 Today's Cobb highlight is the version 2 turbo inlet hose for several of the EJ powered Subaru's. This highlight video is a 2 for 1 special. We've got updated designs for two different families of EJ cars. This one is for the 08 and up STIs and its brother here is for the plastic manifold EJs which is the 05-09 era legacy and outback plus the GRWX. But we'll mostly talk about the STI one simply because nearly everything we're going to say applies to both, so no need to say it all twice. These are stock replacement parts so it can be the very first mod that you make. The two main reasons why people replace them are because the stock one fails, which happens a lot, and to improve the performance and engine bay appearance. The body of the hose is made from a steel wire reinforced multi-layer silicone. It starts with six layers and maintains that most of the way through but it does drop down to five layers right at the end so it's super sturdy through the entire piece but just a bit more flexible and thinner when trying to slide it onto the compressor inlet. We actually tried to see if we could get it to collapse from the vacuum created by an upgraded turbo which is a genuine risk when cranking up the power with an inferior inlet hose. But we had a 2011 STI on the dyno using this inlet making over 500 horsepower with no signs of collapse or any other weakness. Speaking of which, it is a 2.4 inch internal diameter so it's designed to fit a stock turbo or a stock location upgraded turbo. Moving on, these two adapters have been completely redesigned since our version 1. They almost look plastic at first glance but they are in fact billet aluminum that's been anodized black. The OEM is just weak plastic and the old version 1 carbon that was steel with a bead roll so this billet design looks a lot cleaner and is even stronger. Plus the bead to hold the clamp in place is machined from the outside so the inside adapter is 100% smooth with no indentation that you would get on a bead roll pipe. Aside from the actual materials used to construct them, there are several other nice benefits and design features over the original or stock version. First, it's friggin big. I'm sure you can already tell but it has far more total volume throughout versus stock or any of the other aftermarket versions that I've seen. And that really does help performance. You're not going to see massive gains just from a turbo inlet but we have seen legitimate and repeatable increases in power specifically due to changing this part alone as it reduces pressure drop before the compressor housing and that improvement on the inlet side has a direct benefit on the hot side that helps with spool time and throttle response. Another nice improvement over the version 1 is a cleaner and more simple setup of the vacuum lines and ports. Everything matches the OEM layout perfectly so no teeing off lines or getting things mixed up. It all just goes back where you originally disconnected it including this bespoke connector we made for the PCV. It just plugs in exactly the same way the OEM connector works. We even made the effort to find high quality barbed fittings for the other ports that are shorter which gives the entire unit a smaller profile to look cleaner and help with install. On that note, usually installing one of these things can be a big pain in the butt. Typically the best option is to actually remove the entire intake manifold but even with a much larger size we managed to design this one so that it can be installed without having to remove everything around it and we've had an experienced tech do the entire process in less than an hour. All in all swapping out your turbo inlet is or should be on the to-do list for anyone looking to modify an EJ Subaru and there have been some good options out there on the market for a while but in my opinion they were all a bit lacking including our own original but not anymore. If you're running a stock or stock location turbo with a 2.4 inch compressor inlet these version 2 cobb inlet hoses are the best looking, best fitting and best performing options on the market hands down and the only one you'll need until you want to get extra rowdy and go to a much larger turbo.
