i need to get one for my car. who is the best for the money? So far i have seen one from TPIS and MSD. The MSD one is $80 which is way too much for me. Anyone know of one for around $40 maybe??? thanks for the help.

 

i have a bosch 3 wire in my bird i think it was $43 from auto zone

 

do you know the part number? how did you splice it into your system?

 

I used an AC Delco one.

Part # AFS-74

This was the cheapest heated one I found at the time.

To hook it up is simple. The purple wire is the signal that goes to the wire you have now. The other two wires are tan. These you hook to ground and +12 IGN.

Mark.

 

thanks man.

 

Should you opt for the heated one if planning to replace it. I have a 89 MAF TPI. Can I use it?
