I just installed a new free flow air kit from streetsmart on my 94 4.0. It has the K&N filter and the truck now has good low end and accells like a bat.
My question is does the battery need to be disconnected to reset the maf to adjust the computer to the new airflow it is seeing.
This kit is easy to install, its set up for the 95-97 which has a lower upper radiator hose, but works fine on the 94 if anyone is interested.
