Cold Air Intake?

[Agent Orange]

I recently got a 91 318i.

I've been reading up looking for some decently low-cost preformance upgrades, and it seems like everyone reccomends an intake upgrade. I've been seeing cold air intakes, and everyone raves about them, but do they provide a significant boost over any other intake upgrade on our E30's?

Can anyone reccomend an intake other than K&N? Those are the only ones I've been reccomended so far.

Any info is appreciated.
Thanks.

KN is basically the way you should go for reliability and such, you will hear a difference, and feel a little difference, it isnt like 40hp, its more like 5whp gain at most, if you want to feel a good increase, get a TMS Chip, but you will need 91 octance gas to have that.

what kinda gains we looking at? Hell I've been putting premium in my car the last couple fillups, can't hurt any more

[spiff325is]

gains for the KN Filter(im assuming your talking about the cone filter, not drop in), you'd be looking at somewhere between 3-6whp, for a chip, you could be looking at 12-19whp gain(you need 91 for the chip, not the filter)

i have a K&N racing filter from bavauto, it significantly changes how the car sounds, especially in the 3,000 rpm + range, i recommend it, mine was $150

You paid $150 for a cone filter? Haha. And a cone isn't 3-6HP. It's more like .5-1

SynSyx, which filter was that? I'm not seeing it on their site... did you get the full induction kit with the heatshield, and hardware, or just the filter?

I also heard that using a drop-in filter, and cutting out the bottom of the stock airbox will give nearly the same gains, sound good and cost a fraction of the K&N kit.... any thoughts?

yeah I meant the chip, so all it takes is putting 91 in there and 12-19 horsepower just that easy? Where can I get one of these?

Bav auto rips you off on the kone filter deal, only reason id order through them is if i was lazy and didn twant to buy the mounting hardware.

but you can get the cone filter made by KN for like 50$ on ebay.
ive never heard of drilling holes in the bottom of your air box, does that really help?

[e30fanm3]

the cone filter only gives you like 3hp so drilling holes will only give you like .5hp. if you are gonna buy a kit then buy one with a heat sheild, thats the only way i would buy a kit, but dont expect to really notice a difference, i cant even hear one unless i have the hood up and i rev it with the throttle body, of course my exhaust is louder

you can't really notice a diff, sounds throatier, i can hear it with the hood closed and i have flowmaster exhuast. im going to be doing a cold air kit in a week or so but for the mean time you get a little better flow and a nicer intake sound. if you hve the time just make the cold air intake, if not drilling holes is an easy 30 second way to make it sound a little better and get an unoticable better flow:P

its loud, i have 50 serries its the wrong one i recomend the delta flow 60 serries, or the import muffler they have i forget what its called. but one of those 2 would sound a lot better then what i have. its good idling and low rev's but higher it gets a little tin canish cause the 50 serries is for larger displacment engines.
