I did the J/Y budget MAF upgrade this afternoon. I bought a 95 GT Mass Air Flow Sensor for $20 and an adapter off of EBAY for $11. I cleaned and painted the housing and used MAF cleaner to clean the MAF before installing. The adapter worked perfect but I did have to cut about 1.25" off of the CAI tube to make everything line up. I'm happy with the results so far. Idles smooth, no CEL, and great throttle response. Well worth a little time and $31
