Here, you are looking at the Perrin Turbo Sump Restrictor for your late model FA20-powered WRX or FA24DIT-powered Subaru!

Fix both the burning oil smell and blue exhaust smoke problems by installing the PERRIN Turbo Sump Restrictor!

Key Features:

  • Eliminate burning oil and blue smoke
  • No tuning is required after installation
  • Makes the turbo sump more effective
  • Creates a balance of exhaust pressure and vacuum on turbo seals
  • Reduces the amount of leaking around turbo seals
  • Does not change oil flow to turbo

Why You Want This

Many people experience a burning oil problem and blue smoke coming from their exhaust. This problem can worsen after installing a cat-back exhaust, J-pipe, or turbo-back exhaust system. The installation of these parts can cause a change in exhaust pressure that allows engine oil to escape out of the turbo seals, causing the burning oil smell and blue smoke. The PERRIN Turbo Sump Restrictor quickly eliminates this issue!

How the PERRIN Part Works

The PERRIN Turbo Sump Restrictor makes the turbo sump pump more effective at sucking oil out of the turbo sump. This in turn creates a slight vacuum on the turbo sump creating a proper balance of exhaust pressure and vacuum on the turbo seals, significantly reducing the amount of leaking around the turbo seals. This does not change the oil flow to the turbo or create any wear.

Plug & Play

Our plug-and-play Sump Pump Restrictor is designed for ease of installation on most 2018 and newer Subarus. With no need for cutting hoses, installation is quick and effortless.

No Tuning Required

Finally got around to getting this, it is a very easy install and didn't expect a $45 part to fix the smoke. Installed it and started the car from a cold start, no smoke, it works perfectly.

Easy install, no more smoke

My cars been modified for a couple of years and I’ve always noticed a burning oil smell in my exhaust after installing my mishimoto j pipe. Recently I noticed my cars exhaust was a little smokier than usual so I decided to buy this product. Install was super easy. Hardest part for me was figuring out how to disconnect the radiator fan electrical connector(not hard at all). Once I got that disconnect I removed the blow by diagnostic connector. Used a thermostat screwdriver to remove the o ring and put it on the new Perrin sump restrictor and put it all back together. Super easy install and noticed pretty quick how the burning oil smell and smoke disappeared! Wish I installed this years ago, but glad I found this product! Highly recommend to anyone with an aftermarket exhaust!

Instructions were spot on and had no issues at all with installation!

Ryan,

Can't hurt...

I put this in with under 30,000 miles on my '21 WRX, which isn't smoking, but figure anything that can help reduce oil consumption is probably worth $50. Removing the ring from the blow-by diagnosis connector was a challenge, but eventually cooperated and everything went back together easily with no CELs after buttoning up.

Mr. X

Thank you for sharing your experience with the Perrin Turbo Sump Restrictor! It is great to hear that you decided to proactively address potential oil consumption issues in your '21 WRX by installing this product, even though your vehicle wasn't experiencing smoking. We are pleased that the installation went smoothly overall and that you did not encounter any check engine lights (CELs) afterward. If you have any further feedback or need assistance with other automotive parts or modifications in the future, please feel free to reach out. Your satisfaction is important to us, and Subimods is here to help! We appreciate your 5 Star Review!
