Features & Product Details

RallySport Direct carries a great selection of aftermarket performance products brought to you by PERRIN Performance.

 

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 its robust example.

    Will you get what you pay for? 5 months ago
    5out of 5stars

    Absolutely! Though the initial upfront investment seems high on the surface, what you get in this part is absolute quality and performance. Install wasn't the easiest thing to do since I decided to pull the intake manifold to make sure all the connections were as tight as they could be; but after i got it all hooked up and bolted back together, the difference was immediate. This little inlet hose will wake up your turbo and if it's installed correctly, eliminate your boost leaks from the intake all the way to the turbo. Thanks to RSD for excellent choice in quality parts and Perrin for providing something that can be trusted.

    Took me 14 man hours over 3 days total. Lesson learned, remove the power steering pump to expedite this install.  1 year ago
    5out of 5stars

    The degree of PITA depends on your tools available, hardware/mods already done to the motor, and your wrenching experience. This was my first time installing a turbo inlet, but not my first time wrenching. Had read plenty reviews, watched youtube vids, and read NASIOC posts. Expected it to take about 5-7 hrs. Installed it solo on a 2011 WRX with a stock intake manifold and stock turbo. Mods already on the motor were COBB SF intake, and IAG AOS. Why did it take 14 hours? Many reasons. Biggest one was trying to seat the inlet on the turbo compressor flange with very limited space to work. Other MYs and aftermarket manifolds seem to have more working room and better vis than the stock '11 intake manifold. Tried an awl a few times, tried a paint can opener a few times to work the inlet on the compressor flange, and neither worked. Tried a wooden wedge, bungee cord, etc and nothing worked to help guide the inlet onto the turbo. The power steering pump is in the way of getting a good angle to seat the inlet on the compressor flange. Others were able to jam the inlet under the manifold and use a awl to work the inlet over the flange. I was not able to. After hours of no sucess, decided to remove the power steering pump keeping both lines attached and move it out of the way (see photo). This solved all issues and immediately had the space to easily seat the inlet on the turbo compressor flange no problem. Had I removed the power steering pump in the first place, this job would have easily taken only 5 or 6 hours max. Other issues were the BOV to inlet hose clamp having previously been installed facing aft under the manifold. That was an hour just clocking the clamp forward with long needle nose pliers a few degrees at a time. Had that clamp been facing forward initially, that would have cut another hour. If you have the IAG AOS installed, then the OE plastic valve cover PCV manifold that was capped off can be removed completely and a 1/2" hose run from the AOS straight under the intake manifold to the valve breather port on the turbo inlet. Allows for much more room to work the BOV pipe as well as the crankcase breather hose in the space under the intake manifold during install. Definitely install the 90 degree crank breather fitting and hose in the inlet before installing the inlet on the turbo. The other three you can install before or after installing the inlet, either way. Be sure to mark all hoses somehow, masking tape, colored zip ties, marker, etc, so you don't connect them incorrectly when reinstalling. The two hoses on the boost solenoid are easy to swap if not marked correctly. That mistake added another 30 min. Also, after reinstalling, be sure to check the BOV to intake manifold vacuum line on the firewall side of the manifold did not get disconnected during the process. This happened to me and caused a rough idle and P0171 CEL. It was not a hose that was part of the install, but got disconnected from moving the electrical harness out of the way. So had a nice mysterious vacuum leak for a day after the install that was tricky since it wasn't a hose I messed with initially. Once reconnected, engine ran normal and no code. If you have a good set of tools, have experience knuckle busting, and remove the power steering pump first, I can see this install taking no more than 5 or 6 hrs. There is a noticeable acoustic change from the inlet when driving. Not significant, but noticeably different spool up and spool down airflow wooshes. Just sounds like the car breathes better. I have the COBB turbo back exhaust and am running stage 2+ AP tune. Have never had the car dyno'd so no data on performance before and after inlet install. Am glad I installed this. Did not have to trim anything. It fit as is. The OE inlet hose had cracks and holes at the clamp side as commonly reported by others. This one lasted 8.5 years but wanted the Perrin upgrade. Glad I installed it. Recommended. Enjoy.

    Easy Replacement 2 years ago
    5out of 5stars

    I had already replaced my inlet hose with one from Tomioka for my 08 Legacy Spec B, and I started getting a vacuum leaking about 2 months later. To begin with, the Tomioka was a pain to get in, but my problem was that the insert for the BPV hose had pushed out as I was putting a clamp on it, and the connection is difficult to get to (under the intake manifold). Turned out that as it kept pushing the insert out, it was ripping the silicon and tore a hole. I replaced it with the Perrin hose because it had the metal connection built in so I didn't have to worry about it getting torn and one less clamp to worry about. Things I liked: The BPV hose connection is built into it if you're still recirculating air pressure(some inlets have an insert that you'll need to clamp down on under the intake manifold on twice). It came with an insert for connecting to air filter hose (the Tomioka shows it but they apparently don't include it anymore). It was much easier to fit under the intake manifold than the Tomioka, but you'll still need to take off things that are in the way.

    Very Happy 3 years 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.

    QUESTIONS & ANSWERS

    • Q: Fitment  Fitment1 year ago

      Would this fit with a Forced Performance HTZ Green 60mm ?
      • 0 of 0 people found the following answer helpful

        A:  As long as your Green has the stock sized turbo inlet. You can get those with either the stock size, or the big 3inch inlet. If you have the 3inch, you will need the 3inch turbo inlet hose. Thanks!

    • Q: Boost Creep concern  Tomas Franks6 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?  whitesox311310376 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.
