The ERMM(what I put in my car) makes a world of difference in terms of response. The slop of the original RMM is replaced with a balanced connection to the frame. So you will be quicker because the engine torque is able to transfer to the wheels quicker. Not necessarily by a bunch but it is noticeable.
The drop in filter with the ERMM and snorkel delete are still the best $100/bang for the buck you can spend on this car.
I did the snorkel delete and found that there was a louder sound and it felt smoother. This was done in the summer time. Once winter hit I noticed that it wasn't all that great and I had issues of noticing that while engaging from stop to first gear it wasn't as smooth. I don't know how the seasons would make any difference but when I put the snorkel back on the car felt smoother. I have no other mods. I doubt there are any hp gains from this upgrade other than added noise.
Also this is not a hard upgrade job to do. It took me 10-15min to put the snorkel back on and all I had used to do the job was 1 flat head screw driver and a flash light. I was by myself and it was night time.
I personally prefer the less noise when I give the gas after having the snorkel off for 6 months.
Hello FoFo Fanatics!
Lurked for a month or so, read this ENTIRE thread the past few days; tons of knowledge here, likely too much for my brain to soak it all in. I definitely want to do this. Thinking I'll get the ST intake piece as well (peace of mine/mild aerodynamics, mostly).
Now I'm a complete noob when it comes to cars; this is my first car, and I haven't done anything to it. Only a few things I'm really wondering/concerned about:
1) does anyone have a video of how the AEM (or any closed filter, I guess) sounds? I have seen videos of the open-end Green filter and want to compare how they sound.
2) I'm aware closed has more benefits, but the "fun factor" of the open end may be appealing sometimes, so I'm considering the K&N that I can pop the cap on/off for. How difficult is it for a beginner to re-apply the oil to the filter itself? Alternatively, is this something the dealership would do?
3) Is putting in a filter/deleting the snorkel going to screw over my warranty? I know it was gone over briefly, but I think that was just the snorkel and not the filter.
Cool, thanks for the info guys. I'm thinking I may go with the AEM filter; listened to some videos of other closed filters and they still sounded pretty loud (but also pretty nice); can't imagine wanting to go much louder.
Will also need to have a look about getting the ST snorkel. I don't really like the idea of leaving it just bare like that, and 5 bucks is a low price to pay.
Either way, looks like it'll all have to wait a bit; it started snowing here after such beautiful weather. I hope not many people here swapped out their winter tires...
Sorry to be a pain, but is there any huge benefit of the K&N over the AEM Dry Filter? I am not experienced with car things like this at all, so am somewhat wary on doing so; don't want to break my MAF or other components (though I guess the instructions are likely pretty simple).
There's also that on Amazon.ca, the price difference between the AEM AE-20993 and the K&N E-2993 is about $30... The K&N E-9289 is another $10 (so $40 from the AEM). Haven't really looked locally with the weather as it is. Thanks again!~
Changing STOCK air filter is no different than changing any of the optional ones, MAF is down the intake tube a bit from the intake box. Just cover the hole with a draped rag if leaving the filter off for a while in the process and don't shove anything down the hole.
Sound won't change appreciably with a closed box between filter types/brands, only when you take the top OFF or use an open end style filter (only opens to additional filter area, NOT wide open).
Got the new OBX header for my MK3 18 S installed today. Was easy up until I had to join the flex pipe to the exhaust. I think I might have either tugged too hard getting the pieces together and knocked something around, or when I removed the OEM header I might've pulled a heatshield or...
I know this has probably been asked a million times but going to ask opinions on exhaust. I have a 2014 SE sedan, and I'm considering doing something to my exhaust. I'm asking for first hand experience on a few avenues I'm thinking about. What I'm thinking about is the FSWerks Stealth...
Hi there! I was wondering if anyone in the community had suggestions for a exhaust for a 2018 Titanium Sedan with the DCT transmission. I'm looking for something not too raspy and with minimal drone. Ideally I would like some kind of touring exhaust that's a little louder then stock when...
I am going to show step by step pictures , description with building a MK3 Engine , Making the Custom DIY Turbo kit , installing LSD , and Clutch
I want to keep this to the information about the MK3 engine , I have been given a 2013 Focus and an open check book to build this any way I want to...
Got a set of OBX headers for my 18 MK3 focus that came with an OBX gasket for when you install. However, I seem to have misplaced it.
Tasca has an OEM header gasket for $6 or so.
Will the OEM header gasket work with the OBX headers?
