    Its A long shot but a few years back, on my G60 when wanting power it faded, after many unsuccessful trips to VW specialist I decided to investigate: I found On the fuel Tank top cap where the pipes go into, inside the fuel tank the rubber hose that goes to the pump had a split so pressure wasn't there and leaking fuel back into tank.
    good Luck

    Yeah itís the right way round Jim . I just wrote it wrong . Once the traffic dies down I will go for another spin in it . Itís probably me , it was a really hot day the first time I used the car with it fitted.

    The bmw seems invincible in isolation . But along side the corrado - a modern classic , we think- it has its work cut out . Autocar 1992.

    Ok I admit it was me . Been out for a few miles this evening and she is performing nicely.

    I pulled my K&N filter a few months after buying it. I noticed no increase in anything but noise after I installed it. After 6 months of use, my car seemed to be slow, so I pulled it out thinking it might need cleaning already, and put my old, dirty OE air filter back in during the ridiculous 24 hours it takes to dry the thing. Immediately noticed more power with the dirty OE filter than with the only 6 month old K&N. I threw the K&N in the garbage and never looked back.

    I think the consensus is that "performance" panel and cone filters do absolutely nothing except give more noise, if that is your thing.

    For me the jury is still out on the BMC CDA, some claim a proven increase in power and response, some not. I don't think the kind of gains they might give are reliably measurable, unless under extremely controlled conditions. The BMC is not cheap either.

    OEM airbox and paper filter elements are a good compromise unless running forced induction etc, and even then if you look at fancy factory FI setups, they still mostly use bog standard airboxes and filters.

    Rob? How do you apply the oil to the filter? I've oiled mine once so far and just want to wash and re-oil. Was thinking of putting the oil into a spray bottle rather than using the dropper provided (K&N oil).

    Pretty much in agreement Fender . I just like the extra grunt noise . Pretty much everything comes from the engine on a VR , with a burble from the exhaust. Every time I see /hear a Honda boy it reminds me of a loud fart going up the road
