Anyone running one of these? Are they worth having? I`m debating if I should put it on my car or not.
I personally don`t think it will do anything. But if someone knows otherwise, please let me know. Thanks.

I have one on my Explorer. I didn't really notice any difference in how it runs.[sm=badidea.gif]

I don't have one, but I'm told it's a waste of time and money.

I have one but it came on the car along with the k&n FIPK. I think its the cause of the whistel i get when i give it gas.

I've heard they are a waste but if you already have it then I would definitely install it.
