Re: TPI upgrade to HSR Q's
All the sensors come off the Tpi and are reused on the hsr.As for the fittings..judging from your pics for what they cost I would use new ones.those look old and beaten..fittings arent expensive.There are many posts on the alternative induction board that will list all the fittings,hoses,thermostat housings etc other have used for the complete swap that work well.Search the archives there and you will find everything.
