REVIEW: Mishimoto Performance Intercooler for 335i--NOW WITH LOGS

Hey guys,

So I was the one who won the Mishimoto intercooler contest on this forum a few weeks ago. After exchanging some emails with Mishimoto and talking with their forum representative, they are all very nice and easy to work with!

This intercooler is being installed on my 2007 BMW 335i coupe. Other mods are:
-VRSF DP's
-VRSF Exhaust
-cp-e DCI
-stage 2 custom tune on OFT

I receive the intercooler last week and did the install myself. The intercooler came packaged just like below.

Here are some pics compared to the stock unit. The Mishimoto intercooler is deeper but the same height as the stock unit.

I got my car up on jack stands and assembled the tools I'd need to complete the install. I used the following:
-8mm socket and ratchet
-T25 torx bit
-flathead screwdriver

I glanced at this video that Mishimoto posted about the DIY install to make sure I knew how to do it. This is my first boosted car so I had never done a FMIC install before.


The install was extremely easy and very straightforward. From putting the car in the air, until it was back on the ground took me approximately 30-40 minutes. The best part was that I didn't need to trim any plastic or anything. The intercooler slid right into the factory spot with no issues!

Here's a picture of it installed:

As you can see, this intercooler does use the factory pipes and connections which made install really easy. Basically unbolt the old one and undo the clamps, pull it out and then slide the new one in. Ignore the grease mark on the endtank, I was helping a friend with their car as well and forgot to wipe it off before taking the picture.

After getting it installed I waited until that night to go out and do some pulls. I've been running a stage 2 custom tune WITHOUT an intercooler since last fall so I'm well aware of how the stock unit begins to restrict power after as little as one pull. After getting this intercooler installed I could immediately tell a difference in how consistent the power was pull after pull. I did 3 3rd gear pulls in a row immediately after one another and the power felt consistent with each one. I went on to do another 8-10 pulls over a 3-4 minute time span and didn't encounter the power loss that I had before. It feels as if the car doesn't begin to fade towards redline as much either. There is also a good power bump as well. I don't have the funds for a before and after dyno but I'd say that their claims of 20+ HP are accurate.

Overall I am very happy with the intercooler! Install was a breeze, and the gains are very noticeable! The fit and finish are 10/10 in my book. I had no issues with install or getting things to line up whatsoever. Mishimoto was a pleasure to deal with as well. Very nice and willing to help with anything that I needed. Very good product and I recommend it to anyone who is shopping for an intercooler!

If you guys have any questions or want more pics just let me know and I'll post them here.

Nope like I said in my original post, I don't have the funds for dyno sessions or a place close by.

I've never dyno'd my car for any of my mods.

Will you be logging IATs/timing? I assume since you've been stage 2 since last year you have logs with stock intercooler as well.

Awesome , must have been a great feeling to win that contest. The mishimoto looks very solid and we'll made. I had my doubt as fsr as the size, but the side by side pic helped. It looks bigger and is probably a lot more efficient. Keep us posted.

Ok so I just uploaded a new log.

Pre-FMIC---
This log was taken back in Feb since all my newer ones dont have IAT on it since I was looking at knock and WG stuff instead. This one was in the middle of refining a custom map so it's not perfect but will give you guys an idea.

Temps were around 30* outside.

Post-FMIC---
Here's the one I just got. Temps were 70* outside

If you don't already need a new clutch, you might want to enter a tire contest next.

Look forward to talking soon.

I was wondering if it could be possible to use non stock silicone hoses on it if someone decidedes to use a different charge pipe after having mounted this fmic.

I would assume so. Or just get one that uses the c-clip like the vrsf one. Charge pipe is next on my list so I need to look into it as well
