2007 Silverado - cold air intake
I havent added one but a friend of mine just installed a K&N and said it added alot of noise as it is the non-covered version. I read alot of good things about the Volant systems...most really like them. He said his K&N didnt make alot of MPG difference...maybe 0.5 MPG improvement.
There are a few different kits. The two most popular are K&N and GREEN. GREEN is not good for prolonged use though because they allow alot of air, but do not filter as well as a K&N. They are also rather expensive. Your best bet would be K&N or something off of ebay. They sell an Option Racing kit for $80 on E-Bay.
