Spice up My 318ti M42 intake

[318ti_pt]

Hello i´m thinking of do this to my airbox i have a drop in k&n filter:

or put one of this intake filter with Heat Shield for cold air:

"Superflow Heat Shield Filter combines a conical front design with a heat shield to allow access to cooler air. This improves performance which increases HP and, more significantly, increases torque."

What do you think its better to gain some power/torque?

an intake doesn't really add any power, it does give the engine a little sportier sound to it and looks cool when you pop the hood though, so I'd say get it, just don't expect your car to be much faster

that piece of **** looks restrictive as hell.

This is the best "open" what ever you call it filter you can find. I just have one attached to my MAF. Buying an aftermarket "cold air intake" is pretty much all bull****.

BMW intakes really are not that restrictive, you may actually lose power going to another setup.

I actually have it sitting on zip ties on the edge of the spout, and the hole on the nose frame.

I have been wondering if there is any power to be found in bolting the M42's intake maifold on in place of the stock M44's.

I find it odd that the m44 is .1 litre bigger.. but makes no more power than the smaller m42

OBDII is more restrictive, they upped the displacement in all the engines in 96 to offset the new emissions standards. Same can be said for the 2.5 >> 2.8 and 3.0 >> 3.2.

[Mad-Machine]

well you know, the 2.8 had a more restrictive intake than the 2.5? You can gain a lot of HP by modifying the 2.5's intake to work on the 2.8. Same with the US version of the 3.2. It used a more restrictive intake

[spidertri]

Yeah but in stock form they have the same hp as the previous versions. That's what I was getting at.

[Mad-Machine]

exactly.. I think BMW hobbled the engines.. the 2.8 with the 2.5 intake and a chip is very close in power to the US spec m3.

just like I think BMW hobbled the m44 as if it were allowed to breath, it would put the same power out as the Eurp spec 320... a 2 litre 6 cylinder that put out all of 150hp.

The m44 puts out more torque than the m42.. because of that it should make more power too

This is not restrictive its a Heat Shield for cold air entry only!!
I think its better then the open ones..

Cool i like it!! Thats what i was thinking to do!!

Are you Satisfy with that filter? is it worth?

Notice some power/torque difference?

tell us what you think..

When you understand thermodynamics let me know. Once its heatsoaked. (maybe 5 minutes after you start up) That "head shield" is useless. Just get a cone filter, and then build a heat shield that isolates that part of the engine bay if you really want something that is a "heat shield"

Your not going to notice horsepower/torque gains out of an intake, sorry. Especially not on a BMW. BMW engineers their cars quite well would you not agree? If you bolt on a simple intake or an exhaust to a pretty much stock car, you will get no gains, hell you might even lose power. The factory actually makes amazing products that give great power for a stock motor. Unless you have done something serious to your car, an intake will do nothing for you. Sorry. By looking at your "7 best mods" I see nothing that is a performance modification that would require you to have some crazy intake system.

Spend $20 get a cone filter. Its washable so you will never have to buy a new filter. Even if you don't get a performance gain, that lifetime filter is worth the money. Plus IIRC K&N's have a warranty, I doubt what ever you wanted to does.

Yea, I'm satisfied with it. I only spent $17 shipped. It's very pleasing to the eye, and catches the attention of many. I really didn't notice much power difference once the engine got warm. But while the engine is warming up, it seemed a lot more responsive than before. But once it's really warmed up (like 1 hour later), the response is slower. I'm gonna build a heat dam, and get a intake tube to attached to it from behind the bumper.

I'll agree that there is little to be gained from an intake alone, however, when I did the Fogg mod to my airbox I definitely noticed a little extra oomph in the upper rpms. I don't have any proof other than the butt dyno, but I was happy with the results of the mod for such a small cost. It also allowed me to keep the stock airbox/filter set up.

That said, for the "gains" I received from the intake mod, it is in no way worth the money to buy a CAI. The benefit vs cost isn't worth it at all.

From my limited understanding of air flow ect ect with engines. The fogging of an airbox doesn't really give you more "power" per say, but it will shift your torque curve a wee bit. That might be what you noticed. You can breathe better in the high rpm range.
