Hi Guys,

Wanted to know what induction options there are for an E93.

Want to get a little more grunt out the engine.

Regards,

Buy a 335i


I have read on a few forums that the BMW performance induction system gives good low down power compared to aftermarket CAI system, however the aftermarket CAI perform better at higher speeds, just what I have read

Lol. Your first option sounded good :rollsmile:

Hmm - I will look into the performance induction from BMW.

Next is M3.

I can from a 46 4 pipe. Felt like I was climbing into a citi golf. Power difference is definitely huge.

Since you have that feeling why not get a Simota filter connected to a spring wrapped in tin foil...:=):

Just a suggestion since that mod makes the citi golf kill M3s

intake is not going to give you big performance gains...

on an NA car exhaust, intake, tune and short ratio diff will get you the best bang for buck, but you will still be way off the M3... after those small mods things will get alot more expensive...

BMW Performance Intake Kit for 130i now fitted!!!!

--------------------------------------------------------------------------------
As some of you will already know, I've been treating myself to plenty of goodies of late and spoiling myself somewhat!

Got my BMW Performance Intake delivered and I installed it today also

I've been looking for reviews on this Intake for some time and there haven't been many and none which could convince me to part with UK £570+ for one but an opportunity came along at a price I couldn't refuse!

To be honest I wasn't expecting very much, especially after I opened the box and looked what was inside. It just looked like the same but with Carbon lid on. The filter as mentioned before looks like a K&N type and there is a replacement lid (uses the same box) and a small intake which takes additional air from the bulkhead!


After closer inspection you can see from these pics that the twin air inlets are the same size as the old one but the divider is in a different position


The connecting pipe is much larger though as seen below


and the lid




here's a picture of the smooth lid compared to the old one


picture of the extra inlet that now leads to the bulkhead which replaces the plastic piece


New K&N style filter


The installation for extremely straight forward and took around 30 mins. Not bad considering I had no installation instructions and also that I'm not the best DIY'er.

Now the juicy stuff!
I started the engine with the bonnet open and immediately, I could hear the induction noise. I give it a few blips and to my surprise, I could hear a difference

Closed the bonnet, into the car and the sound was a little muted at idle, thanks to the good sound insulation of the 1er. Drove away slowly and that's when I thought it was as expected. No difference than before from the inside, windows shut.

I decided to give it a little more of the throttle, in gear and suddenly the Intake comes alive! Not much sound below 3k revs and then suddenly the Intake noise comes rushing in! I dipped below 3k and again just like before but as soon as you hit 3k revs it's almost like some valve has opened up and the sound is very noticeable, even with the windows up. I'm liking it!

Now engine warmed up, I decided to find some nice back roads where I recently had a blast in the 135i and also in mine prior to Intake and now I'm really on it and all I can say is WOW!!!!! The induction note put a grin on my face that I was just not expecting and adds something to the soundtrack that simply not there before!!

At this point I wound the drivers side window down and the sound just magnified!! I recently test drove an M3 CSL and I would honestly say that some of the characteristics are there but not as extreme and a little more muted!! This I was not expecting but I had to wind the window down to get the maximum sound track.

The disadvantage (or advantage) of the 1 Series is that it has excellent sound proofing and like the BMWP exhaust you get the most from it with the windows down. Although you can hear the exhaust and Intake in this case, it is well insulated but you can definitely still hear it!

It also felt noticeably faster, although to be honest I'm not sure if this was a placebo effect or perhaps caused by the condition of my previous filter which was rather dirty after only 13k miles!!

It may or may not produce big gains on the Dyno but the subjective feeling of greater responses and more power are definitely there just like the same impression when I changed the exhaust!

My conclusion to this upgrade is that I will say it's every bit as good as the BMWP exhaust upgrade and adds it's own personality to an already great sound track and I whole heartedly recommend this to anyone. Remember, this is coming from a sceptic of this product!

To be honest, I'm rather shocked that some similar bit's of plastic and a new filter can make such a dramatic subjective difference

Early days I know, perhaps the novelty will wear within time but I will post again after spending more time with it.

I remember reading that the US intake is worse than ours and that this upgrade helps them a lot more than us as our current setup is quite similar. Google a pic of a US engine bay to see what I mean. Anyone want to confirm this?

The 3k rev difference he's talking about, would that be solved with a golf tee mod? Although I prefer my car being quiet at low revs...

Yep, they have a carbon pre-filter element of some sort which restricts air intake a bit, so a popular mod over there is the carbon particle filter delete where they actually physically cut it out. But our cars have a completely different intake - does not have this and is cylindrical as opposed to flat.

At the end of the day, there is not really too much on the way of gains for these engines - well not versus the money spent compared to say a 330d. I would go for the BMW Performance intake for the slight improvement, the sound and aesthetically I think it looks pretty cool! But yes, that price!!! :nonono:
