    Took more time getting the stock unit off than putting this one on!

    Big boost filter kit

    Posted by Justin on Jun 25th 2021

    I read all the other reviews about them says it wakes the motor up and that you can hear and feel and different and you sure can. All I have done to my truck is a 4inch striaght and a 25 hp tuner and this intake woke them truck up like I unhook another load. I would recommend if you like the noise in the cab, if you don’t want to listen to turbo noise then get the 6637 filter.

    Would be a nice option to have a hole in the connection pipe for the air restriction gauge.

    I would recommend this 100%. Easy installation probably took about 30 minutes at the most. Well done Riff Raff!

    Filter kit

    Posted by Jimmy on Apr 16th 2021

    I got the blue version as well as the new battery tray and filter bracket. The bracket is still on the bench as I have not gone to the hardware store for fasteners and washers. The entire instillation of the kit and battery tray without the bracket took about one hour as I used some of the time to do some cleaning as well. Easy kit and the truck does seem to run better with it. Also no more cracked filter box.....

    Came with everything I needed to install the kit and is a very nice quality part, would highly recommend to anyone interested in installing an aftermarket air filter.
