Hello, I must change my Bar Map sensor on my Saubaru STI 2009! the original parts cost about $ 300 I have seen on EBAY less expensive! but I wonder about the brand? Perrin and Omni Power, is what you know about brands? quality or No? thank you

Aftermarket MAP sensors will require recalibration of the ECU. If you're not comfortable / able to make said changes, you should replace it with an OE unit. Otherwise, you could run into serious issues with your vehicle.

Perrin makes decent stuff, however when it comes to sensors I've personally found myself as a denso guy. I've had the best overall luck and reliability with them. They likely make the Subaru oem unit

ok thank for the advice ! and for brand perrin and Omni Power ?
Are you able to calibrate the ECU to account for the aftermarket MAP sensor? My brand recommendation means nothing if you're not; you should be reaching out to the person tuning the vehicle and find out what they want you to install.

If it were me, I'd go AEM or Omni, but I DIY my ECU calibration.
