Subaru Inlet Hose 08-13 WRX & 05-09 LGT
Subaru Turbo Inlet HoseSilicone has been used for years in Aerospace and medical equipment,Silicone is now seeing a resurgence as a durable and superior material in performance motorsports. Silicone technology allows us to design a turbo inlet hose that is better in all aspects than the OEM part and increases your engines horsepower and performance. |
|
|
Smoother Air Flow To TurboThe PERRIN inlet hose is perfectly smooth on the inside and has a significantly larger internal diameter than the OEM part. The increased air flow by removing the pleats found in the OEM hose makes more horsepower, decreases turbo spool time, and improves acceleration. |
|
SS Internal Support WireThe PERRIN inlet hose is reinforced with a stainless steel support wire that is embedded within the silicone layers. The support adds rigidity to the hose and prevents collapse when used with restrictive filter elements and large turbo applications running extreme amounts of boost. Watch the Video. |
|
Blow Off Valve ConnectionThe PERRIN inlet hose has a machined aluminum insert which is bonded into the layers of silicone, giving you a solid blow off valve hose connection and makes installation go even easier. |
|
08+ Specific DesignThe PERRIN inlet hose for the 08+ WRX and Legacy GT is the only inlet hose specifically made for this car. This is not just the STI version adapted to fit like other inlet hoses. This is specific to the engines with the plastic intake manifold with specially designed spigots and BOV fitting. |
|
Large High Flow SpigotsAll spigots on the PERRIN inlet hose are 1/2"ID for maximum flow from crank case vents and other vacuum connections. All connectors used on our hoses are glass reinforced nylon (rated to 400 degrees F) which will withstand engine bay temps found from normal driving to extreme racing conditions. |
|
InstallationThe PERRIN turbo inlet hose is the only hose on the market today that does NOT require the removal of the intake manifold! This cuts the install time from 4-6 hours down to just 1 hour! We achieve this by changing the placement and type of spigots used. This design also means NO more rerouting of crank case vents and hoses! No need to purchase extra gaskets or deal with fuel and coolant spills! |

What People Are SayingDon't Take Our Word For It |
| Dear Perrin, I am new to the Subaru scene after about 10yrs with Hondas. Many projects and parts have come and gone but I have to say that your turbo inlet hose is the best value modification I have ever bought. It is just plain cheap for the high quality construction and effectiveness of this simple part. Compared to stock, the inlet gives significantly improved spool up and torque, making for better responsiveness and drivability. And when combined with the AccessPORT, my Forester XT is a whole new car! Thanks for the hard work developing it. It will have me coming back for more! James Takayesu Forester XT Owner |

Turbo Inlet Hose Test on STILike all tests we do, we start out with a few baseline runs and then as quick as possible swap out the part we intend to test. In this case when we swapped out the OEM inlet hose for the PERRIN part in 45minutes, which was somewhat controversial as it normally take about 3 times longer than that. The freer flowing nature of the turbo inlet hose gains about 10WHP at higher RPM and spools the turbo faster. |

Turbo Inlet Hose Test Boost ResponseYou can see in this graph how much faster the turbo spools up! This is what makes for the higher torque reading on the other dyno graph. Again, PERRIN has brought you something else no one has done before. |
