    Default Done the airbox mod (2.2 direct petrol - auto)

    Had to change a sidelight bulb yesterday, so off came the top half of the air filter to gain access. With the cover and filter removed I remembered to take out the piece of plastic, as well as hoover out the leaves and other crud sat in the bottom of the airbox.

    I didn't bother disconnecting the battery to reset the ECU.

    Initially I noticed no change whatsoever. After driving approx 10 miles though I started to noticed there wasn't so much lag when accelerating. I also noticed if I revved the engine from tickover it picked up straight away with no hessitation.

    Not sure if it's just coincidence but the air intake noise seems so much quiter too. That might be down to me reconnecting the outer trunk to the airbox though that the mechanic left hanging down after I had my camchain changed.

    I'm gonna run it for a few weeks now with the inner trumpet removed and see if I notice any fuel increase or other changes. If it starts to drink more fuel the trumpet is being clipped back in.

    As previously mentioned, the lag and hesitation has gone. There is a slight fuel increase (uses approx 2 mpg more at most), but that could be just down to the cold weather.

    I was tempted to refit the trumpet during the snow and ice as having instant throttle response kept spinning the front tyres and I had to use the loud pedal as if there was an egg between it and the sole of my shoe. At least with the slight hesitation I had a bit more control on the slippery stuff.

    Scratches to the back of my hand have healed up too - where I changed the sidelight bulb. Bumper off next time.

    It was down to the cold weather. Fuel consumption during the warmer months is the same as it's always been.
