Yea my friend has a 2004 Reg. cab silverado an is looking to buy a new cold air intake system an throttle body spacer but he doesnt know wich one to get. He was going to get the K+N intake an Airaid throttle body spacer. But lately people have been telling him to get the new AEM Brute Force intake that comes with a throttle body spacer in the kit. An every one he talkes to says the AEM intake is better than K+N. What do yall think, wich is better?
