DETAILS

Perrin Turbo Inlet Hose Red 2015-2021 WRX / 2014-2018 Forester XT | 3.0" Diameter | High-Flow Silicone Turbo Inlet

Overview

The Perrin Turbo Inlet Hose is a direct replacement for the restrictive and often failure-prone factory turbo inlet hose on turbocharged Subaru WRX and Forester XT models. This upgrade is designed to improve airflow into the turbocharger, resulting in enhanced throttle response, quicker spool times, and overall better engine performance. It is ideal for Subaru enthusiasts looking to unlock additional power potential, especially when combined with supporting modifications.

Engineered with a multi-layered, fiber-reinforced silicone construction, the Perrin Turbo Inlet Hose offers superior durability and heat resistance compared to the OEM rubber hose. The smooth internal surface and increased 3.0" diameter reduce turbulence and airflow restriction, allowing the turbo to operate more efficiently. CNC-machined aluminum fittings ensure a secure, leak-free installation that maintains OEM-level fitment quality.

For Subaru owners, this turbo inlet hose not only enhances performance but also increases reliability under high boost conditions. Its reinforced design prevents hose collapse, a common issue with stock parts, ensuring consistent airflow and improved acceleration. This upgrade is a practical and effective way to support your turbo system’s efficiency and longevity.

Be prepared for the boost difference!

I purchased this, the cold air intake, the charge pipe, and the top mount intercooler.
This is not an easy part, be prepared for a challenge. And get an extra set of hands to help for the day. And, DON’T just reconnect your battery and take a test drive. You’ll need to perform a relearn if the battery is disconnected longer than 25-ish minutes. (Mine had been disconnected for about 12 hours).
But, I can’t recommend a more powerful combination of bolt on’s ! Definitely a huge gain in performance!

Jason,

Thank you for your 5 Star Review on the Perrin Turbo Inlet Hose in Red. That is a serious combo of upgrades you installed—nicely done! And great tip about the relearn process. Boost on!

Regards,

Best decision yet

Easy install, and can definitely tell a difference in the sound of the turbo and a little bit of power as well. You can’t go wrong with this it’s a must have.

Bill,

Thank you for taking the time to leave such a positive 5 Star Review! We are thrilled to hear that the Perrin Turbo Inlet Hose has made a noticeable difference in the sound and performance of your WRX. It's always great to hear when our customers are satisfied with their purchases. We appreciate your support and recommendation. Happy driving!

Regards,

Works great

Good quality and comes with everything needed

Alexander,

We appreciate the 5 Star Review! They Perrin Turbo Inlet Hose is a direct replacement for factory. The flange on the factory hose compresses and deforms which causes vacuum leaks! Perrin has designed a billet flange that will not deform along with the silicone hose that will not break down and allows for better air flow to your turbo!

Yriel,

Let's face it the OEM Turbo Inlet lacks support and can compress and deform. The Perrin Turbo Inlet Hose prevents this and allows for the best performance possible for your WRX! Thank you for the 5 Stars,

Regards,

Good product

Would have given 5 starts if it weren’t for the small amount of cutting for the bfv and the fact that the hose clamps don’t really work well on the small inlet tubes. I’d feel a lot more secure if they had more surface areas to hold onto. Otherwise a great product. Really improved throttle response.

Bret,

Thank you for your feedback! We appreciate your thoughts on the Perrin Turbo Inlet Hose. Cutting for fitment can be a bit of a hassle, but we are glad you noticed an improvement in throttle response. Enjoy the upgrade!

Regards,
