Question Cold Air Intake question

Cosmos racing (montreal) has 3.5" for $144.00 + shipping and GST
US venders have 3" for @25.00 USD + shipping and exchange (approx. $70.00cdn landed)

Is their $70.00 worth of gain from the extra 1/2" in diameter of the CAI???
I like buying Canadian but for twice the price?????
Thanks in advance for your opinions!

Cosmos uses a K&N filter, no name probably does not. Its quality of parts included in the kit that will make the difference, not the extra half inch. Im not even sure what the diameter of your intake pipe is, i think its 3.5, but if its 3 than the extra half inch really wont accomplish anything.

remember to position your car somewhere where it gets optimally cold air, lots of people run CAI's or cones without proper heat shields and actually just suck hot air into their engine

you can't use the 3.5" intake unless you have a 3.5" air flow meter. If yours is stock, get a 3" CAI

Yea, your probably right...K&N filter as opposed to coton/ foam
Anyone know what size air intake an M50 engine has? 3-1/2"??
Prop'rone, re the placement...yep, I am only looking at the CAI that extends down behind the headlight for direct cold air

I've been told that debaffling has the same effect as a CAI and it's free...

hmmm, Cosmos 3-1/2" unit says it fits 325 M50 engine?? Also does not say K&N filter, 3" form US says 325/ M50 fit up as well...now I am confused!

I have been thinking of debaffling...might try it this weekend...and just through in a K&N filter in the stock set up...BUT I hear this only gets ~4hp gain vs. CAI at 8 to 10hp gain? I am going to chip the car in a while but want to get a few added horses first)
BTW you need to update your pic to show off the projectors and nice white skirts

i can tell you from experience that a cai is WAY more effective then debaffling.

debaffling only makes your car louder on higher rpm's

yes they do, its very tight but they do fit. although some of my friends had to change thier cone to fit for some CAI's, my old CAI fit just fine, just had to adjust the position it sat.

Read up on the Cosmo racing web page and it says the main section in 3-1/2" with the smaller part that mates to the intake is 3"
So I am inclined to go with the cheeper unit (3") out of the US
