Worked perfect on the 98 legacy I installed it in. One hose tube had been damaged by the Uninstaller I discovered right out of the box. But I replaced it with the same part out of the bad one I had just removed. Car still wouldn't run until I unplugged the M.A.F. then it idled. Which told me that the car computer sent info to the I.AC. and it adjusted accordingly as it's supposed to. So I got a M.A F sensor from a local junkyard. Installed that and the car runs perfect now.
