Great EBCS

At first when I bought this product it was malfunctioning, however it turned out to be user error. On installation I certainly recommend reading Perrin's instructions very carefully because I managed to damage the valve on the inside with a different screw than was provided because of a different mounting position. Despite me royally screwing the installation up Perrin was more than happy to make sure that I was taken care of and over-nighted me a new solenoid to replace the damaged one. A+ customer service and A+ on quality since I have now been running this for quite a few months now with no problems on my 2018 STI.

I recommend this product
