Intercooler upgrade question

MK335i · 03-17-2015, 11:32 AM

Is it worth upgrading the FMIC? I have the DCI upgrade but I hate how hot these engines seem to run, especially in the hot summer months that are coming up.

I'm running COBB stage 1 Aggressive which requires no upgrades.

Just trying to get some more airflow in there and wondering if its worth the money?

Absolutely worth upgrading the FMIC. The IAT on these cars heats up super fast during a WOT run due to the inefficient stock FMIC. Do a datalog and you'll see.

Yep! Stage 1 + FMIC is a faster map then Stage 2 for just downpipes too.

The stock intercooler is inefficent even on a stock tune car. FMIC should be everyone's first mod.

I just did mine over the weekend. Was fbo minus fmic for 5 months and got used to the heatsoak after the 1st run or so.. Flooring it now back to back runs gets me kinda scared thinking something isn't right lol

Absolutely . The stock intercooler is one of worst components of this car.

Just went FBO 2 weeks ago....it's ridiculous what Cobb stage 2+ FMIC Aggressive is compared to stock.....over and over again...consistently brilliant. Need to catch up with you next time I am in the Ville...

No question, I just did 7 VRSF, really cooler IAT on pulls.

Great mod for the 335. I also opted for the 7" VRSF and its a great product.

Tiago@VRSF · 03-17-2015, 10:07 PM

An intercooler is hands down the best mod available for this car. The OEM intercooler can barely handle the stock turbos and REALLY struggles once you increase boost pressure.

I just had a hard time believing it's a 45min job.took me 5hrs to trim and all. Stupid piping and elbow wasn't being fair

Depends on how experienced you are with intercooler install.
First time should take around 2 hours.

I'm not a expert but can work on cars. Took me 1.5hr to swap out the water pump and t stat. I just think the 7'' is little to big for the small openings even after trimming, and explanation on removing the stock connectors wasn't good either.
