    Best mod for these trucks

    Posted by Unknown on Nov 4th 2017

    This is the easiest and best mod you can do to these trucks. It is something that wakes them up. I love the sound of these filters and how efficient they are. The stock unit on my 02 Ex was full of dirt and filter would not stay clean. This filter keeps the truck breathing and stays fresh and clean. It is a must also with this pricing.

    I bought this kit to replace a kn filter that was on my truck when I bought it. What an upgrade !! I tell all my friends where to buy this kit. I definately will buy from you again, great shipping to considering I live on the East Coast. Simple to install to.

    Wow

    Never thought a drop in air filter would make such a drastic difference. Turbo is much more audible now and there's a noticeable increase in throttle response... doesn't seem like it's gasping for air anymore. Had a K&N in the stock air box before this, and that's the last time it'll ever be in there.

    Great buy

    So it took a little more modification to instal than I expected. I had to pull the battery box out and trim all of the unneeded stock box to get the new filter to sit under the hood right. That being said I've noticed a significant decrease in EGTS and fuel economy has risen. I will say as well that you WILL notice more noise from the turbo. Not a bad thing for me. I have dealt with Riffraff on several occasions and am always impressed with speed and knowledge.

    Quick and Easy Install

    Easy installation and fit right in airbag area. Took a couple try to get it just right so the hood would close without hitting. Otherwise it's the perfect replacement filter.

    Doesn't get any easier

    I read that the factory air box does a crap job of filter rust and dirt and that it's a killer on the turbo and worst the engine. I did a lot of research on filters and this set up came highly recommended. Install was a breeze.
