I decided to try a little experiment with my A3 and from what i gather this is becoming more of a common mod throughout the car world.
I decided to change the standard air filter too a cone filter inside the standard airbox.
Heres the story, I had a RAM air cone filter lying around that i had bought for my Audi Coupe v6 that i never used. The filter is Rated for up to 265BHP, slightly above what the car should be pushing and if i think its worth it i will possibly by a bigger filter ( i think the filter cost me £27 a year or so back), I bought a spare Airbox from ebay for a quid plus p+p, then once i realised it would quite likely fit i bought a 90 deg elbow and some clips from ebay. Heres the pics of what i done. I have yet too fit it too the car as i only stuck it together an hour ago.
First up the standard airbox (bottom half)
I removed the small trumpet section and then removed the flared section, as luckily the OD of this was the same OD as the Cone filter (80mm)
Next up the Filter and the silicone elbow attached.
NExt up the lower half of the Airbox, note the cross suport for the paper filter, which i need to remove to fit the cone.
Same bit minus the cross bar
Now the cone filter in place.
All that was left too do was too clean all the crap out of the inside of the airbox, screw both halves together and leave it on the kitchen floor, ready for fitting at some point.
The main bonus of this should be improved induction noise(if nothing else hopefully a little improved breathing too) but without excess heat that often occurs when changing the standard filter for a cone filter. Once I get it on the car and tested i'll post an update.
All in it took ten mins too fit the cone in the box, I am tempted to drill multi holes in the airbox too allow more air too get too the filter but i need to have a better poke about the engine bay once i take the airbox out, so i keep the sides exposed to heat sealed up.
If anyone else has done this or similar let me know please.
cheers
