BMW N54 335i Upgrade 5" Intercooler Install – FMIC DIY: MHD Stage 1+ Build

Dylan keeps wanting to make his relatively stock 3 series BMW faster, so today we added a cheap front mount intercooler upgrade which will allow us to run the stage 1+ flash from MHD.

Very impressed with the results from such a simple / direct replacement modification so we do highly recommend it. If you want to grab one with our affiliate link check them out here https://ebay.to/325ZY0l

We didn’t get a chance to flash the car in today’s video so we will have to get it back for a 2nd video and in that we can do a true speed comparison for the stage 1 Vs stage 1+.

What's the reasoning on covering you license plate information because when you driving down the road people can see it but cant get any information from it because its not accessible to the public.

Greg Wayne says:

I wanted to thank you guys for the tiny little mention you did about the small plastic square in the corner of the right side where the cooler goes in. If you hadn't mentioned that I would have continued to believed the guys that keep saying in their videos that it just "Goes right in no problems and that's it". So when I started having trouble getting mine to go in I remembered what you said and realized that little plastic piece comes out and is the problem. Big thank you!!

Yo, 0-60 guys. Going race style with my 1M and it’s tight in there. Dynamic Autowerx high flow plus going in. Have a csf fmic now but considering the Vrsf 7.5 race one. What’s your opinion on this being the right one? Thanks

Hey guys, thanks for the great content as always! I was hoping you could answer my question. I am looking into upgrading my intercooler, and therefore have gone back to re-watch this video. Do you think that I am better off getting a similar size cooler with a bead on the end pipes so I can upgrade the stock piping later, or you think that this cooler would allow for aftermarket piping to fit later without modification? I am thinking that silicon pipe might be a better future alternative to the stock plastic S pipe. (I wont be running more than stock turbos.) Or would you just stick with the stock piping? (I know its a direct fit on this particular intercooler) thanks again. Regards Chris.

Did you reuse the standard bolts that came with the old intercooler?

顏可銘 says:

The intercooler looks good, I like your video, I have a e93 335i too, just plan to upgrade my intercooler, I into your link to ebay, is the size correct for stock hoses connect? Cause the pictures show the size like 81mm in, 70mm out, just worry about can’t fit for stock, have you give any problem for boost leak?

Greg Wayne says:

Edit: After I wrote this I realized I live in Canada and that may be why I had the results I did. Our summers only have a few weeks at most where I live of +30 temps. Sooo…. End Edit. Okay a few years ago I had my 2008 335i N54 tuned by a tuner. All they did was check that I had a factory oil cooler and then put in a high flow K &N air filter asked what Octane I was going to use (94). Put in new plugs and they tuned it to 389 HP and 412 ft-lbs torque. This was their Stage 2 tuning package. I ran it that way for three years with only changing my coils and plugs once. I drove it like I stole it then sold it with the tune still installed. No bigger FMIC or Down pipes. Mind you if I had wanted to get their Stage three they said I needed down pipes. But no talk of a FMIC. So I don't think you really need the FMIC for the Stage 1+ Tune from MHD. IMHO.

On the right side the O ring they give you is too big, I had to change mine and it seated perfect

badboygto says:

Ben M says:
