And for $400 less - grab a JB4

You cannot use the STETT CAI on the 335iS. The IS has a secondary radiator in the air duct where the STETT filter would go, there just isnt any room

See above answer to the STETT CAI

I had a similar issue with the support brace running from the middle from of the frame across to the top driver side of the frame.

Unfortunately this had to be removed, but fitment was okay once you play around with it. I also removed the driver air/brake duct as it was in the way - but it was worth it.

Immediately saw the intake temps go down on daily driving and spirited driving and felt so much more responsive. And this is when I was tune only and tune off.

I don't like ram style intake - the purpose of the intake is for colder volumes of air to increase efficiency/power; don't understand that when the volume is hot air - kills any progress.

I agree with Kevin....you can do a lot with $700....FMIC or DPs...

MR.5 Intake is the win win here, i think there was one already built in the FS threads.

It does not fit on the 335is. So it not a win for this car. This post is about the N54 335is not the N54 335i

And yes I did search and didn't come up with much.

Brother just turn up the radio :-p

No Seriously if you're running more boost you should install meth to lower the charge pipe temp. DCI works best with more boost more air more power. Meth adds ignition

If you go DP the noise is also masked by a growling 6 pot

Sound rocks

The aFe Stage 2 SI Elite produced 13 whp and 17 wtq in 93°F over the Stock with K&N Drop in Filter




OP

Jeff@TopGearSolutions offers the best deal on this intake

It seems you posted these in support against DCI for this model car. As the findings reported by Cobb and a End User, the stock box is better.

On this standing, the aFe Stage 2 out performed stock box itself especially in higher temps.
