    S3 Airfilter Heat Advice

    Good Evening all,

    I have very recently purchased my self a 2003 S3 and straight away fitted a pipercross cone filter (as its one of the few things I can do myself). I was really chuffed with myself until I showed one of my friends, who said "those engines get bloody hot and thats just going to be stucking hot air in" ...

    Is this true? and if so what is the best next step?

    Thanks

    Jake

    You can fit a heat shield, there are some on eBay, but they are not a necessaty, a friend of mine has his S3 running 360bhp without a heat shield and he has no overheating problems. I fitted one just for good measure

    Its what your intercooler is for... the temps of the air coming out of the turbo preintercooler can be 150 degrees... not really gonna make loads of difference in the grand scheme of things...

    However... foam filters aren't the best... they need to be oiled quite a bit to be effective and this oil kills MAF sensors...

    Also looks like the one you have fitted has a neck size smaller than the MAF.. this can funnel the air over the MAF sensor causing it the read incorrectly... most cone filters fit over the end of the MAF

    Thanks both for the replies.

    tuffty, what other options did I have? I rushed this decision being the impulsive tool I am.

    If the MAF was to read incorrectly, would this affect the car in anyway?

    Thanks

    If you had more pipe between filter and maf you'd probably get more uniform and accurate airflow over the sensor.

    but the inlet on the filter should at least be the same size as the maf tube I.D.

    While an heat shield as said will have arguably no effect, what it will do is hold the MAF steady for correct readings..

    If the MAF in reading incorrectly does this affect the performance of the car?

    Thanks

    Also does anyone have or could send me in the direction of a picture of what a filter should look like fitted properly?

    Would I be able to feel it driving if the MAF was reading incorrectly?

    Hopefully attached is a close-up ... worth replacing it?
