I purposely bought the 4.3 Silverado because I dont really need the V8 power( Why go fast in a heavy truck....Ill just go buy a used Fbpdy to go fast with :happy . However, I would like to squeeze some extra HP out of it with a CAI. Are there any out for the 07-08s? They seem hard to find. Also, will towing small loads such as band trailers be a problem for the V6? Its a enclosed trailer about 10 ft long and usually filled tight with amps, speakers and monitors. Our 01 5.3 Tahoes pulls it like it not even back there. Thanks!
