i am considering swaping my cone filter to a KnN element in my standard air box . would i benefit from this or would it just be a waste of dollar. series2

would i have to have my car back on the rollers ?

 

A lot of people swear by this method. I want to keep my cone though so my bro is going to knock me up a heat shield to help it from drawing in the warm air

 

on mine i sawed the front of the air box of making the whole huge and put a k&n in, made a big difference in summer (had a slight boost rise due to cooler air) not much in it when its this cold tho

 

on mine i had standard air box with a k&n panel filter and the box has huge holes drilled in it, all along the side and a couple up front. i believe its much better than a cone.

 

I have a std airbox with front cut out with K&N panel filter. My tuner said to keep this on for a better result

 

when i next get my car setup im gonna put my airbox back on and cut the front of it off.

it makes more sense

 

cheers for thereplies would i lose ftLBS in a trade for bhp

thanks

 

cone for me as long you have a good cold air feed/heat shield you will have no problems

 

I have a cone

 

I think Performance Ford did a review on this, it could have been in the RS Turbo Special - will have a look later.

If i remember right, overall it didn't make a huge amount of difference - the std airbox did pull in less warm air but am sure the car produced slightly more power with the K&N cone filter on - as i say it's been a while since i read the article but am bored at work so

I would like my std airbox back on next time the car is set up, as don't like the noise from the K&N and it cheesegrated my hand too many times lately when i've been messing with the car

 

Yes Tony, but yours looks like this......

 

Think it was better Torque with the air box. ?
But air temp was crazy with the cone fitted..

 

i got the results from the Performance Ford test @ Jamsport in front of me and they are:

Standard 174bhp 209lb/ft 36.3oC
Drilled Airbox (standard element) 180bhp 204lb/ft 38oC
Drilled with panel filter (pipercross) 179bhp 195lb/ft 41oC
Cone filter (pipercross) 174bhp 216lb/ft 46.3oC

 

if you use a decent heat shield you'll have no problems with a cone filter!

 

and remember those figure are on an RR real road conditions provides loads more air movement

 

by putting a heat shield around a cone filter you are only recreating an air box....

the only thing the cone filter has going for it is, the un-restrictiveness of it = plenty of air.

i reckon you could get similar effect from an air box with the top half cut out the front of it..

 

tbh i wouldnt be drilling my air box.

my KnN cone has been on my car for 11 years and is looking v worn so was just fishing for ideas

 

the heat shield that i've got doesnt cover the filter,it shields heat from the top water hose away from the filter and is shaped to duct cold air around it
