    Thought this might be of some interest to others. I know its a repost, but the original post was inside another thread.

    So back in the day, when my S3 was a 1.8t and on the road !! I did a log with the standard airbox with a drop in k&n filter.

    The max g/s I could get was 198g/s with the crappy map that was on the car.

    I bought a very large filter (K&N rd-1460) for the stroker build and thought I would test it out on the K04 setup. Excuse the dirty engine and "awesome" plumbing elbow :blush:

    I did a log a few days later with the large filter and found that I had gained 16g/s just from fitting the filter, the power was noticeable and when the DV dumped the boost it sounded like a bus dumping boost - I had the biggest grin on my face for awhile but then it got embarrassing around town. Wouldnt mind the sound if I had 500hp :eyebrows:

    I dont know if a filter will make everyones car a bit better, my guess it would probably come down to the mapping, but it does show how a filter can increase the airflow to the turbo.

    good numbers..
    we see gains from the large JR's over std. I dont remember what we saw on westys when that swap was done, but it was reasonable I recall.

    I thought K&N's were bunk on these engines due to being oiled?

    My plan is to keep on top of filter maintenance and keep the maf clean

    My memory isnt good either. I know the figures are in my thread somewhere. It was around 10bhp and 7lbft if I remember correctly, and that was dyno proven ;)

    Logged the same thing on my LCR, green panel vs a massive green cone and gained about 11g/s on a standard map

    Bill, How'd you go about cleaning such a large, blue JR cone? (I did buy one off you a while back btw).

    Good old "warm soapy water + ensure its dry" jobbie?

    Take it in the shower with you. Warm soapy water is fine. Just make sure it's well dried.
