[MichiganBMW335i]

Hello everyone

I am new to the forum and just bought 2007 BMW E90 335i with an AT and sport package. I am looking to do some modification the the preformence of my of my DD. I found that my car was part of the original 07s that did not get the oil cooler (preatty pissed). I tried to talk to the BMW NA to try and get it retrofited and they told me that because I was not the original owner there was nothing they could to.

List of mods I want to get. Any thoughts on what kind or where to buy would be appricated.

Oil cooler
Intercooler
JB3 2.0
Exhaust

go to your regional forum...

See what guys in your area think/run/where they get it from.

I can tell you from living in the midwest myself, the oil cooler is only really necessary if you plan to track the car. For a DD and occassional hard runs, you will be fine without it....and your oil temps will only concern you on a few of the worst days.

Otherwise your short list is fine. Have you considered upgrading your wheels and getting new non-rft tires? Also, gonna need a winter setup if you plan on driving in the winter....the all seasons are OK, but proper winter tires will be much better.

Also, since you are in the midwest...WSTO is our preferred vendor for almost everything:

etc, etc, etc...in fact just contact WSTO give him your credit card, take the bills and burn them. Do not open.

I don't see why everyone thinks that by adding HP it improves the car, lol. If you really want to see an improvement in the quality of your car, I would 100% do suspension work and an LSD. Get coils or M3 suspension parts and an LSD. Neither will void warranty (well shocks and spring warranty will void but the M3 parts are covered by BMW) and you will see a DRAMATIC change. And of course wheels and tires. Good luck and have fun!

DD = basics. The "JDM" fundamentals would be:

Intake, exhaust, springs, wheels.



Then... Tune, DP, LSD, coil-overs, roll bars, BBK.

I would also recommend going with suspension and wheels. I did some Koni yellows with H&R springs and it has made the 335 much "tighter". I would do a tune after a few months since you should get comfortable with the car. Once you get bored with the power, throw on the tune and you will be amazed. Finally, wheels and/or tint are great to transform the look of your car. Swapping out to non-run flats will instantly make your car perform better. If you decide on wheels, let me know. I am selling a set of BBS-CH 19' rims with tires and I am drive in your neck of the woods quite frequently.

Currently I have the stock 18 inch sport wheels with continental DWS's and have a set of blizak tires for the winter. Also when I bought the car it already had tint all the way around. I would like to get newer rims. I would like to get a 18 in version of the M3 wheels. i dont know if i want to go to 19 in with the roads and pot holes in michigan. I also would like to do a LSD but that will probably be a little later. I want to do at least exhaust by the end of the year. Do you think that a CAI or different intake (AFe) is worth the money over the stock?

Regarding the intake. I've heard different arguments. I can tell you first hand that while on a dyno we ran my car with the hood open and then closed it and the negative impact of closing the hood and restricting the airflow was dramatic. Also, due to placement, heatsoak becomes an issue. So, I don't think an intake can hurt, but honestly, in terms of bang for your buck...that JB3 or other tune is gonna have the biggest impact. Everything after that is incremental.

I'm not disagreeing with everyone's assessment of the suspension components, I think that is important too...note I'm running KW2's and aftermarket wheels/perf tires. But as a daily driver, unless you are taking alot of twistys or hard turns...you will feel the effects from the tune more on your butt dyno than you will notice the upgraded suspension.

In the end, do them all to your hearts content, it's just what priority. If aesthetics are your concern, def wheels/drop. If going fast is your priority, tune/exhaust.
