I ordered me an Airaid Cold Air Intake and Throttle Body Spacer today. I know there's diverse opinions on these two add-ons, but I wanted both of them so I bought both of them. I hear people say the TBS spacers are paperweights, yet they have never run them; I hear people say the CAI's are a waste then the next guy claims 10HP increases. Some people say that if the TBS's truly worked that the manufacturer would install them from the factory, but I find that hard to believe because most manufacturers offer a full line of OEM aftermarket parts and if this was the case why do they give me a 4x4 truck with street tires or a V8 with no trailer hitch. Anyways, I am opening up this can of worms so let's here the opinions!!!
