Features & Product Details

The PERRIN Turbo Inlet Hose has been designed to be a direct replacement for your factory inlet hose which is prone to failure after years or mileage of use. Usually, the stock turbo inlet will tear at the connection side of the turbocharger which can affect performance, throw a check engine light, and even reduce the power. PERRIN relieves this issue with their robust example.

Here are key features:

  • Multi-layered heat-resistant silicone fibers
  • Stainless steel support wire
  • Larger diameter with smooth interior walls
  • Improves horsepower and throttle response
  • Black finish
  • Hose fittings and clamps provided to make this part ready for the installation

    PERRIN Turbo Inlet Hose Black ( Part Number: PSP-INT-421BK)
    Very Happy 9 months ago
    5out of 5stars

    2014 WRX. OE inlet was torn, chose this to replace it. Quality part; Everything fit without modification. Construction of the inlet tube itself is great and the included fittings are some of the nicest ones you can get (the "ej" or Eldon James). I tried installing both with the intake on and off. The latter is easiest to do but you can do it with the intake on if you leave the elbow fittings off the tube until you get it on to the turbo. Quick spray of wd-40 or other lubricant and all the fittings push in and hold very well. Zip-ties aren't required for the fittings into the inlet tube but there's enough room to do it (if you choose to). The worm-drive clamps included are the shielded type, so tehre's no worry about cutting into the tube. Performance is a 3-star as I didn't notice any "performance gains" from it. The largest gain you'll see is a vast improvement of reliability. Value is 4-star as if you don't "need" to do this (ie your OE inlet isn't torn) then its a bit much. However, if you need a replacement I'd look at this. Overall very happy 5/5.

    I have a 05 LGT and this is the worse. It literally took me 3 hours to put in. After installed and a simple test run everything is fine PVC inlet has to be shorten. Alot of modifing.

    Could not be happier  2 years ago

    While turbo flat 4's are never the easiest to work on, this inlet hose went in much faster than expected. I installed while doing a turbo swap which helped because the hardest part was getting the hose on my turbo, had to loosen my intake manifold so ordering a set of intake to TGV gaskets may be wise. no trim needed matched up perfect with my Cobb intake. It is a massive help that all the ports can be set in any direction, freed up space by rerouting the lines for my oil catch can system so satisfied with this purchase I have already noticed less turbo lag.

    Perrin turbo inlet  3 years ago
    4out of 5stars

    I replaced mine preemptively and although there was oil pooled up in the ribbed section my stock inlet still had no tears. Wasn't really that bad, I got the old inlet out without hacking off any of the fittings, then you start to feed it through and connect and clamp each connection as you go. I used some oil to lube everything up. It's definitely a lot prettier than the stock inlet.

    Smoothed out the ride 4 years ago
    5out of 5stars

    I'm rolling a 2012 WRX hatch. Had the Cobb SF intake, Perrin TMIC, Cobb Crank Pulley, Cobb down pipe and SPT cat back with a Stage 2 flash.. I added the Perrin turbo inlet, Grimspeed Crosspipe, and Grimspeed up-pipe simultaneously. The car was fast before, but the last upgrade smoothed out everypart of the driving experience. The car is my faster off the line, spools up much quicker. I believe I made solid power gains, but don't have any dyno data to prove it. The bottom line is I've now got great airflow from the intake all the way through the motor, the thing is just balanced. As far as the install goes, it's a PITA the first time around. You've got to surgically pull as much stuff out of the way in order to slide the turbo inlet in. Connecting the vaccum hoses is tricky.. I made the mistake of accidentally pulling some additional vaccum hoses out and not realizing it. I kept throwing a CEL, until I went back in and basically reinstalled the part. Now it's cherry! Tips.. 1) You've got the cut two of the hose attachments on the stock inlet pipe to get it out. 2) Allign the elbow pieces in similar directions to the stock inlet pipe. 3)Prestrech the inside of the vaccum hoses before attaching them. 4) Use a touch of oil in the elbow pieces to help slide the vaccum lines on. 5) Use zip ties or hose clamps to make sure all the lines stay in place. Bottom line.. Probably no the first mod, but if you've got an aftermarket intake on there, you may as well match it with a high volume turbo inlet pipe. Hope this helps!

    • Q: Boost Creep concern  Tomas Franks4 years ago

      If I run a full catless turbo back exhaust (x2 bungs), CAI, boost solenoid, 50/50 BOV, and this product...can a pro tune not eliminate boost creep should it happen after installing this item?
      • 0 of 0 people found the following answer helpful

        A:  When running catless it is always a possibility boost creep may be an issue, oftentimes the only way to fix this would be to go with an external wastegate.

        A:  This part is installed before the turbo. Highly unlikely this is the cause of a leak.(leak could be pre-existing) If there is a boost leak due to part, it would be: a vacuum line connection, or BOV failure.

    • Q: Anybody running this with stock airbox and catless DP?  whitesox311310374 years ago

      I installed this and have a bit of boost creep now, I saw someone else saying the same thing, but most people i know that have boost creep have cold air intakes, not running stock airbox.
      • 0 of 0 people found the following answer helpful

        A:  We have not tested this inlet with the stock airbox and a catless downpipe. If you already have a custom tune, then you may need to modify the tune slightly to correct the boost creep.

    • Q: installation question   dgalupar569365 years ago

      Is this installed at the other end of the intake? And how does it go with instructions?
      • 0 of 0 people found the following answer helpful

        A:  Perrin provides instructions with the product, and also lists the instructions on their site. This goes under the intake manifold and goes between the intake and the turbo
