AVO Silicone Turbo Inlet Pipe Black

Part #: AVO S2A00G41BBLKA


The turbo inlet is constantly under vacuum. It's common for people running more than stock boost levels to collapse their turbo inlet. With this AVO turbo inlet designed for the 02-07 WRX and STI this will solve your problem or prevent it from happening. This wire reinforced inlet is extremely strong to resist collapsing.

Another key features is the built in post MAF hose, making this a great product for anyone who is looking to replace both items with just one product!

The build quality is obvious immediately, and the installation wasn't too bad (let it sit in the sun for bit to soften up). The only problem i had is that the post-maf part is a bit long and is stretched onto my airbox to fit (could probably just trim it to fit better). Makes a nice increase in sound as well, and after getting it tuned for I'm very happy with my car.

Very nice product, a little snug of a fit under the intake, and didn't work completely the way I wanted to with my FMIC but I got it to work good

got this piece yesterday for my 06 sti and was doing a ton of reading and was worried it was going to be a bit$* to install. got home today installed in an hour and 45 min, WITHOUT removing the intake mani. advice take all the nipples off the inlet before proceding to shove it under minus the bov metal piece, also take off the power steering hard line like the instructions say which is a big help. the part most of you are going to struggle with is getting the lip on the turbo and thats where an hour of my time went :/ i used two flatheads with a little bit of electrical tape, and worked my way around it. Be patient and it will come along. Overall i am completely satisfied with this piece makes turbo spool louder and quicker, which i noticed with my front mount. recommended to everyone looking to forget removing there intake mani and good quality piece. good luck!

Great inlet! Yea, the install is a little irritating, but it's worth it. If you're considering an aftermarket inlet, this is it.

Well made

I am hesitant to give 5 stars due to fitment. I can't knock it to 3 stars either. This was installed along with 3mm phenolic spacers, so it is possible that fitment would have been perfect with normal IM gaskets. The piece is well made and doesn't appear flimsy. I like that AVO moved the location of the normal vacuum used for the PCV. This makes installation and routing easier. My PCV is deleted and I am runnning an AOS, so it was ever better for me.


  • AnswerQ: AVO fitment  mattmontalvo03676 3 years ago

    I have a COBB stage 2 tuned 2003 WRX sedan on the ACN91 301 map. I am installing a newer turbo on my car, possibly some TMIC silicon hoses and a new PCV valve so there will be a lot coming off of my engine already. I wanted to grab this and was willing to take off the intake manifold to install 3mm phenolic spacers and possibly to a TGV butterfly delete as well. I already have a grimmspeed AOS installed per grimm's recommended installation if that makes any diff at all. Here's my question: does this hose have all stock sized inlets/outlets/nipples? I want a hose that is dead stock sizing wise but doesn't deteriorate over time with oil exposure like the stock inlet hose and doesn't have the baffled crappy air flow of the stock MAF. Is this the solution for me? or is the hose sizing larger causing the need for a product specific tune?

    • A: Hello, Yes, this will be a direct replacement for your stock inlet hose. Everything will hook up just like stock. So other than the time it takes to do the install, it should go in without any issues at all, and of course be much stronger and last longer than stock as well. Thanks, Rick
