Subaru Turbo Inlet Hose by Perrin Performance

The PERRIN Turbo 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, improves acceleration, and increases throttle response. The PERRIN Turbo 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. The PERRIN Turbo Inlet Hose is the only turbo inlet hose on the market to include an OEM-like connector that does not require defeating the emission control device.

The PERRIN design has been further improved with the use of a glass filled reinforced nylon coupler, allowing for an even smoother transition from intake to turbo inlet hose while also maintaining rigidity and strength. The PERRIN Turbo 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. All spigots on the PERRIN Turbo 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.

A must for your subaru

She is a tight fit but take your time. I found that wd40 helps a lot! Looks great on the motor too!!!

Tight fit, but great results

Great quality, relatively straightforward install. Goes in easiest if you plan on removing the intake manifold.

Pros: more turbo sounds, noticeably faster spool times on low end

Cons: tight fit around the power steering pump

A great upgrade.

Perfect Fit

This is so much better compared to the OEM inlet! On top of the quality, it shipped to my house in barely less than 2 days from order! The installation and fit was perfect. I figured I might as well replace the factory inlet since I was deep into my engine bay installing an intake and AOS. 10 out of 10 would recommend!!!

Worth the extra money I feel.

Yes, there are a lot of other silicon inlet pipes out there. Heck, for all I know they are all the same. Yet for some reason I kept coming back to Perrin and am glad I did purchase this over the other offerings out there. Word to those who have never done an inlet pipe on any Subaru, you might be in for a painful install as these are not easy without the intake manifold off the block. But, I happen to require that the intake manifold is off so the install was super easy and definitely made it faster to install. As for not having the intake manifold off the car, well, I know it is possible to do this. I have heard/seen that it can take about a full day to do this if the intake manifold is not off. I cannot attest to that though.

Overall, I am glad that I went with the Perrin Turbo inlet. Good quality part as I was expecting. I also matched it with the Perrin Afta Maf hose as well to keep them the same. That is another reason I chose Perrin.

Thanks MAPerformance for the fast delivery as well!
