I dont see how they improve the performance of the engine, I thought the idea was to get cold air into the engine these trumpets must pull in hot air from around the engine unless air scoops are cut into the rear boot lid .

Any images or fitting instructions for these trumpets please ??
There are 2 types around. The more expensive ones (if you can find them) are individual and just push into place. I bought a cheaper unit, new, that has the three horns (70 mm length) welded to a plate that gets fixed with an existing bolt. Not hard to fit. It was a pretty crude thing though and I did a lot of smoothing first. It's thin aluminum and I worry about corrosion, but it seems to add some push above 7000 rpm
Past Hondas:
1960 125cc Honda Benly CB92R
1964 305cc Super Hawk CB77, the only vehicle I have ever bought new in my life!
Honda CB160, roadraced as 175cc 1967-1970.
Honda Lawnmower, bought used in 2003, caught fire and melted in 2005.
Thanks Folks , so i did do it right and also used a new filter , i can definatly say it sounds much nicer ,but as someone who isnt mechanically minded can someone explain to me what these trumpets are supposed to do and how that works . Mine are the individual ones .
Cheers
