    Spendy but great for high boost 3 years ago
    Easy to install, quality packaging and product. Its also a lot cheaper than an oem piece from the dealership and reads psi better.

    transparent 4 years ago
    Easy install, takes less than 5 minutes to do. Follow the instructions that are provided to modify your accesport (if you can't do that don't install this without help from your tuner) and enjoy the absolute transparency that you just paid a lot of money for. Now, take this nice and not so shiny item to your tuner and see what magic they can coax out of your pride and joy.

    • Q: Good for 05 wrx?  ericclover465153 years ago

      On the Perrin website, it shows this same map sensor being good for 05-07 wrx. Same part number. Why is that?
      • 0 of 0 people found the following answer helpful

        A:  Our initial confirmation is what we have listed, it may be possible Perrin has found it to work on the 2005 but we do not have a guarantee at this time.

    • Q: which one  akumar4 years ago

      will this suit 2002 (map 2001) wrx/sti ? or do i need both iat & map sensor
      • 0 of 0 people found the following answer helpful

        A:  This will bolt on to 2002 WRX models, but it will not be compatible with the stock ECU. The IAT is built in to the stock MAF sensor and it does not need to be changed unless you switch to speed density tuning.

    • Q: Would this help increase my HP  guest55fc85202a8d2524548bac6f4 years ago

      I have a 2015 STI. Ive installed a COBB intake, Cat back exhaust, Cobb access port stage 1. I am currently getting a peak boost of 20 PSI. Would this increase my boost safely?
      • 0 of 0 people found the following answer helpful

        A:  This sensor will not raise the boost, but is capable of reading higher boost pressure than the stock sensor. In order to raise the boost, you will need a custom tune or wait for Cobb to release Stage 2.
