Here is a photo slide of the cutting that need to be done its best to provide the "PRO" installer this slide so they have an idea if they never worked specifically on an IS Try to get an IC that has no more than a 0.6 PSI reduction Also it would help, for adding more boost later with the Cobb AP, to get an IC that is close to 90%+ volume increase over the stock. This will be alomost two times the size of the stock. Most sellers do not mention this so its best to shoot them an email if you dont see it in their online specs. Qualify the intercooler with the above first then we can move on to the final qualification Intercooler core quality and design is also important. Usually, vendors buy the cores from a core manfacturer and just cloth them with a housing and side tanks etc for the specific car they will go on. If it gets too technical just make a new thread of the options you find so other may chime in. it may turn out to be a grudge match but you will learn from it Keep in mind prepare to hear "cheaper" but have no idea about PSI reduction, volume sze, or core design and quality. All intercooler are not the same. People who believe that just run after the cheapest thing they find inorder to up boost. You have a 60k car, dont treat it like a rice burner. Do it right. |

You really need to be honest with yourself as to what your goals are when choosing an FMIC. If you are not going far into modifications there are quality 5” units that will bolt in as direct replacements for the factory unit with excellent IAT control. If you are thinking about more serious mods then a tune you will need to think of cutting the plastic to fit in a bigger unit.
I would agree that the cheapest is not necessarily the best choice but neither is the most expensive. Try to see what the core design cutaway relating to heat transfer looks like in any cooler you are looking at also the quality of welds, the shape of the end tanks & included plumbing.

There is no 100+ % that is a "direct replacement" for the stock. Only 84% - 93% so if he wishes to get ProTune with Cobb later perhap, even turbo upgrades, his IC will easily accomidate the new power and still run efficient thus he doesnt have to buy another IC in the furture

I have a 2011 IS and went stage 2 pretty quick, but did get a stage 1 run in for comparison. Shoot me a PM if you want more info.
FMIC had a huge impact, stock the intake temps jumped over 160 degrees, but with a helix, the temps never went abovo 100 1 is stage stage 1 and 3 is stock. 100% stock car. Cheers, James

More air volume + greater PSI reduction = better heat exhange coefficient / lower IATs = better timings less air volume + less PSI reduction = not enough heat exhange per the increase of power / higher IATs = more timing pulls So in other words we dont want to go too large nor too small with our tiny stock turbos. Helix seems to be a good 1st candidate, or the HPF Intercooler Last edited by BQTuning; 02-28-2013 at 07:13 PM.. |

I understand why fmic are good for the car, I was simply wondering where you came up with 90% more volume. My understanding would be that fmic don't force more volume of air into the car, but more oxygen dense air by lowering iat. A larger core would simply be more resistant to heat soak and be able to cool more air. Negatives would be pressure drop bc the volume is large and slows down the air velocity going from the turbos into the intake manifold. Please correct me if I am wrong.

No idea but it will get squirrely on a flat road with the traction control off. You can feel it pull much harder as it gets into the RPMs. Like BurQ said, I spent some money on the car and not interested in ragging it out at this point so I'm still a bit hesitant to drive it too hard. Almost tempted to drop back to the Sport map for longevity since I don't have an upgraded IC.

I have ESS on my FBO 335i and I am happy with it. No issues ever!
Unloading and loading of maps is 15 minutes with the flash reader/writer tool. If I was to choose , I would simply go with the one that is closest to you. There is no COBB where I live so the ESS is my only option. ESS is one of those who have been in the 335i N54 world the longest if I am not mistaken. They used to deliver very agressive tunes in the early days , but now they marked only more mild tunes on their standard package online. That is maybe why people choose other tunes over them. Custom tunes is of course available there too. Im going there for a custom tune when I get new turbos and cylinder head. + meth

its on order , dont think any of us who have on order have got it yet. we are all waiting...
And my stage 3 head from VAC is also on order. My guess is that I will start the install this spring then drive to ESS in early summer and get the tune sorted.

Sounds good, best of luck with the system.
