Just wondering if air filter size will have an affect on power. For example, a
(3.5" inlet, 4" length, 4.5" base) air filter versus a
(3.5" inlet, 7" length, 4.5" base) versus a
(4.0" inlet, 7" length, 4.5" base)

running on a IX turbo.

Would the first one, a really small filter choke the turbo? and would there be any power to be had by going to the second or third size? I'd imagine on a gt30 or 35r, the small one may be a restriction, but I wouldn't know and was just wondering if the tuners out there have seen anything of the like.

Thanks.

 

Bump

 

No it doesn't - assuming you stick with the normal sizes out these(already proven), but the type of filter does which too is already proven

 

Um yes they do! We dynoed a turbo integra with a K&N "look" filter on it. Couldnt find a logo. Dynoed 278hp... Took off the filter and dynoed 303hp. No other adjustments. However all you have to do is measure the surface area of the filter material. If one measures out 12" surface area and the other measures out 16" area, which do you think will flow more air?

 

Perrin Filter FTW

 

Amsoil unless you like the extra dirt the perrin will let through.Check the air filter shootout results 2hp is not worth it unless its just a race car.
