This is the 5.4 Liter Roush Intake. If its the same exactly def buy the airraid. Super easy install and def a big difference. Sounds like its roaring under the hood too

I fell for all the hype of the K&N and asked Santa for one for Christmas. I put it on the 26th and it has sounded real good all the way to the frequent stops at the gas station ever since! That's the only difference I noticed (less mpg).
