    DIY airfilter

    Posted by Lance Opperude on Feb 27th 2017

    What a GREAT product. I was looking all over for a DIY airfilter system. The filter has expanded metal inside and out so there is no worry of collapse. I choose to get the slip on prefilter which has the Riff Raft logo and REALLY dresses the filter nicely. Everything fit perfectly and was super easy to install. I did get an extra filter to save on shipping. Overall DEFINITELY well worth the money......

    Great Set Up!

    Posted by Tyler on Feb 20th 2017

    Easy to install. Gave the Excursion better throttle response and maybe 1mpg more. Great mod! It definitely makes the engine BREATH a lot better. If you are thinking about it...Just do it!

    AFE UPGRADED FILTER

    Posted by Unknown on Feb 3rd 2017

    This is a great kit for the money and fits in the engine bay nicely. Very easy to install. Get the cover for it too and it adds a nice touch to the overall look. You will definitely here it when under boost. Driving and cruising with no load and you can't even tell its there.

    Optimum flow with superior filtration

    Posted by Alan VanGroningen on Jan 31st 2017

    This intake might be one of the best on the market, it gives optimum air flow but doesn't compromise filtration. The Donaldson 6637 filter does a spectacular job at filtering out any dirt in the incoming air of your vehicle pair that with the riffraff filter cover and there's no way dirt or water can enter into your motor thru the intake. Plus it makes it look amazing under the hood, and sound amazing while your driving.

    Best performance mod yet

    Posted by Unknown on Jan 13th 2017

    Did a lot a research on mods on a budget and found that this mod was by far the most recommended. Glad I did. Great pedal response, instant performance boost. Not sure of the fuel savings... can't keep my foot out of it. Easy to install.

    Perfect upgrade for the price

    Posted by Ryan on Dec 27th 2016

    I have purchased this kit two times now for two trucks and am still very happy with them. Not a huge power adder but definitely makes a difference over stock. My 7.3's drive so much better with improved throttle response and merging on the highway is much easier. Well worth the money.
