k&n filter to 1.8T

[vassa_1.8T]

hey guys im new to the forum. i jus purchased a 2000 A4 1.8T and eventually want to make it a bit quicker. as it is completely standard now and i want to keep it that way for a while, will something small like a k&n air filter make any difference to performance? will in make the induction sound of the turbo any louder? what are some other cheap mods to get going? thanks guys

Are you talking about getting a new intake tube from your tb, or jsut the airfilter itself? If just the airfilter, then yes a K&N filter would be better.

As for sound, im not sure you would get much a difference if using stock airbox.

K&N Air filters rarely make any difference to performance, all they do is make a noise.. if thats all you want you may aswell get a panel filter and drill the airbox. Performance gains on air filters alone are negligible, combine it with a full system exhaust and you'll see better gains and a more appealing noise.

the k&n air filter isnt gonna do anything no sound and same proformance. get a full intake system if u want to change the intake and get it revoed 93 octane...dont say cheap cuz money aint a thing for dubs and audis

If you do go ahead, avoid all types of "oiled" filter. They coat the MAF sensor with the oil from the filter which isn't good.

ill just leave it then...i think the money will be better spent on my HSV

I got a k & n air filter on my 98 1.8 and it didn't make any difference in performance or in sound so if i were you i would just spend some money in buying a short ram and that will give you a small amount of performance gains but will make a big difference in the way your car sounds, you will then be able to hear the turbo and the induction sound

An air filter won’t make much difference in performance or sound however a cold air intake induction kit can give you better performance and makes a nice sound.
