High quality as expected from Cobb, keeps tuners happy all over…

Some say this is a gimmick or it’s not necessarily needed. For those true Subaru enthusiasts, and tuners this is a must for smoothing out that fuel response curve and getting a better dial in to your injectors. Nice quality. I’m not sure why Subaru changed this specific plumbing from the 2008+ models but they should have left it the way it was imo! Thanks Cobb!

STIRAN,

We appreciate your 5 Star Review! Your insight on the COBB Fuel Pressure Regulator Kit is appreciated and spot on—Subaru tuners definitely know the value

Great Product and Delivered Fast

Recieved the product very fast and had it on the car with in 30 mins. Did run into a minor issue where I had the lines on backwards making the car run terrible. But after switching them to the correct way it has ran great since. I used the instuctions from Cobb which helped a lot as well.
