Feeling sluggish?

I've been feeling more and more recently as if my car is becoming more slugish. When in D1 the throttle response is off, it doesnt seem to pull as hard either. I also noticed that when accelerating for some reason the rpms seem to lag around 1500-3000 rpm then start to rise smoothly. What gives?

I'm due for an oil change in about 4k miles, could that be it? And a bms powerbox is not the answer lol. Should changing my air filter and getting rid of the carbon filter help?

My car gets sluggish sometimes. I simply perform the automatic transmission reset and the driving improves.

No I dont, just go to K&N's website and enter your car info.. im sure you can figure that out.

The filter works great, no issues. way better then stock you will notice it.

My stock air box is modified, I have a metal tube for it, and secondary inlet of air from the brake duct. sounds good, works good, is good

I will post some pics for you to check it out, This one is a little more advanced then the others that were done, once I get some time I will take some pics for you.

To start I would just get the K&N and do the carbon, then go from there if you feel the need to

if its only been 4k since your last oil change i'd say you probably just have to reset the car.

Products such as the aFe intake paired with the BMS PBX will increase your throttle response!
