Filter Size On Gsx

I have a K and N filter right now and it has a 4" inlet which is connected to the metal adapter... I need a new filter because mine is worn pretty bad but will getting a different cone filter with a different adapter and a smaller 3" inlet be worse for the performance due to the smaller size of the inlet?

Why would you get a smaller filter? Just get the same size that you have on it.

yea but would that affect performance?

I wouldn't think so, not anything noticeable anyways. A 3" intake is still alot of air intake.

The one i had came with the injen pipe and was also injen... its more like a 4.5" inlet when i measured it so..

The bigger the better. Stick with what you have.

if u can find the filter again stick with it

O/T 100 posts to go WAHOOOOOOO!!!!!!!!!!

Intake Filter designe and size both effect the performance of an engine. I'll find the equation.....

Below is a series of formulas to determine air filter size for a given air flow capacity

1: Square inches of filter required for a motor = CID x Maximum RPM / 20839
2: CFM required for a 4 stroke motor = CID x Maximum RPM / 3456
3: CFM required for a 2 stroke motor = CID x Maximum RPM / 1728
4: CFM required for a turbocharged or supercharged motor = Pounds of Boost / 14.7..
Add 1.0 to this answer. This relates to #2 and #3
Example: (CID x maximum RPM x #4 ) / 3456 or 1728
5: To find circumference of a circle multiply diameter by 3.1416
6: To find diameter of a circle multiply circumference by .31831

Round: Diameter x Height x 6 x 3.14
Flat Panel: Length x Width x 6
Universal Round Taper: (Base + Top) / 2 = A
Take A x Length x 6 x 3.14
Universal Round Straight: Diameter x Length x 6 x 3.14

Hope that helps.

..... umm yea i would just get the biggest one you can fit. i dont like doing math personaly. :disappoin

What size is the filter that comes with the injen intake?

I measured and its like 4.5" for the inlet but i dont know does anyone have a link to one that would replace it using the metal adapter that came with it?

RIDER...if you could get us some pictures it would help out alot.

Bigger is always better or at least for a car anyways

Thats why you'll probably flunk out of school. I don't know why I even try some times.

lmao math is so easy...i dont see why people dont get it..
