PERRINPerformance PSP-ENG-628 Turbo Sump Restrictor

So far, so good!

To think that this lil device could make my 2017 WRX stop smoking so much is absurd! If you've got a modified WRX 15-20 with a aftermarket downpipe you'll need this. So what does it do you say? It's able to level out the vacuum levels on your turbos seals, therefore not allowing oil to be burned at a rapid pace. Buy it before you ruin your exhaust!!!

I was skeptical at first, but the end result is night and day! I don't see (or smell) the blue smoke of burning oil that I was experiencing at idle and hard acceleration. Wish I did this when I first went stage 2, but I thought I was relatively safe from the problem with a catted J-Pipe. So, this part should be in your cart regardless if you are going catted or catless.The hardest part honestly, was getting started. Being hesitant on cutting the hose and thinking about making a mistake; but once you get past that, it's easy. Remove the left radiator fan to make this much easier too. Highly recommend!

The media could not be loaded.  Have a 2017 wrx. Easiest way to install is to remove the left radiator fan and to use a sharp knife and cut about an inch below the sensor and then about a half inch off or however wide the restrictor is. I just used two of the bigger clamps that were provided. I did not use a lift or remove the hosePretty easy install

I was having issues with burning oil on my stage 2 tune and so far so good with this little mod only took about 15 minutes to install and got rid of the Stubborn smoke on idle issue!

This solved all the oil smell and visuals ..very satisfied with the product!

Fast shipping and quick install!

Great product
