Mein Auto: '11 E92 335is
Stock vs. aftermarket Cold Air Intake

Hey Guys just wanted to get some opinions on going aftermarket CAI. Is there really any benefit to installing a CAI vs keeping the stock one on my 335is? After MUCH debate I've decided to go the JB4 route for added power but I'm still unsure about adding a CAI. Ive read a lot of conflicting info on the CAIs: stock is better, aftermarket can harm the engine, no performance advantage, etc etc... I definitely like the added turbo spool sound but is that really all it's good for?

Its as compared to what. A 335is with a JB4/BMS Tune & a mix of E85/93 & no other performance equipment has run 11.9 @ 117mph with the stock system. I have always been against them unless you were well up into the 400whp range because the stock system with the high 11 second run strongly suggests the stock unit is OK for 400 odd whp.

That being said I am using an aftermarket charge pipe & found it easier to get a stuff on the drivers side of the engine with the BMS/DCI. Undo two worm clamps & they are out as compared to the more time intensive removal of the stock airbox. So my bottom line is unless you have a reason to remove the stock unit leave it in. The DCI functionally add some intake noise to the car but does nothing for power in a light to middle modified car.

Thanks Bear. That's what I thought. Just wanted some confirmation. On another topic. What's the deal with the BMS back end flash? I've seen you and others mention it and I wasn't sure if it's something I will need to do at some point.

Its an additional way to get extra power without extra hardware. Key is available fuel, E85 or 100 race gas. If you don't have fuel to mix into 91/93 to raise the overall octane its not a good investment. Unlike the 335i model that can load the flash with a $187 BT cable The 335is requires a COBB unit which is in the range of $700 brand new. There are V2 COBB'S floating around the site at a better price because a V3 unit has been recently released. Either unit is just fine. If you buy new Terry is a COBB dealer & you might be able to get a discount.

Running pretty much everything the same as on my normal Map 6 I am up from 370/375whp to a bit over 400whp on a 50/50 93/100 mix. This costs me about $25/30 extra a tankful since the 100 octane comes from the pump at the gas station not from 55 gal barrels or a gas truck at the track. I can also run the BMS Map 7 if I have straight 100 octane in the tank like you would do for a day at the track. My Map 7 logs are very good but I have not had it on a dyno so I donít know what the actual WHP for 100 is. It is noticeably stronger than the 50/100 mix but its still just a butt dyno so I canít put any numbers to it.

If you canít get the fuel its best to just work at optimizing what you have. 370whp as measured by a DynoJet machine can be expected from your car.

Ok Thanks. Sounds like running E85 and the BMS backend flash might be something to get into down the road. It's interesting that with the 335is we need the COBB unit vs the BT cable.

Which maps did you run with just the JB4 on your 335is? I'm thinking about getting downpipes and FMIC at some point just not right off the bat.

You may wish to consider this after, say, LSD install. Long after, actually....a Poseur purchase.

Map 6. The default settings from BMS are 335is specific settings. Its designed for 93 octane fuel. Since I run higher octane I increased it .5psi at a time logged it till I had too much boost & was pulling ignition timing & backed it down .5psi.

Yesterday was setting up a test for the BMS charge pipe running 100% 100 octane race gas, available from a somewhat local station at the pump, the computer logs & butt dyno said I was slipping the tires on the 2/3 & 3/4 shifts. This was causing ignition pull but it was still a very eye opening run. It was colder that normal here, low 40's, & my summers had exceeded their level of competency.

Lol. That's one thing I never want to be! I'm going to throw the JB4 on this week with some new plugs and walnut shell blasting. I just found a place running a special on it for $350.

Ok. The reason I'm asking is because the guys at burger suggested I run map 2 or 5 on the 335is with 93 octane. They also suggested the DCI for additional 10 hp on map 2. I would rather get my info from you guys who are very knowledgable and out there using it. Thanks bear!
