No, their is no specifically made supercharger kit for V6 03 and 04 4runners. Something to do with the ecu. What's so different between 03-04 and 05 ECUs? Now the supercharger itself will bolt on though.
I've looked for a plug and play ems for my year runner no luck. Have aem ems for the s2000 on e85 and hondata on q16 for the hatch. No ems solutions for the truck though, no wire cutting for me as I have to pass obd2 check yearly and need to go back stock so a universal is a no go. Any options?
