If you want to take it one step further,take them out of the box and let them sit in the sun for a few hours first.

Ohok sounds like a good idea lolz.
That wouldn't dry out the oil and stuff up the filter right??

Nope , just enough to remove the excess.As the previous poster stated,the big problem comes after the 1st cleaning when people have a tendency to "over-oil" or "marinate" the filters,drop them in and rev the $hiat out of the motor and draw the oil on to the MAF.

Here is my story. I've read in some other thread about charcoal delete and K&N drop in. Got very excited about this easy mod. Ordered K&N, installed it and in about 20 minutes of driving got CEL. Cleared CEL, installed just stock filter with NO CHARCOAL. Worked for a couple of days and then CEL again. Cleared, installed all back on. No CEL so far. In every CEL case it was running lean. So, I am not playing this game anymore. Not worth risking reliability of the whole engine.

I am not sure. I've had K&N filters on all my previous cars without any CEL. Jetta MK4 and Audi A3. And this guys tend to throw CEL very easily.
I don't feel very comfortable driving with engine running lean hoping that it will adopt to it magically.
I also don't feel any power increase, in fact i feel like loss of torque on low end.

I'm a noob with working in the C63's engine bay. What exactly should be removed? Can someone post a DIY for us newbies?
Thanks in advance.
Thanks in advance.
Very noob question....
Tried to look at where to plug the 2 filters in, and not too sure.
Don't wanna start taking bits and pieces off unless I kno exactly where it is and what to do.
So here's the engine:
Am i meant to take these covers off??:
If someone's a pro here, how many screw thingys am i meant to be taking off? (so I don't go off taking too many off!!)
I'm assuming I take the 3 that is visible off, but do I hafta undo anything else?? (ie, the silver thing to the right of the red handle)
Thanks for any help!!

So - i had the question on how much hp / tq would a k&n drop in give - well here is some data - couldnt tell you if its accurate or not.
ac was on low the whole time and the pulls were done on a mustang dyno.
The numbers are a bit hard to read but...
stock
HP-383
TQ-380
K&N
HP-387
TQ-382
take it for what you will - and let me know if you have any questions.

It's not uncommon to see a difference of 1% on back-to-back pulls with no changes.
