i like the cone filter , used a foam filter when i was racing dirt dikes , they will fall apart.

i agree with above about the breather tube pinching.

now for your next project.

i installed a ultra gauge( love it ) on my 97 240sx ,112000 mi , at , injen cai with injen back heat shield , greddy cb , underdrive crank pulley , things i found out was with the outside air temp at 80 degrees , engine at 180d the cai temp was 115 degrees with the filter about 1 foot above the air intake hole ( maf / iat sensors at the filter ).

went to lowes and bought a flex 3" tube , cut it to size and put the filter down to the outside air hole , the iat temp went down to about 105d , back to lowes , bought a piece of flat ac duct tin , formed it to shield about 90% of the air filter to block exhaust/engine heat , now the intake air temp is about 10 degrees above outside air temp .

i honestly believe that cars will run better with a stock air box than a std cai filter as the filter is putting a lot of eng/exh heat thru the intake , it may sound better with a cone filter but the engine is nothing but a air pump and cold air is more dense than hot air.

we see many test of cai's vs stock filter setups but they always use the same air temp going in and the cai are better when the temp is the same.

but the way people set them up i think they defeat the cai idea,

just my 2c
