You can remove the trumpet and still keep the cold air feed to the wing as i have done. I just removed the trumpet/cold air feed by gouging the four lugs that hold it into the air box with a screw driver. It all then comes out in one piece. I then cut the trumpet bit off leaving the lugs in place and the cold air piece just clicked back in place
I also drilled 24 10mm holes in the wing and front side of the box and fitted a greenair cotton filter and it now feels much more responsive. It has also lost a few nasty flat spots i had and seems to deliver the power much more seamlessly than it did before

TBH, it just feels quicker and torquier than it did before and im even getting torque steer when i accelerate which it never had before!!!!(the last time i had this was on an MG monty turbo

) Its a much cheaper mod to do than fitting an induction kit and gains better results IMHO. The 40 to 80 mph in 4th is now pretty shockingly quick!!! And its the same story throuout the rev range an any gear!!! I seriously need to get my car on a rolling road cos im sure its kicking out lots more than the standard sh!tty 115 bhp!!!!
