Over 10 years ago I was playing with the air in take on my 94 +8, I took off the trumpet and put on a K&N open ended filter but didn't want it exposed to the engine heat. I removed the trumpet part from the canister and reverse fit over the filter, then I put the 2 inch hose from below the frame up to the filter housing for cold air. Before this modification I did a rolling road test after the mod carried out another test and found a 5% increase. Many thousands of miles later in all weathers I have had no issues.
That is quite cool britmog. (PUN!) BTW, by removing the trumpet nose you also eliminated an inherent blockage that dealer supplier K&N filters create. Have you ever looked at the gomog article here?
https://www.gomog.com/allmorgan/art3.html (scroll down to air filters) They use the K&N previously use with the Flapper EFI holder (looks like a American football helmet). The holding plate blocks the air flow. When the factory gave me a polished stainless trumpet holder (they knew I am a sucker for shiny metal). However, when testing for other things, I noticed MY bhp had dropped 6%!!
The pictures in the article show why, The Flapper K&N filter in a Hotwire holder blocks air.
I found a small K&N with more air flow and fit it instead...I went right back up to the football helmet figures.
Well done fella
