REPLACEMENT SPRK PLUGS

I need to replace my spark plugs. But with so many out there I am not sure which ones to buy. My engine has some after market modifications(AEM brute force intake, Helix power tower throttle body spacer, JET MAF sensor, and a magna flow Xpipe with true duals). I dont know if I should go with a shorter plug because the air mixture has been altered or stay with factory size, also the motor does not have a distributor cap as such, I believe there is a " coil pack" attached to each plug. Can you help me in selecting an appropiate plug? I do also haul campers 16-28 ft. And snowbobile trailers. Im just looking for the best fit for my vehicle.

Sounds like factory is good for your vehicle. But what I put on my vehicles that I found working great are a type of platinum pulse plug, they are more expensive but man do you notice power.
