So, it obvious I'm new to this site and this is my first diesel anything. Hope to get some insite on the easy mods. I know of the egr blocker. I'd like to just delete it. But I better start small. This truck is my main set of wheels right now. I have a Tacoma X-Runner. But I'm doing body work to it. I have heard of a airbox mod. But don't know the details. And haven't looked. So can anyone help me out? Post up some links.
