I’m thinking about getting a 2015 focus ST as a daily driver soon. Are they reliable? Are parts hard to find or fix yourself? I’m mixed between the FoST and FRS and if it isn’t reliable I’m probably gonna lean toward the FRS. The 4 seats, hatch, decent power, and good looks make me like it a lot. Just wanna hear from a couple owners since it’s a 10 year old car.

And the socket and the lug lived happily ever after...

My ST came with a busted up CPE intake; the whole front box is broken and I've been temporarily running a specter air filter on it because the one that came on the car was completely trashed, with holes, letting dirt in for who knows how long.

I'm not a fan of oiled filters or aftermarket filters in general because they are substantially less effective at cleaning air. I don't really want to get into any debates on this topic though.

My goal is to build a new air filter box from sheet metal, and to rig up an OEM paper media air filter to the CPE pipe, as I have been unable to find any aftermarket paper media conical filters anywhere.

The CPE pipe is 3" but the box mount that comes with them requires a filter with a 4" inlet.

Does anybody know the inlet size for a stock air filter? I can't find the spec listed anywhere. And it looks like you should be able to fit a hose clamp on the flange.

Basically, I want to order whatever reducers and couplers I need to be able to mount a stock filter on the end of this pipe. I'm thinking the stock filter is around 2.5 or 2.75" but I need to know which one. There are plenty of 45 degree silicone reducers for 3" to 2.75 or 2.5" pipes, then I could get a 2.75" coupler to put on the end so the filter can mount on.

First post: Sooo basically my driver front suspension has been making a creaking noise recently any time it bounces (bump, general change in height, etc) and its also been doing it when I turn most of the time. I have BC racing coilovers and megan racing sway bars and links. I replaced the control arm at least a year ago and I forgot what else, but the only aftermarket parts there are the coilovers and the sway bars. I'm fairly well versed in mechanics I just dont want to spend hours looking at the wrong part this weekend if its something I can easily fix. The video is mostly from me turning since I can only upload one video at a time but you get the idea. Turn it up a bit to hear the creaking. Thanks yall!

Hey all, as some of you may recall, I went to colorado a few weeks ago and was in a car show at PPIR. On my way back, I hit a road gator and now the passenger foglight, housing, and bumper mount are broken. I prefer the pre-facelift bumper, but I am open to getting a facelift bumper. Does anyone know the best way to go about getting one?

Note: there are only base model focuses in the junk yards near me

No intercooler is saving me😂 Heat-soak is bad enough with a cvf intercooler I can’t imagine how bad it is with the stock one.

Can’t wait for winter and my big turbo🥶🤙

Really not sure, just noticed it was worn down, never noticed a problem with anything in the car

I have replaced reservoir and cap because of hairline cracks, the notorious heater core hoses which weren't leaking, The water pump which was weeping, changed the thermostat housing to a metal one, and my car is still losing coolant. Im guessing its a high heat and pressure coolant loss as it was pressure tested by a shop that works on ecoboosts specifically and to no avail I still am losing coolant. No visual dripage so my next guess would be the radiator return line or the radiator or maybe I'm wrong. But the shop basically said that they couldn't find any problems, my car doesnt spew white smoke that would lean toward a cracked head... so not sure what to do at this point.

786 mile trip later! Pretty pleased with the MPG but surely could be higher as it started at about 16 MPG. No issues so far (knock on wood) and I am loving every minute spent in this beauty. Cobb port soon and then let the real fun begin. Also any suggestions on an aftermarket stereo? I have the Sync 1 so I’d like to get a head unit with apple carplay. OEM is a bit too pricy for me. Any trustworthy amazon units out there? Thanks!!

I'm being asked to go back in after having the pcv replaced under a Ford customer satisfaction claim to have the PCM reset I believe. This all revolves around the tank deformation issue. Anyone know if having a tune will be an issue ? And has anyone else had these recalls covered that can tell me what they got for parts and service from it?

Lights used to show an error when set to auto resulting in the left headlight pointing down to the left. They would work fine beforehand for a few minutes following the steering etc. now the error is happening when they’re just set to on. Sounds like a stuck motor?? Any ideas. All wires inside look intact

What sealant should I use to mate the two halves of the transmission. Had to drop it again for a failed slaved cylinder and might as well seal it again because it has been leaking.

Trying to figure out what my best TRACK FOCUSED coilover option is for around $2000.

I’m currently looking at fortune auto 500s, silvers Neomax w/swift springs, bc racing RM series w/ swift springs, or red shift competition coilovers

This car is NOT a daily, at most my girlfriend will take it to work once a month so it doesn’t ever sit for too long. The entire purpose of this car will be for AutoX and HPDE events at a local road course. Planning on doing at least 1 event a month

No I do not want bilsteins and springs, I’ll be choosing a custom spring rate for whichever coilover I go with.

Info from anyone who heavily tracks their focus would be awesome. Thanks!

3 months after joining the community, my FoST journey was cut short after my petrol MP275 ST was stolen (picture 2). It was a financial hit and a tough first experience of theft, especially given the car was so new to me.

I had to leave this subReddit because it was too painful to see you all modding, driving and enjoying your cars.

😈😈 I had an opportunity to pick up this top spec ST3 and I’m proud to say I’m back in the club.

Sadly, it is the TDCI - it’s still a heap of fun, but it’s crying out for a remap and feels like it’s got plenty more to give.

18 inch wheels drive SO much more comfortably than the 19, sync 3 / car play / cruise control is game changing, heated seats / screen / steering wheel makes me feel fancy, and I’m disappointed in the Sony sound system.

I’ve got some boost hoses and an intake on the way, a stage 1 ecu map and I think she’ll be just fine for me.

Any other TDCI modders willing to share their 2 cents?

These photos are from my first event, since then I’ve got 2 wins and a 3rd place in class the car handles amazing and autocross has made me appreciate it so much more. here’s some footage from one of my events https://www.youtube.com/watch?v=wr-CeK4atqY

I am curious is this fine like this? Both the downpipe and exhaust are 3 inches but the flanges where they meet are different sizes.

Anyone got trailer hitch recommendations? Looking to get one installed for my move back east. PFA

I have been noticing some weird popping from the exhaust immediately after clutching in to shift, usually around 3k+ RPM

I checked the fuel trims with a buddy's scanner and the long term trim was at a +9% while the short term trim was bouncing between -5% and -18% depending on RPM

I figure I might swap the CPV just because I purchased the car at 13x,xxx and it is now around 150,000 and I have no idea whether its been done at all.

Outside of that, I'm not sure what else to look out for.

Any advice or tips would be great.

Flirting with the idea of replacing my 2010 Outback 3.6 with a similar aged MK2 Focus ST. Pretty much all for experience reasons, 5cyl noise, manual transmission, "slow" car, fast fun.

There are none in my area I can go check out so just want to know how the cars have aged, with particular interest to the interior. How's the fit and finish, have the plastics held up. Has it become a rattly shit box or is it good enough - I recognize this is going to be a step down in comfort and fit and finish over the outback but just trying to get a gauge of how much, if that makes sense.

Anything else a prospective owner should be aware of apart from the cylinder walls cracking?

Went up a size. Feel great. Kinda want alil bit of spacer now 🤷‍♂️🤨

I'm sure it's not hard to actually change, but all I have are ramps and it's kind of in a hard location to get to. Any tips, or should I just go to an exhaust place?

Im planning on doing the fluid change sometime next month but want to get ahead of the inevitable master cylinder leak if I can. What all goes into replacing it, and is it worth my time doing so? Or just waiting until it gives out. Lmk!
