DETAILS

Improve airflow, increase horsepower, and add style to your engine bay with the Perrin Turbo Inlet Hose!

Silicone technology allows Perrin to design a turbo inlet hose that is better in all aspects than the OEM part and increases your engines horsepower and performance.

The 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, improves acceleration and increases throttle response.

The 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.

Features:

  • No Tuning Required: Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without tuning required, although more power can be gained with proper ECU tuning!
  • Plug-N-Play Crank Case Vent Connector: The only turbo inlet hose on the market to include an OEM-like connector that does not require defeating the emission control device.
  • Smooth Nylon Coupler: Utilizing a glass filled reinforced nylon coupler, allowing for an even smoother transition from intake to turbo inlet hose while also maintaining rigidity and strength
  • Reinforced with Stainless Steel Support Wire: The OEM part has a tendency to wear down and tear down over time. The wire reinforced silicone in the Perrin inlet hose is much more durable.
  • Blow Off Valve Connection: Bonded into the layers of silicone is a machined aluminum insert giving you a solid blow off valve hose connection and makes installation even easier.
  • Large High-Flow Spigots: 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 these hoses are glass reinforced nylong (Rated at 400 degrees F) which will withstand engine bay temps found from normal driving to extreme racing conditions.

Needed especially for an older subie!!!

My old turbo inlet was gross and falling apart near the mouth of the turbo. The installation can be done without having to take the manifold off but can be a bit of a pain to do so. I found it harder to take the old oem inlet of since I had to do a little bit of cutting to get it off. If you have an aftermarket aluminum intake like I do, you do no have to use all of the hardware included. According to the website, no tune is required.

Hello,

Thanks for your review! Glad it solved your old turbo inlet issue and installed with minimal hassle.

A must have

Getting the old inlet hose out was the easy part. Putting this in takes a lot of time and patience but definitely worth the effort. Would recommend changing this and the intercooler hoses out at the same time if those were on your list as well. Would note that there was a little bit of a space issue when connecting the OEM post MAF hose to the new inlet hose, but nothing dramatic.

KB,

Thank you for your 5 Star Review! We are glad to hear that the Perrin Turbo Inlet Hose was a must-have for your vehicle. We apologize for any inconvenience you may have encountered during installation, but we appreciate your patience and effort. Your suggestion to also change the intercooler hoses at the same time is a great tip! We will definitely take note of the potential space issue when connecting the post MAF hose. Thank you for choosing Perrin from Subimods and happy driving!
