Hi i have twin idf webers on my 1700 xflow.i tried trumpets 50mm but the front trumpet is very close 5 to 10 mill to the bonnet when shut so i now have 45mm kn filters but should i have trumpets/rampipes maybe up to 20mm inside or ok to run without? Or could i put shallow airbox on with a pipe to ram air from outside? Any thoughts
Cheers
