LOL - I must have got you so angry that you’re attacking me personally.

Why do you think the stock air filter is a restriction on the engine? One is your argument that the filter flows more CFM and filters better than a stock paper filter at the same time? Show me some references to tests were they say this is true. I can give you two sources that counter what you are saying;

You say there was a noticeable power increase, how much do you estimate and what acceleration time improvements (using a stopwatch) did you notice?

Then you go onto say that because you have insulated the intake pipe with truck bed liner that the hot air you are sucking from underneath the engine bay now makes "the air plenty cold entering the engine", this was surely your best line.

To sum it up. Your weapon R foam filter;
- flows better and filters better than a stock filter
- improves power noticeably and;
- improves fuel consumption by 3 MPG

All the other members on here running a stock filter setup (which are the majority) have no idea what they are talking about also! - Sarcasm intended.

And oddly ther was a noticeable power increase. And everyone knows that there are built in sound baffles in a stock airbox so you will never hear it with your stock air box hooked up. And lastly if you were to notice ther is quite a layer of truck bed liner on the pipe which not only makes it look good but insulates the pipe very well, making the air plenty cold entering the engine. I also increased about 3 MPG highway when switching to this setup so Big Kriss I think its time for you to change your name to BIG GAY KRISS. Because you have no Idea what your talking about.
