back to stock.. My maf is a few months old. It's not going out.. I know what the problem was the filter was sucking in too much air, now it's getting the right amount, the way the car was made. Everything is running perfect..

 

The filter cannot suck in too much air. WTF are you talking about? Like i said before, the throttle plate controls how much air goes into the engine. Period.

 

ok, well it NOW I don't have that jerkyness between 1st-2nd.. I don't care how it got fixed but all I did was return to stock. I didn't F with anything else.. I would think that an intake allows more air into the throttle body, than the stock intake.. peace

 

i took my stillen pop charger off and hacked my stock airbox minus one resonator and its been running awsome. so smooth and quiet, tons more pick-up than before with the filter.
now i can pass 3k rpm and shift more smoothly without having that 'wound-out' noise.
dont think ill ever put that thing back on. it was seriously bogging my engine down and i wasnt getting any power, i didntthnk it would have such a huge drop from the stock filter. the stillen was clean btw
also took my 100lb sub box out and that makes a huge diffrence too
