335i intake

Well I want to do a minor mod that will give me sound and performance. Now I've never had a turbo'd car before so I'm not familiar with the e92 circuit of products. What is the best intake for a 335i coupe?

ok... well no intakes out yet and they wont make one for a while because its a turbo car so the intake isnt important and a bad made one can lose HP... the one BMW is actually really good... u might wunna get an exhaust or a muffler for that sound and some HP but noooo intake

yes, the factory air box is acutally pretty good, the air filter has a pretty large surface area. I would recommend swaping the exhaust system instead.

I disagree in that an intake is more important for a turbo car than a naturally aspirated car, but until someone releases one or does some dyno testing comparing stock to no air filter it's not worth messing with.

Well I agree, on my e90 I bought an expensive Eisenmann exhaust and the money was ridiculous. My favorite mod is exhaust and it's soo much money to buy a brand name exhaust. Is there any way I could go the route of custom exhaust shop, what are my options as of now?

3 words...........Turbo Back Exhaust............it has to be from the turbo back for the true performance, maybe a nice 3 inch down pipe also when it comes out......

Well, I have a 2.5" prototype unit on my car.
Center CAT delete and 12" perforated resonators.
It's gotta be making about 25whp with stock DPs.
I easily break my Toyo's loose in 2nd now and also pull a full car length on a stock 335 from 20-90mph.

I'm probably going to dyno her this weekend, but yes...........

With a full back, hi flow DPs, she' easily make another 30-40, as the stock DPs are restrictive.

We'll have a full back system soon enough and it'll really make the car quicker !

How much you think an exhaust you think for this car will go for?? Can you PM me with the price if I forget to come back to the thread, thanks

Nice, this all sounds quite pricey though.

Just because its a turbo car doesn't mean that they can't come out with a better intake for it. If something was available that made the same power as stock, but sounded less restrictive I would buy it.
