Looking to pick up an intake and was wondering what you guys would recommend before I pulled the trigger.

What sort of actual gains can one expect with an aftermarket/performance intake on a 328i ?

From my experience, I've always lost some throttle response and torque in the low rpm and low speeds with a CAI, but gaind the very same at high speed.

The injen intake i have now on my 428i is the first intake that i did not loose any tq or throttle response with.

I went injen as well. In addition to the fellow above it also makes the car sound fantastic with the blow off sounds.

Any other recommendations before I go with the Injen?

How much should I expect to pay. Looking at them on eBay... where did you buy yours?

I picked mine up off eBay as well. I can't remember the price but they were all floating on there around the same range.

i have a injen intake its super load lots of turbo noise if you like that (i do), but simple as K&N filter will do just fine.

Interesting. Wonder why that would be the case considering any other car that Ive owned would at least pick up a few ponies and some claiming to increase HP as much as 15hp. Never bought that claim but zero gains seems ridic.

This is the first turbo car Ive ever owned though... could this be part of the zero gain issue?

i think the most you gain is better throttle response

Ahh. Okay. Well that at least makes the investment worth it... in my mind anyway.

yeah id say so, i did it for spooling sound make the car more fun to drive at least imo

the n20 stock airbox already flows well, so gains are minimal.

for performance, the best bang for your buck is a stage1 piggy back or flash tune.

an intake along with fmic, dp, exhaust and stage2 piggy back(w/code removal) or flash tune is where there is more of a benefit.

Air intake upgrades are generally better for naturally aspirated engines. The only time a turbo engine would typically benefit from an upgraded intake is when you have a large turbo and the intake piping becomes a bottleneck - that's when a larger diameter piping would be beneficial.

The money is definitely better spent in other areas....but I totally understand wanting the noise

Thanks guys. Probably still pick one up anyway if nothing else for improved sound and maybe a slight uptick in throttle response.

Who are the most trusted tuners around the SAC/Stockton/Modesto area?

Not looking to stress my engine and decrease its life by SUPER TUNING it but had my Camaro tuned by Overkill Motorsport and noticed an increase in performance for sure so Im definitely interested...

At best you'd probably get around 5-8whp. Intakes are more for sound than really anything else. I simply dropped a K&N filter in mine and walked away, lol.

Non-car guy: "Whoa, that sounds beastly! What'cha running for hp?"
You: "~8hp over stock!"
Non-car guy: "Nooooice!"
cue chest bumping

Ok, I'm joking but it's really just for sound.

May pick an intake up some day but that's low on my to-do list right now. Pricing new isn't cheap (~$400-600) and eBay would only be a smidgen cheaper I'd guess.

eBay has them for ~300$ shipped. On the hunt...

if you're going to spend at least have it draw in air cooler than the engine bay to improve performance. it doesn't come cheap, though.

i remember the good ole honda days where you had short ram and cold air. short ram, making noise, degrading performance after the engine bay became heatsoaked. cold air had installation shortcomings but generally provided improved performance. although the gauze or foam filters flow better they don't filter as good as paper.

Just grab a used one in the member classifieds section for $180-200

Been looking... and posting...

What is the premier/preferred drop in filter?

If I was to go that route

oiled filters work better however it requires more maintenance and using the appropriate amount of oil. also oil tends break down media (especially foam) after time. dry filters are more "set and forget". just clean with compressed air every so often. here are a couple of dry drop-ins. i think you'll be underwhelmed.

Thanks. Got an offer in on a K&N filter off eBay... for $42.... Buy it Now of $50... free shipping. I guess if an actual aftermarket intake is a complete waste of money, I might as well have a high quality drop in.

i think k&n are oil type. just be sure the oil does not get on the sensors down line in the airflow
