Many customers experience a burning oil problem or blue smoke coming from their exhaust after installing aftermarket J-Pipes or turboback exhaust systems. Installing these parts on 2015+ WRX's or 2014+ Forester XT's causes a change in exhaust pressure, allowing engine oil to escape out the turbo seals. This leaks into the exhaust creating the burning oil smell and blue smoke that many people see. Cars with catless J-Pipe setups experience this issue much more than cars with high-flow cats.

This turbo sump restrictor was easy to install. Helped alot with blowing smoke due to being catless. Great addition for just 30$ and of course IIR always hooks it up.
Honestly one of the cheapest thing you can get for your car and its actually helps alot, like very noticeable difference.
I order this part 2 days ago, its already at my front door!!! Wow ... the quality of this part is outstanding. Id like to appreciate IIR for the unheard of customer service and for having quality you can count on!!!
took me a week to install this because i was waiting for the pvc hose replacement at the dealership once arrived they event did full installation of this product. smoke reduction was incredible.
