2003 clk 320

I have a clk 320 coupe with 40k miles. I am looking for some engine performance upgrades. I do not want to void the warranty and this is my first car, I was a SUV guy for awhile. I have seen a 4% percent hp/torque performance claim from an air filter upgrade, a start.

I would like to change the plugs and wires but, to be honest, intimidated by fussing with such a foreign, to me, engine. I comfortable with American motors but I do not want to screw up my warranty of my ride!

Any help would be great, thank you so much.

RE: 2003 clk 320

Get a powerchip at " ".com. I did it to my 430 and its way better and its undetectable to the dealers scopes and if they erase the program, it resets itself w/o you sending the ecu in. costs around $700-800 and youll get about 8-10hp but the car shifts different,responds way better. highly recommend!
I cant believe the air filter gave you anything though.
