Perrin Turbo Inlet Hose 37min install for 10HP!

A major built in flaw from Subaru is the wimpy turbo inlet tube. Made from weak plastic and corrugated rubber to, it's a recipe to fail! And fail they have. A recent inspection of our 2002 WRX Project car we revealed two failures. One leak at the BOV crossover, another at the turbo itself. This caused vacuum leaks, drivability was terrible. A quick 37minutes of labor later and idle was smooth, no leaks, no backfiring and BETTER performance! The superior construction of the PERRIN inlet has solved the problem!

The PERRIN inlet hose is also able make more HP, quicker throttle response, and improve acceleration! By removing the pleats found in the OEM hose, increase the internal diameter, and mirror smooth finish reduce intake restriction. Thus more HP. Check out the charts page for dyno results! (Will be there shortly!)

Also, PERRIN has an advantage over other brands. Our inlet hose is the only one on the market today that does NOT require the removal of the intake manifold! That is HUGE. Think about it, no fuel to drain, no water lines to remove, no gaskets to purchase, less nuts and bolts. A huge advantage if you do it yourself or pay a technician. Instead of paying for 4-6 hours labor and parts, you should only have to pay for1-1.5 hours and no extra parts.

The instal was relatively easy! For the price you can’t beat it


Thank you for taking the time to leave a 5 Star Review of the Perrin Turbo Inlet Hose! The Perrin Turbo Inlet replaces the flimsy OEM inlet increasing air flow creating more horsepower, decreasing turbo spool time, improving acceleration and increasing throttle response! The reinforced silicone material will not collapse and is built to last!

perrin quality product

I've been running this for some time in blue on my car. it worked with my stock air cleaner set up with an ihi vf48 turbo. it's a great product, just be really carful with all the plastic 90s. I would recommend buying all new lines if your car is older. but all in all, a great, strong, and smooth product.

Thank you for your 5 Star Review of the Perrin Turbo Inlet Hose! Your advice about being careful with the plastic 90s is noted, and it's always a good idea to inspect and replace any worn or damaged lines on an older car as they tend to dry out and crack! This inlet is going to provide more reliability and performance over OEM which is prone to cracking and collapsing! We appreciate your business and hope you continue to enjoy the improved performance of your vehicle with the Perrin Turbo Inlet Hose!

Great product, tough install

Looks great but be prepared for a fight. Well written instructions! *Be careful with these older cars, you can easily break something else in the process*


We appreciate your 5 Star Review! The Perrin Turbo Inlet Hose is a fantastic replacement over the OEM plastic! The reinforced silicone construction ensures quality and reliability that will not collapse under pressure! The larger diameter and smooth inner design reduces restrictions, increasing airflow and ultimately more HP!
