I know from experience that you don't wanna cheap out when buying a map sensor. If at all possible you really really want to buy OEM sensors. I went through 5 AutoZone map sensors before I finally just bought an OEM one. Luckily Napa had one for like $70 and the guy knew me so he gave me all kinds of discounts and it came down to $49. This was all on a Jeep so prices may vary but importance stays true.
Good luck.
