dodge cummins 1994 12 valve
look just plain and simple black smoke = higher egt's exhaust gas temperatures NOT GOOD that doesnt mean more power!
best thing is to rip the air box out get an aftermarket filter advance has them for about 20 bucks
i keep extras in my truck....take the afc housing off slid plate full forward then back just a tad but afc housing back on slid all the way forward then tune starwheel......make sure you have gauges in the truck before you do this or you may end up spending a lot of money to fix what you break
......ask anyone on here and they will tell you the same.....but just look around on the site and you will find what you need
