Just wondering if there is any hidden Hp with a Stock Cls engine.?
Unplugging anything? Etc?? any one know.

 

yes remove the lower resonator on the intake and you'll probablly gain 3-4 bypass the coolant through the TB and when its hot maybe 1

 

where us the lower resinator on the intake, and how do I bypass the coolent through the TB? Thanks-

 

Headers and intake will give you another 30HP. It will cost $1500 though.

 

take out some excess weight

 

downsize your rims.......

 

he said free...do a search complete instruction are here on this site

 

if you want to clear your headlights, when you do the resonator mod, you could also clear your headlights. Or even change the bulbs. Taking off the front bumper is easy but bothersome in my opinion. May as well kill 2 birds with one stone. BTW the air filter change only cost about $30-40, may want to consider that. You can get a handful of HP from that.

 

Why would you remove the front bumper to take out the resonator???...Just pull it out from underneathe...

 

how would I pull it out from underneath???? what is it? A filter?

 

looks like a kidney

 

Do I need to cover anything up when I pull it off??
