If you see me running, I would try to keep up.
Who makes the best after market cold air intake for the 5.3 ppv??

I heard the polished aluminum ones flow the best.
Yes but wrapped with insulation it works better for air transfer than plastic. It works the same way as it does with custom headers or ported and polished heads. Wind resistance is just that. The less resistance the better. I polish the insides of my other intake tubes and use exhaust tape to wrap the with insulation around the tubing. At one time I did some crazy things and used the airconditioner to cool a copper snake I coiled around and insulated to a intake to see if I could cool the incoming air. It worked great. The problem was you had to run the airconditioner that took horse power away from the motor to give cooler air to make more horse power. Next I will mount the compressor to the rearend and use the drive shaft to run the compressor instead of robbing horse power away from.the engine.Aluminum soaks and releases heat.....good conductor of heat. Plastic would insulate better and give lower intake air temps in a hot under hood environment.
