Hi, I'm new to this forum and was hoping I could find some expertise here. I've got a '00 Silverado 5300 and I'm looking for ways I can improve my gas mileage. Right now I'm getting around 15-16 with mostly highway driving. I'm considering a high-flow air filter such as K&N or Fram Air Hog. Also, would a cold-air intake help? I've seen some K&N's for about $250. Any ideas? Thanks.
