I bought a "Air Intake System" through eBay - eBay Item # 2421537401

Description:
* Brand New Air intake
* Air intake dsigned maximum flow air with high performance
* Made by T-306 Aluminum Chrome Finished Intake pipe
* Air intake increase 10-15 horsepower
* It includes all mounting hardware, blue vacuum hoses and_Air Filter_
* Easy to installation, no modification needed

It costs $39.99 after shipping and insurance . . . did I get ripped or do you think it will make a difference other than looks under the hood?

Thanks,
Melissa
