@jbeatzs31 what filter is that? Green? If so, are you running it with the end still open? (Can't tell from the pic) And what's the benefit to running a vented oil fill cap? I remember that back in the hot rod days, but is there any benefit on these motors? Wonder how doing that interacts with the PCV system? (Sorry to change gears on the thread)
I just ordered the rs box also. not sure why people are hating on st owners that want to run the box. it's a better setup than stock that happens to say rs on it. for 50 bucks why not.
Technically the only cold air intakes for our cars are the snorkle add ons. Ford even calls their snorkle a cold air intake. These pull air from outside the car not a fender or engine bay.
save your $$......I made a custom "Roush type" one by simply cutting the top of the stock box top and adding a heat shield along the top of where I cut......some other guys on here did as well. But I ended up just going back to using the stock top and fabricating a heat shield on top.....actually indents the hood heat shield. As good as you can get......intake mods are really for show with this car.
adding a BOV to a car with a draw through airflow meter will cause the car to run pig rich, if you want more turbo noise run and open intake box with a KN or other high flow air filter
you'll have the turbo noises that you are looking for without being obnoxious and looking like a ricer, an aftermarket bypass valve(mountune makes one iirc) should also add more sound as well, i remember when i switched from the stock bypass valve on my eclipse to a GFB evo9 adjustable valve, keeping it at 100% recirculation made my car sound like it had a HKS SSQV BOV so i imagine an aftermarket BPV for this car would do something similar
I have the AF Dynamic intake off amazon for $160. Simple to install and looks like every other cai for double the money. Came with the same metal shroud as the injen setup but i hate how it blocked off the air inlets from the front end. So i cut my oem box to accept the new tube. Love how it looks for the money
I have just the RS lid and even though it is as quiet as stock I like the looks, I took the ST badge off the trunk and overlayed it on top of the RS logo. Looks fine to me and doesn't require much effort.
eh?? wth that looks like crap!!! I can see the RS sticking out around the ST, might as well have the glue bulging out from under the sides too... holy fkn ghetto setup!!! lol
I'm looking to do my first few mods and was considering the intake. Are the snorkels like the Ford Performance really not of that much benefit? I gather the IC will cool the air enough in stock form that an intake really wont make a difference?
I'm a major newb to turbo cars and am studying these threads to learn.
Hi Dave, welcome to the forum.
This is just my opinion but I believe the coldest air intake you're going to get is with the closed lid stock box with a snorkel. Reason: The stock box is keeping the most engine bay heat out with the closed lid and the snorkel is sucking air in from the coolest place possible (front of the grill), plus at speed it's acting like a air ram. I would upgrade the intake tube. Again, these are just my thoughts and I might be way off opped out:
Mountune seems to think the RS airbox is designed to reduce pressure loss, however there was an article in carmagazineuk that stated Ford engineers designed that open section which seals to hood for when the car is running with the hood/bonnet open like on a dyno. I think if you run a snorkel you need to seal every opening (stock lid, closed-end filter) for maximum functionality.
Just installed RS airbox on my 2018 ST3, also added the Ford Performance Badge over the RS logo, like the above one with the green filter above. Next will be the AEM filter to replace the stock filter! Want a closed filter end not a open filter end like the green.
