can someone tell me what these 3 parts are. im putting a new intake in and wanted to most likely replace them. if they are reusable lmk. guessing 1 is some kind of sensor? 3 is just a plug? idk what 2 is, it had a small wire that just pushes onto the post.
pic 1 is the ACT sensor.. (you need that)
pic 2 is the temp sending unit for the gauge in the dash (need that too)
pic 3 is a pipe plug, if your new intake has a hole there, then you need to put that plug in it.
Well I would at least replace the ACT.... that's what I'm doing, the temp sending I don't care about, I'm moving that to my thermostat housing (so the stock gauge still read's something) I'm installing a mechanical gauge in the stock location on the intake, so I can get a true actuate reading over the stock one.
A little late, but, if you haven't got this project finished yet use a Teflon sealing paste vs Teflon tape on the sensors when reusing the old sensors. Teflon tape can prevent grounding which leads to inaccurate signals from the sensors. New sensors will likely have a sealant already applied to them.
