Nice product 6 months ago
5out of 5stars

Just like as espected, installation depends on how patient you are because fitment issues might come up depending on already installed mods such as fuel rails... The routing of the hoses is easy follow the instructions or do it as you see fit (use common sense) in my case was a little different but luckily enough hose was provided. Quality of product is great, as usual from Crawford.

Easy Install 1 year ago

Everything was as described. Instructions were super straight forward. Only problem I ran into were some fitment issues due to having different fuel rails and injectors but it’s nothing a little bit of grinding couldn’t fix. Would recommend

2008 STI Crawford AOS V3 1 year ago
5out of 5stars

I am happy with this AOS. The Crawford installation directions were easy to follow and the video was also helpful. Mounting this AOS on to the air intake manifold next to the turbo is a very tight spot. I recommend taking off the turbo heat shield and unbolting the waste gate to swing out of the way, this will give you the space needed to use a ratchet. Also, don't over tighten when screwing into aluminum, use blue loctite and make bolts snug. Some of the other AOS are hose monsters. I like how this AOS just has 4 ports and hose lengths are not too long. I would recommend this AOS.

Lots to be desired. 1 month ago
3out of 5stars

Installed on a 2012 WRX. The install of this leaves a lot to be desired. First off, fitment of the AOS itself is TIGHT. Its a good thing the mounting bracket is flexible. Second, you might as well order your own METRIC hoses to save some frustration. The 1/2 and 3/8 inch ID hoses supplied are very difficult to fit onto the 13mm and 10mm barb fittings. Lastly, the instructions from their website are... adequate, but could use some improvement. I have no doubt that it will function and do what its designed to do, but for the price point, im pretty disappointed. Its pretty clear that not much time was spent with the fitment, at least for a WRX.

2017 STi 1 year ago
3out of 5stars

I bought this for my 2017 STi. The hose clamps in my 2017 STi are different than the video/directions and significantly more difficult to remove. I highly recommend using hose remover pliers for the hose clamps. A ratcheting box end wrench is needed to mount the AOS to the fuel injector covers. Overall, the AOS is well built, however the installation was unnecessarily difficult due to a poor mounting location, the directions were incomplete/inaccurate for 2017 models, and Crawford was unresponsive to my questions regarding installing the AOS on a 2017 model. Hence my rating of 3 stars. Pros: The AOS appears to be well built with high quality welds. There were no noticeable changes to the way the engine runs after the installation; which is a good thing; i.e. no check engine light or problems. The extra hose clamps, stickers, and license plate frame were a nice touch. Cons: The instructions for the 2015 STi aren’t accurate for the 2017. If you plan on installing this on a 2017+ STi, recommend reading this: http://www.iwsti.com/forums/diy-mods-and-installations/298594-crawford-v3-aos-install-2017-2018-stis.html The mounting location of the AOS sucks. Access to the mounting bolts are extremely tight. A better solution would have been to mount the AOS to the adjacent sound generator mount, especially since the sound generator is removed as part of the AOS installation. Also, the provided intake plug (to fill the hole in the intake tube after removing the sound generator) looks nothing like the one in the video. It's a cheap piece of plastic that was crushed by the stock clamp and being squeezed out of the intake tube...which would allow air into the intake tract downstream of the airbox and the mass airflow sensor. Will be purchasing a sound generator delete kit. Other thoughts: I use my car as a daily driver. Although my car only had 2,000 miles at the time of installation, there wasn’t any oil in the intercooler when I removed it. Overall, I’m happy that I installed the AOS for peace of mind. However, if I had to do it over again, I would buy a AOS that is easier to install, especially since oil doesn’t appear to be a problem.

Might as well light your money on fire 2 months ago
1out of 5stars

I have a Crawford V3 AOS for my STI and it's not doing it's job at the track. I lose about a liter or so after each track session. My ringlands are fine. This oil loss ONLY occurs at the track and I know why. Because of the way the boxer engine is designed, under high-g turns your oil is going to get pushed to the sides, into the heads, and get sucked up through the valve cover vents which are connected to the turbo inlet. I looked at how Porsches handle this problem and their boxer engines come with an AOS stock. If the Porsche AOS breaks they get massive oil consumption and smoke coming out of the exhaust. Anyways back to our boxers: take a look at the black Y pipe next to the TMIC. If you follow the plumbing you will see the two valve cover tubes on either side combine via the metal Y pipe and connect to the turbo inlet. The turbo inlet is always going to be under vacuum so any oil that makes it to the valve cover vents will get sucked up into the turbo, through the intercooler, and into the engine. We all know that is bad. Before the Crawford AOS I had an oil catch can plumbed between the valve cover breathers and the turbo inlet. This thing filled up after every track session. I thought the V3 AOS would fix this and I wouldn't have to worry about draining and emptying the catch can anymore. I was wrong. The way the V3 AOS is plumbed it does not even touch the valve cover vents. It only handles the PCV valve system in the middle of the engine. Furthermore, the Crawford AOS is designed more like 2 catch cans stacked on top of one another that don't even have a drain. The lower barb in each chamber functions as a "drain". On the V3 AOS there is no separate path for the oil to drain out of like other AOS systems on the market. This might catch oil mist in the PCV system but does NOTHING for the most of the oil that will come out of the valve cover vents. I wonder why Crawford is now a former vendor on NASIOC. 🤔🤔🤔
