Today I installed the K&N drop in and I did not yet removed anything else. I may say that the car is acting a bit better and is a little bit quieter now than before (saw this at WOT). For those who might ask, yes, I kept the lid on.
There is still the little "shake" while the car is "idle-ing" but not as much as it was before. As far as I read here, it seems that if I do the snorkel delete, the "shaking" would be 99.999% gone and I'll have some sound increase. I'll test it for two tanks without the snorkel delete, I will then do the snorkel delete and post my thoughts about.
