there's a certain supra AFM that will work on a pickup, it has a larger opening
Go to local junkyard and ask for a 1982 supra AFM, the number on top should be 22250-43110. The next step is to go to hardware store plumbing section and get a 2" to 3" rubber adapter coupling. Now remove intake hose from airbox, remove electrical connector to AFM, remove the 3 or 4 bolts and pull out the entire airbox. Remove the little adapter on end of intake hose and put on new 2" to 3" adapter. Take your cone filter (K&N universal cone filter part #2430) slide it onto the supra AFM and tighten hose clamp. Slide the supra AFM into the 3" adapter and tighten hose clamp. Plug in the electrical connector and your good to go.
