So I was looking on the internet, and found a K&N cold air intake for sale and wanted some imput. Is this a good brand. The price is 150 and it comes with everything needed and he says it works on 05-08 toyota tacomas. Should I wait to get a TRD? I'm a little concerned about my warrenty, but I think I can just switch it back to the stock if needed. What do you guys think?
